- [$] Checked-size array parameters in C
There are many possible programmer mistakes that are not caught by theminimal checks specified by the C language; among those is passing an arrayof the wrong size to a function. A recent attempt to add some safetyaround array parameters within the crypto layer involved the use of someclever tricks, but it turns out that clever tricks are unnecessary in thiscase. There is an obscure C feature that can cause this checking tohappen, and it is already in use in a few places within the kernel.
- [$] Some 6.18 development statistics
Linus Torvalds releasedthe 6.18 kernel as expected on November 30, closing the last fulldevelopment cycle of 2025. It was another busy cycle, featuring a recordnumber of developers. The time has come for a look at where the code camefrom for this kernel release, but also for the year-long long-term-supportcycle which has also reached its conclusion with this release.
- Security updates for Monday
Security updates have been issued by AlmaLinux (bind9.18, cups, gimp, ipa, kernel, libssh, mingw-expat, openssl, pcs, sssd, tigervnc, and valkey), Debian (gnome-shell-extension-gsconnect, mistral-dashboard, pagure, python-mistralclient, pytorch, qtbase-opensource-src, sogo, tryton-server, and unbound), Fedora (cef, drupal7, glib2, linux-firmware, migrate, pack, pgadmin4, rnp, and unbound), Slackware (libxslt), SUSE (cpp-httplib, curl, glib2, grub2, kernel, libcoap-devel, libcryptopp, libwireshark19, postgresql15, and postgresql17), and Ubuntu (edk2).
- Three stable kernels for Monday
Greg Kroah-Hartman has announced the release of the 6.17.10, 6.12.60, and 6.6.118 stable kernels. As usual, eachcontains a number of important fixes throughout the tree. Users areadvised to upgrade.
- The 6.18 kernel has been released
Linus has released the 6.18 kernel, as expected.
So I'll have to admit that I'd have been happier with slightly less bugfixing noise in this last week of the release, but while there's a few more fixes than I would hope for, there was nothing that made me feel like this needs more time to cook. So 6.18 is tagged and pushed out.
Headline changes in this release includethe abilityto manage namespaces with file handles,support for the AccECNcongestion-control protocol,initial support for signing of BPFprograms,improved memory management with sheaves,the Rust binder driver,better control over transparent hugepages,and a lot more.This release also saw the removalof the bcachefs filesystem.
See the LWN merge-window summaries (part 1, part 2)and the KernelNewbies 6.18page for more information.
- NixOS 25.11 released
Version25.11 of the NixOS distribution has been released. "The 25.11release was made possible due to the efforts of 2742 contributors, whoauthored 59430 commits since the previous release". Changes include7,002 new packages, GNOME 49, LLVM 21, a new COSMIC desktopenvironment beta, firewalld support, and more; see therelease notes for details.
- Landlock-ing Linux (prizrak.me)
The prizrak.me blog is carrying an introduction to theLandlock security module.
Landlock shines when an application has a predictable set of files or directories it needs. For example, a web server could restrict itself to accessing only /var/www/html and /tmp.
Unlike SELinux or AppArmor, Landlock policies don't require administrator involvement or system-wide configuration. Developers can embed policies directly in application code, making sandboxing a natural part of the development process.

- KDE Plasma 6.8 will be Wayland-only
KDE's Plasma team has announcedthat KDE Plasma will drop X11 session support with Plasma 6.8:
The Plasma X11 session will be supported by KDE into early2027.
We cannot provide a specific date, as we're exploring thepossibility of shipping some extra bug-fix releases for Plasma6.7. The exact timing of the last one will only be known when we getcloser to its actual release, which we expect will be sometime inearly 2027.
What if I still really need X11?
This is a perfect use case for long term support (LTS)distributions shipping older versions of Plasma. For example,AlmaLinux 9 includes the Plasma X11 session and will be supporteduntil sometime in 2032.
See the blog post for information on running X11 applications(still supported), accessibility, gaming, and more.
- Security updates for Wednesday
Security updates have been issued by AlmaLinux (bind, binutils, delve and golang, expat, firefox, haproxy, kernel, libsoup3, libssh, libtiff, openssh, openssl, pam, podman, python-kdcproxy, shadow-utils, squid, thunderbird, vim, xorg-x11-server-Xwayland, and zziplib), Debian (cups-filters, libsdl2, linux-6.1, net-snmp, pdfminer, rails, and tryton-sao), Fedora (chromium, docker-buildkit, docker-buildx, and sudo-rs), Gentoo (librnp), Mageia (webkit2), SUSE (amazon-ssm-agent, buildah, curl, dpdk, fontforge-20251009, kernel, libIex-3_4-33, librnp0, python311, rclone, and sssd), and Ubuntu (linux, linux-aws, linux-aws-6.8, linux-ibm, linux-lowlatency, linux-lowlatency-hwe-6.8, linux-nvidia, linux-nvidia-6.8, linux-nvidia-lowlatency, linux-oracle, linux-aws-6.14, linux-oracle-6.14, linux-aws-fips, linux-fips, linux-gcp-fips, linux-realtime, linux-realtime-6.8, mupdf, openjdk-17, openjdk-8, and openjdk-lts).

- AlmaLinux 10.1 released
AlmaLinux 10.1 has been released. Inaddition to providing binary compatibility with Red Hat EnterpriseLinux (RHEL) 10.1, the most notable feature in AlmaLinux 10.1 isthe addition of supportfor Btrfs, which is not available in RHEL:
Btrfs support encompasses both kernel and userspace enablement, and itis now possible to install AlmaLinux OS on a Btrfs filesystem from thevery beginning. Initial enablement was scoped to the installer andstorage management stack, and broader support within the AlmaLinuxsoftware collection for Btrfs features is forthcoming.
In addition to Btrfs support, AlmaLinux OS 10.1 includes numerousother improvements to serve our community. We have continued to extendhardware support both by addingdrivers and by adding a secondary version of AlmaLinux OS and EPELto extend support of x86_64_v2 processors.

- [$] APT Rust requirement raises questions
It is rarely newsworthy when a project or package picks up a newdependency. However, changes in a core tool like Debian's Advanced PackageTool (APT) can have far-reaching effects. For example, JulianAndres Klode's declarationthat APT would require Rust in May 2026 means that a few of Debian'sunofficial ports must either acquire a working Rust toolchain ordepend on an old version of APT. This has raised several questionswithin the project, particularly about the ability of a singlemaintainer to make changes that have widespread impact.

- Singapore Extends Secondary School Smartphone Ban To Cover Entire School Day
Singapore's Ministry of Education has announced that secondary school students will be banned from using smartphones and smartwatches throughout the entire school day starting January 2026, extending current restrictions beyond regular lesson time to cover recess, co-curricular activities, and supplementary lessons. Under the new guidelines, students must store their phones in designated areas like lockers or keep them in their school bags. Smartwatches also fall under the ban because they enable messaging and social media access, which the ministry says can lead to distractions and reduced peer interaction. Schools may allow exceptions where necessary. Some secondary schools adopted these tighter rules after they were announced for primary schools in January 2025, and the ministry reports improved student well-being and more physical interaction during breaks at those schools. The ministry is also moving the default sleep time for school-issued personal learning devices from 11pm to 10.30pm starting January.

- A Windows Update Broke Login Button, and Microsoft's Advice is To Click Where It Used To Be
Microsoft has acknowledged that a recent Windows preview update, KB5064081, contains a bug that renders the password icon invisible on the lock screen, leaving users to click on what appears to be empty space to enter their credentials. The issue affects Windows Insider channel users who installed the non-security preview update. The company's suggested workaround is straightforward if somewhat absurd: click where the button should be, and the password field will appear. Microsoft said it is working to resolve the issue.

- Waymo Has A Charging Problem
The Santa Monica City Council has unanimously voted to order Waymo to halt overnight charging operations at two outdoor depots near Broadway and 14th Street after months of resident complaints about constant beeping from reverse sensors, noise from charging equipment, traffic congestion and flashing lights between 11 p.m. and 6 a.m. As many as 56 autonomous vehicles charge at the two sites. It's unclear whether Waymo or its Virginia-based charging operator Volterra intends to comply. The Los Angeles Times reported that neither company planned to, claiming city officials misunderstood their existing permit rights. Waymo told the newspaper it had adjusted operations in response to neighbor feedback and would continue seeking community input, though the company did not address the order directly. Local law enforcement has gotten involved after at least one person attempted to disrupt operations at the facilities on several occasions. The dispute points to a broader challenge facing the autonomous vehicle industry: charging depots need to be close to service areas to minimize deadhead miles (distance traveled without revenue-generating passengers), but situating them in residential neighborhoods creates exactly these kinds of conflicts.

- Netflix Kills Casting From Phones
An anonymous reader writes: Netflix has removed the ability to cast shows and movies from phones to TVs, unless subscribers are using older casting devices. An updated help page on Netflix's website, first reported by Android Authority, says that the streaming service "no longer supports casting shows from a mobile device to most TVs and TV-streaming devices," and instead directs users to navigate Netflix using the remote that came with their TV hardware.

- Colleges Are Preparing To Self-Lobotomize
The skills that future graduates will most need in an age of automation -- creative thinking, critical analysis, the capacity to learn new things -- are precisely those that a growing body of research suggests may be eroded by inserting AI into the educational process, yet universities across the United States are now racing to embed the technology into every dimension of their curricula. Ohio State University announced this summer that it would integrate AI education into every undergraduate program, and the University of Florida and the University of Michigan are rolling out similar initiatives. An MIT study offers reason for caution: researchers divided subjects into three groups and had them write essays over several months using ChatGPT, Google Search, or no technology at all. The ChatGPT group produced vague, poorly reasoned work, showed the lowest levels of brain activity on EEG, and increasingly relied on cutting and pasting from other sources. The authors concluded that LLM users "consistently underperformed at neural, linguistic, and behavioral levels" over the four-month period. Justin Reich, director of MIT's Teaching Systems Lab, recently wrote in The Chronicle of Higher Education that rushed educational efforts to incorporate new technology have "failed regularly, and sometimes catastrophically."

- Top Consultancies Freeze Starting Salaries as AI Threatens 'Pyramid' Model
Major consulting firms including McKinsey, Boston Consulting Group and Bain have frozen starting salaries for the third consecutive year as AI reshapes how these companies think about their traditional reliance on large cohorts of junior analysts. Job offers for 2026 show undergraduate packages holding steady at $135,000-$140,000 and MBA packages at $270,000-$285,000, according to Management Consulted. The Big Four -- Deloitte, EY, KPMG, and PwC -- haven't raised starting pay since 2022. The industry's classic "pyramid" structure, built on thousands of entry-level employees who crunch data and assemble PowerPoint decks, faces pressure as AI automates much of that work. Two senior executives at Big Four firms estimated that UK graduate recruitment would fall by about half in the coming year. PwC has already cut graduate hiring in 2025 and said in October it would miss a target to add 100,000 employees globally by 2026 -- a goal set five years ago before generative AI's rollout.

- India Orders Mobile Phones Preloaded With Government App To Ensure Cyber Safety
An anonymous reader shares a report: India's telecoms ministry has privately asked all smartphone makers to preload all new devices with a state-owned cyber security app, a government order showed, a move set to spark a tussle with Apple, which typically dislikes such directives. [...] The November 28 order, seen by Reuters, gives major smartphone companies 90 days to ensure that the government's Sanchar Saathi app is pre-installed on new mobile phones, with a provision that users cannot disable it. [...] In the order, the government said the app was essential to combat "serious endangerment" of telecom cyber security from duplicate or spoofed IMEI numbers, which enable scams and network misuse.

- Airbus Says Most of Its Recalled 6,000 A320 Jets Now Modified
Airbus said Monday that the vast majority of around 6,000 A320-family jets affected by an emergency software recall have now been modified, leaving fewer than 100 aircraft still requiring work after a frantic weekend of repairs prompted by the discovery of a vulnerability to solar flares. The unprecedented recall -- described as the broadest emergency action in the company's history -- came after a mid-air incident on a JetBlue A320 revealed a possible link between a drop in altitude and a space-related computer bug. The fix involved reverting to an earlier version of software that controls nose angle, uploaded via cable from a portable device called a data loader. Some older A320 jets will need entirely new computers rather than a simple software reset, raising questions about how long those aircraft will remain grounded amid global chip shortages. Reuters separately reported on Monday that Airbus had discovered an industrial quality issue affecting metal panels of a "limited" number of A320-family aircraft. The company told the publication that it had "identified" and "contained" the source of the issue and that "all newly produced panels conform to all requirements."

- China's Central Bank Flags Money Laundering and Fraud Concerns With Stablecoins
China's central bank has flagged stablecoins as a specific concern in its latest push against virtual currencies, warning that the tokens fail to meet requirements for customer identification and anti-money-laundering controls and risk being used for fraud, money laundering, and unauthorized cross-border fund transfers. The People's Bank of China released a statement Saturday following a Friday meeting on virtual currency regulation, saying crypto speculation has recently increased due to various factors and now presents new challenges for risk control. Virtual currencies do not hold the same legal status as fiat currency and cannot be used as legal tender, the bank said, adding that all virtual currency-related business activities are "illegal financial activities." China banned cryptocurrency trading in 2021. The bank said it will intensify efforts to combat illegal financial activities to maintain economic and financial stability. In October, PBOC Governor Pan Gongsheng said the central bank would closely track and evaluate the development of overseas stablecoins.

- Former CEO Blasts Intel's 'Decay': 'We Don't Know How To Engineer Anymore'
Pat Gelsinger, the former Intel CEO who was pushed out in late 2024 during a five-year turnaround effort, told the Financial Times that the "decay" he found when he returned to the company in 2021 was "deeper and harder than I'd realized." In the five years before his return, "not a single product was delivered on schedule," he said. "Basic disciplines" had been lost. "It's like, wow, we don't know how to engineer anymore!" Gelsinger was also unsparing about the Biden administration's implementation of the 2022 Chips Act, legislation he spent more time lobbying for than any other CEO. "Two and a half years later [and] no money is dispensed? I thought it was hideous!" There's what Gelsinger carefully calls "a touch of irony" in how things played out. Intel's board forced him out four years into a five-year plan, then picked successor Lip-Bu Tan -- who Gelsinger says is following the same broad strategy. Tan has kept Intel in the manufacturing game and delivered the 18A process node within the five years Gelsinger originally promised. Asked what went wrong, Gelsinger conceded he was "very focused on managing 'down'" and should have managed "up" more. He also would have pushed harder for more semiconductor expertise on the board, he said.

- Two Former US Congressmen Announce Fundraising for Candidates Supporting AI Regulation
Two former U.S. congressmen announced this week that they're launching two tax-exempt fundraising groups "to back candidates who support AI safeguards,"reports The Hill, "as a counterweight to industry-backed groups."Former Representatives Chris Stewart (Republican-Utah) and Brad Carson (Democrat-Oklahoma) plan to create separate Republican and Democratic super PACs and raise $50 million to elect candidates "committed to defending the public interest against those who aim to buy their way out of sensible AI regulation," according to a press release... The pair is also launching a nonprofit called Public First to advocate for AI policy. Carson underscored that polling "shows significant public concern about AI and overwhelming voter support for guardrails that protect people from harm and mitigate major risks." Their efforts are meant to counter "anti-safeguard super PACs" that they argue are attempting to "kill commonsense guardrails around AI," the press release noted... The super PAC is reportedly targeting a Democratic congressional candidate, New York state Assemblymember Alex Bores, who co-sponsored AI legislation in the Albany statehouse. "This isn't a partisan issue — it's about whether we'll have meaningful oversight of the most powerful technology ever created," Chris Stewart says in their press release. "We've seen what happens when government fails to act on other emerging technologies. With AI, the stakes are enormous, and we can't afford to make the same missteps."

- Amazon and Google Announce Resilient 'Multicloud' Networking Service Plus an Open API for Interoperability
Their announcement calls it "more than a multicloud solution," saying it's "a step toward a more open cloud environment. The API specifications developed for this product are open for other providers and partners to adopt, as we aim to simplify global connectivity for everyone." Amazon and Google are introducing "a jointly developed multicloud networking service," reports Reuters. "The initiative will enable customers to establish private, high-speed links between the two companies' computing platforms in minutes instead of weeks."The new service is being unveiled a little over a month after an Amazon Web Services outage on October 20 disrupted thousands of websites worldwide, knocking offline some of the internet's most popular apps, including Snapchat and Reddit. That outage will cost U.S. companies between $500 million and $650 million in losses, according to analytics firm Parametrix. Google and Amazon are promising "high resiliency" through "quad-redundancy across physically redundant interconnect facilities and routers," with both Amazon and Google continuously watching for issues. (And they're using MACsec encryption between the Google Cloud and AWS edge routers, according to Sunday's announcement:As organizations increasingly adopt multicloud architectures, the need for interoperability between cloud service providers has never been greater. Historically, however, connecting these environments has been a challenge, forcing customers to take a complex "do-it-yourself" approach to managing global multi-layered networks at scale.... Previously, to connect cloud service providers, customers had to manually set up complex networking components including physical connections and equipment; this approach required lengthy lead times and coordinating with multiple internal and external teams. This could take weeks or even months. AWS had a vision for developing this capability as a unified specification that could be adopted by any cloud service provider, and collaborated with Google Cloud to bring it to market. Now, this new solution reimagines multicloud connectivity by moving away from physical infrastructure management toward a managed, cloud-native experience. Reuters points out that Salesforce "is among the early users of the new approach, Google Cloud said in a statement."

- Russia Left Without Access to ISS Following Structure Collapse During Thursday's Launch
After a successful November 27th launch to the International Space Station, Russia discovered an accident had occurred on their launch site's mobile maintenance cabin — when a drone spotted it lying upside down in a flame trench."The main issue with the structure collapse is that it puts Site 31/6 — the only Russian launch site capable of launching crew and cargo to the International Space Station (ISS) — out of service until the structure is fixed," reports the space-news site NASA SpaceflightThere are other Soyuz 2 rocket launch pads, but they are either located at an unsuitable latitude, like Plesetsk, or not certified for crewed flights, like Vostochny, or decommissioned and transferred to a museum, like Gagarin's Start at Baikonur. As a result, Russia is temporarily unable to launch Soyuz crewed spacecraft and Progress cargo ships to the ISS, whose nearest launch (Progress MS-33) was scheduled for December 21.... When the rocket launched, a pressure difference was created between the space under the rocket, where gases from running engines are discharged, and the nook where the [144-ton] maintenance cabin was located. The resulting pressure difference pulled the service cabin out of the nook and threw it into the flame trench, where it fell upside down from a height of 20 m. Photos of the accident showed significant damage to the maintenance cabin, which, according to experts, is too extensive to allow for repairs. The only way to resume launches from Site 31/6 is to install a spare maintenance cabin or construct a new one. Despite the fact that the fallen structure was manufactured in the 1960s, two similar service cabins were manufactured recently at the Tyazhmash heavy-engineering plant in Syzran for other Soyuz launch complexes at the Guiana Space Center and Vostochny Cosmodrome. The production of each cabin took around two years to complete, however, it was not for an emergency situation. "Various experts gave different possible estimates of the recovery time of the Site 31 launch complex: from several months to three years."

- Windows drive letters are not limited to A-Z
On its own, the title of this post is just a true piece of trivia, verifiable with`the built-in`subst`tool`(among other methods). Heres an example creating the drive +:\ as an alias for a directory at C:\foo: The +:\ drive then works as normal (at least in cmd.exe, this will be discussed more later): However, understanding why its true elucidates a lot about how Windows works under the hood, and turns up a few curious behaviors. ↫ Ryan Liptak Fascinating doesnt even begin to describe this article, but at the same time, it also makes me wonder at what point maintaining this drive letter charade becomes too burdensome, clunky, and complex. Internally, Windows NT does not use drive letters at all, but for the sake of backwards compatibility and to give the user what they expect, a whole set of abstractions has been crafted to create the illusion that modern versions of Windows still use the same basic drive letter conventions as DOS did 40 years ago. I wonder if well ever reach a point where Windows no longer uses drive letters, or if its possible today to somehow remove or disable these abstractions entirely, and run Windows NT without drive letters, as Cutler surely intended. Vast swaths of Windows programs would surely curl up in fetal position and die, including many core components of the operating system itself as this article demonstrates, very few parts of Windows can handle even something as mundane as a drive letter outside of A-Z but itd make for a great experiment. Someone with just the right set of Windows NT skills mustve tried something like this at some point, either publicly or inside of Microsoft.
- Migrating Dillo away from GitHub
What do you do if you develop a lightweight browser that doesnt support JavaScript, but you once chose GitHub as the home for your code? Youre now in the unenviable position that your own browser can no longer access your own online source repository because it requires JavaScript, which is both annoying and, well, a little awkward. The solution is, of course, obvious: you move somewhere else. Thats exactly what the Dillo browser did. They set up a small VPS, opted for cgit as the git frontend for its performance and small size, and for the bug tracker, they created a brand new, very simple bug tracker. To avoid this problem, I created my own bug tracker software, buggy, which is a very simple C tool that parses plain Markdown files and creates a single HTML page for each bug. All bugs are stored in a git repository and a git hook regenerates the bug pages and the index on each new commit. As it is simply plain text, I can edit the bugs locally and only push them to the remote when I have Internet back, so it works nice offline. Also, as the output is just an static HTML site, I dont need to worry about having any vulnerabilities in my code, as it will only run at build time. ↫ Rodrigo Arias Mallo Theres more considerations detailed in the article about Dillos migration, and it can serve as inspiration for anyone else running a small open source project who wishes to leave GitHub behind. With GitHubs continuing to add more and more complexity and AI! to separate open source code from its licensing terms, we may see more and more projects giving GitHub the finger.
- Landlock-ing Linux
Landlock is a Linux API that lets applications explicitly declare which resources they are allowed to access. Its philosophy is similar to OpenBSD’s`unveil()`and (less so)`pledge(): programs can make a contract with the kernel stating, “I only need these files or resources — deny me everything else if I’m compromised.” It provides a simple, developer-friendly way to add defense-in-depth to applications. Compared to traditional Linux security mechanisms, Landlock is vastly easier to understand and integrate. This post is meant to be an accessible introduction, and hopefully persuade you to give Landlock a try. ↫ prizrak.me blog I had no idea this existed, even though it seems to plug a hole in the security and sandboxing landscape on Linux by not requiring any privileges and by being relatively simple and straightforward to use. Theres even an additional supervisor! proposal that would bring Android-like permissions not just to, say, desktop applications (see Flatpak), but to every process trying to access anything for the first time. Im not knowledgeable enough to make any statements about Landlock compared to any other options we have for securing desktop Linux in a user-friendly, non-intrusive manner, but I definitely like its simplicity.
- System 7 natively boots on the Mac Mini G4
Only a few weeks ago, the CHRP variants of Mac OS 7.6 and 8 were discovered and uploaded to the internet for posterity, but were already seeing the positive results of this event unfold: Mac OS 7.x can now run on the Mac Mini G4 natively. The very short of it is as follows. First, the CHRP release of Mac OS 8 contains a ROM file that allows Mac OS 8 to boot on the G4 Mac Mini. Second, the CHRP release of 7.6 contains a System Enabler that allows 7.6 earlier versions to run by using the aforementioned ROM file. Third, the ROM has been modified to add compatibility with as many Mac models as possible. Theres a lot more to it, of course, but the end result is that quite a few more older, pre-9.x versions of Mac OS can now run on G4 and G3 Macs, which is quite cool. Of course, there are limitations. Note that, although I describe many of these as stable!, I mean you can use much of it normally (sound/video/networking aside) without it crashing or misbehaving, at least not too hard, but that is not to say everything works, because that is just not the case. For example, when present, avoid opening the Apple System Profiler, unless you want a massive crash as it struggles trying to profile and gather all the information about your system. Some other apps or Control Panels might either not work, or work up to a certain point, after which they might freeze, requiring you to Force Quit the Finder to keep on going. And so on. ↫ Jubadub at Mac OS 9 Lives Issues or no, this is amazing news, and great work by all involved.
- Genode OS Framework 25.11 released
The release 25.11 wraps up our year of rigidity, clarity, performance! with a bouquet of vast under-the-hood improvements. Genodes custom kernel received special tuning of its new CPU scheduler for Sculpt-OS workloads, and became much more scalable with respect to virtual-memory management. Combined, those efforts visibly boost the performance of Sculpt OS on performance-starved hardware like the PinePhone or the i.MX8-based MNT Reform laptop. On account of improving clarity, our new configuration format now named human-inclined data (HID) proliferates throughout Genodes tooling. We are also happy to report that almost all Genode components have become interoperable with both XML and HID by now. ↫ Genode OS Framework 25.11 release notes The Genode Framework 25.11 also brings a major change to how important shared components that arent strictly part of the framework are handled, such as ports like libSDL, sqlite, or gnutls. Before, these could only be built with the Genode build system, which was suboptimal because this isnt designed for building individual components. Several changes have been made to now enable the use of multiple build systems and the Goa SDK, which should make it a lot easier to these crucial components to become the responsibility of wider parts of the community. Theres way more, of course, such as the usual driver improvements, including the addition of support for serial-to-USB adapters.
- Dell: about 1 billion PCs will not or cannot be upgraded to Windows 11
During a Dell earnings call, the company mentioned some staggering numbers regarding the amount of PCs that will not or cannot be upgraded to Windows 11. “We have about 500 million of them capable of running Windows 11 that haven’t been upgraded,” said Dell COO Jeffrey Clarke on a Q3 earnings call earlier this week, referring to the overall PC market, not just Dell’s slice of machines. “And we have another 500 million that are four years old that can’t run Windows 11.” He sees this as an opportunity to guide customers towards the latest Windows 11 machines and AI PCs, but warns that the PC market is going to be relatively flat next year. ↫ Tom Warren at The Verge The monumental scale of the Windows 10 install base that simply wont or cannot upgrade to Windows 11 is massive, and its absolutely bonkers to me that were mostly just letting them get away with leaving at least a billion users out in the cold when it comes to security updates and bug fixes. The US government (in better times) and the EU shouldve 100% forced Microsofts hand, as leaving this many people on outdated, unsupported operating system installations is several disasters waiting to happen. Aside from the dangerous position Microsoft is forcing its Windows 10 users into, theres also the massive environmental and public health impact of huge swaths of machines, especially in enterprise environments, becoming obsolete overnight. Many of these will end up in landfills, often shipped to third-world countries so we in the west dont have to deal with our e-waste and its dangerous consequences directly. I can get fined for littering rightfully so but when a company like Microsoft makes sweeping decisions which cause untold amounts of dangerous chemicals to be dumped in countless locations all over the globe, governments shrug it off and move on. At least we will get some cheap eBay hardware out of it, I guess.
- CDE 2.5.3 released
So my love for the Common Desktop Environment isnt exactly a secret, so lets talk about the projects latest release, CDE 2.5.3, released a few days ago. As the version number suggests, this first new version in two years is a rather minor release, containing only a few bug fixes. For instance, CDEs window manager dtwm picked up support for more mouse buttons, its file manager dtfile now uses sh to find files instead of ksh, and a few more of these rather minor, but welcome, changes and bugfixes. Ever since CDE was released as open source over thirteen years ago, and while considerable work has been done to make it build, install, and run on modern platforms, thats kind of where the steam ran out. CDE isnt being actively developed to build upon its strengths and add new and welcome features and conveniences, but is instead kept in a sort of buildable stasis. There is absolutely nothing wrong with this it keeps CDE accessible on modern platforms, and thats a huge amount of work that deserves respect and gratitude but itd be nice if we lived in a world where there was enough interest (and time and money) to have people work on actually improving it. Of course, the reality is that thered be very little interest in such an improved CDE, and thats exactly why it isnt happening. On top op the current work the CDE team is doing, youd need to not only develop new features, but also improve the Motif toolkit to make such new features possible, and make sure such improvements dont break anything else. With such an old codebase, that cant possible be an easy task. Still, I will continue to daydream of a slightly more modernised CDE with some additional niceties weve come to expect over the past 30 years, even if I know full well its futile.

- KDE to drop X11 session in KDE Plasma 6.8
The KDE project has made the call. Well folks, it’s the beginning of a new era: after nearly three decades of KDE desktop environments running on X11, the future KDE Plasma 6.8 release will be Wayland-exclusive! Support for X11 applications will be fully entrusted to Xwayland, and the Plasma X11 session will no longer be included. ↫ The Plasma Team Theyre following in the footsteps of the GNOME project, who will also be leaving the legacy windowing system behind. What this means in practice is that official KDE X11 support will cease once KDE Plasma 6.7 is no longer supported, which should be somewhere early 2027. Do note that the KDE developers intend to release a few extra bugfix releases in the 6.7 release cycle to stabilise the X11 session as much as possible for those people who are going to stick with KDE Plasma 6.7 to keep X11 around. For people who wish to keep using X11 after that point, the KDE project advises them to switch to LTS distributions like Alma Linux, which intend to keep supporting Plasma X11 until 2032. Xwayland will handle virtually all X11 applications running inside the Wayland session, including X11 forwarding, with similar functionality implemented in Wayland through Waypipe. Also note that this only applies to Plasma as a whole; KDE applications will continue to support X11 when run in other desktop environments or on other platforms. As for platforms other than Linux FreeBSD already has relatively robust Wayland support, so if you intend to run KDE on FreeBSD in the near future, youll have to move over to Wayland there, as well. The other BSD variants are also dabbling with Wayland support, so it wont be long before they, too, will be able to run the KDE Plasma Wayland session without any issues. What this means is that the two desktop environments that probably make up like 95% of the desktop Linux user base will now be focusing exclusively on Wayland, which is great news. X11 is a legacy platform and aside from retrocomputing and artisanal, boutique setups, you simply shouldnt be using it anymore. Less popular desktop environments like Xfce, Cinnamon, Budgie, and LXQt are also adding Wayland support, so it wont be much longer before virtually no new desktop Linux installations will be using X11. One X down, one more to go.
- Microsoft will start preloading Explorer because its so slow
With all the problems Windows is facing, I think one area where Microsoft can make some easy, quick gains is by drastically improving Explorer, Windows file manager. It seems that in the latest developer releases, theyre doing just that. The most impactful change possibly is that Microsoft is going to preload Explorer. We’re exploring preloading File Explorer in the background to help improve File Explorer launch performance. This shouldn’t be visible to you, outside of File Explorer hopefully launching faster when you need to use it. If you have the change, if needed there is an option you can uncheck to disable this called “Enable window preloading for faster launch times” in File Explorer’s Folder Options, under View. ↫ Windows Insider Program Team Microsoft is also reordering the context menu in Explorer, and while this may seem like a small set of changes, the new context menu does look much tidier and less busy. They achieve this by moving a few top-level items to a submenu, and reordering some other elements. Sadly, the context menu still retains its own context menu ( Show more options!), which is a traditional Win32 menu which I still think is one of the most Windows of Windows things of all time. Regardless, I hope these small changes make Explorer more bearable to use for those of you still using Windows, because we all know you need it.
- Googles Android for desktops and laptops is called Aluminium
Google has made it very clear that its intending to bring Android to laptops and desktops, and replace Chrome OS with Android in the process. We now have a codename, and some more information about what this will look like in practice. Over the weekend, a tipster on Telegram named Frost Core shared a link to an intriguing Google job listing for a ‘Senior Product Manager, Android, Laptop and Tablets.’ While we already know Google is bringing Android to the PC, the listing explicitly states that the role involves ‘working on a new Aluminium, Android-based, operating system.’ This effectively confirms that Aluminium is the codename for the new unified platform. The name appears to be a nod to the project’s roots: like Chromium (the open-source version of ChromeOS), Aluminium is a metal ending in ‘-ium.’ The choice of the British spelling — emphasizing the ‘Al’ prefix — likely pays homage to Android serving as the project’s foundation.” ↫ Mishaal Rahman at Android Authority So we have the codename, and of course, what we also have is a strong focus on AI!, which will be at the core! of desktop Android. Further details uncovered in job openings include a focus not just on entry-level hardware, but also midrange and premium laptops and desktops, as well as Chrome OS being replaced by this new desktop Android variant. I somehow doubt existing Chrome OS devices will be updated to this new desktop Android variant, so Chrome OS will continue to exist as a product for at least quite a few years to come. I still have a considerable amount of doubt that Google would be able to pull this off in a successful way. Its already hard enough to get anyone to buy any laptop that isnt running Windows or macOS, and I doubt the Android operating system has the kind of pull with consumers to make them consider switching to it on their laptops or desktops. Enthusiasts will surely eat it up if only to try but without any clear, massive success, this desktop Android thing runs the real risk of ending up at Googles graveyard. These Android laptops can be incredible products, but even if they are, I just wont trust Google to remain interested in it.
- Microsoft admits almost all major Windows 11 core features are broken
You may have noticed a sharp increase in problems and issues in Windows recently following the rise of the AI! hype cycle, entirely coincidentally, Im sure and it seems Microsoft is finally starting to acknowledge just how bad Windows has become. On the positive side though, following all that backlash, Microsoft acknowledged Windows has issues, and as if on cue, the company in a new support article has admitted that there are problems on almost every major Windows 11 core feature. The issues are related to XAML and this impacts all the Shell components like the Start Menu, Taskbar, Explorer, and Windows Settings. ↫ Sayan Sen at Neowin Its wild how many core components like this have apparently been broken due to these problems since July of this year. This means countless Windows users have been experiencing weird issues on a daily basis in multiple components for four months now, which is absolutely wild. On top of all the more structural problems in Windows, I wonder how people can get anything done at all only a few days ago, I had to manually clean out the Installer folder in the Windows folder on my wifes gaming PC, because for some inexplicable reason, Windows decided to permanently store 18GBs worth (!) of past Adobe Acrobat updates and installers in there. Its impossible to reliably say that Microsofts incessant focus on crypto NFTs AI! lies at the root of all of these problems, but if 30% of new! code in Microsoft is indeed regurgitated by AI!, its hard not to conclude as such.
- The privacy nightmare of browser fingerprinting
I suspect that many people who take an interest in Internet privacy don’t appreciate how hard it is to resist browser fingerprinting. Taking steps to reduce it leads to inconvenience and, with the present state of technology, even the most intrusive approaches are only partially effective. The data collected by fingerprinting is invisible to the user, and stored somewhere beyond the user’s reach. On the other hand, browser fingerprinting produces only statistical results, and usually can’t be used to track or identify a user with certainty. The data it collects has a relatively short lifespan – days to weeks, not months or years. While it probably can be used for sinister purposes, my main concern is that it supports the intrusive, out-of-control online advertising industry, which has made a wasteland of the Internet. ↫ Kevin Boone My view on this matter is probably a bit more extreme than some: I believe it should be illegal to track users for advertising purposes, because the data collected and the targeting it enables not only violate basic privacy rights enshrined in most constitutions, they also pose a massive danger in other ways. This very same targeting data is already being abused by totalitarian states to influence our politics, which has had disastrous results. Of course, our own democratic governments hands arent exactly clean either in this regard, as they increasingly want to use this data to stop terrorists! and otherwise infringe on basic rights. Finally, any time such data ends up on the black market after data breaches, criminals, organised or otherwise, also get their hands on it. I have no idea what such a ban should look like, or if its possible to do this even remotely effectively. In the current political climate in many western countries, which are dominated by the wealthy few and corporate interests, its highly unlikely that even if such a ban was passed as lip service to concerned constituents, any fines or other deterrents would probably be far too low to make a difference anyway. As such, my desire to have targeted online advertising banned is mostly theory, not practice further illustrated by the European Union caving like cowards on privacy to even the slightest bit of pressure. Best I can do for now is not partake in this advertising hellhole. I disabled and removed all advertising from OSNews recently, and have always strongly advised everyone to use as many adblocking options as possible. We not only have a Pi-Hole to keep all of our devices at home safe, but also use a second layer of on-device adblockers, and I advise everyone to do the same.
- Americans are holding onto devices longer than ever and it’s costing the economy!
We need to consume. The average American now holds onto their smartphone for 29 months, according to a`recent survey by Reviews.org, and that cycle is getting longer.

- Tuxedo cancels Snapdragon X Elite Linux laptop project
For the past 18 months, the Linux OEM Tuxedo Computers has been working on bringing a Snapdragon X Elite ARM laptop to market, but now they cancelled the project due to complications. Development turned out to be challenging due to the different architecture, and in the end, the first-generation X1E proved to be less suitable for Linux than expected. In particular, the long battery runtimes—usually one of the strong arguments for ARM devices—were not achieved under Linux. A viable approach for BIOS updates under Linux is also missing at this stage, as is fan control. Virtualization with KVM is not foreseeable on our model, nor are the high USB4 transfer rates. Video hardware decoding is technically possible, but most applications lack the necessary support. Given these conditions, investing several more months of development time does not seem sensible, as it is not foreseeable that all the features you can rightfully expect would be available in the end. In addition, we would be offering you a device with what would then be a more than two-year-old Snapdragon X Elite (X1E), whose successor, the Snapdragon X2 Elite (X2E), was officially introduced in September 2025 and is expected to become available in the first half of 2026. ↫ Tuxedos announcement Back when Qualcomm was hyping up these processors, the company made big claims about supporting Linux equally to Windows, but those promises have turned out to be absolutely worthless. Tuxedo already highlighted the problems it was dealing with half a year ago, and now it seems these problems have become impossible to overcome at least for now. This is a shame, bu also not entirely unexpected, since theres no way a small Linux OEM can do the work that Qualcomm promised it would do for its own chip. All this sadly means we still dont really have proper Linux support for modern ARM laptops, which is a crying shame. The problem isnt so much Linux itself, but the non-standardised world of ARM hardware. Large OEMs are willing to do the work to make Windows work, but despite recent successes, desktop Linux is nowhere near as popular as Windows, so theres little incentive for OEMs (or Qualcomm) to step up their game. It is what it is.
- Wine 10.19 Released: Game Changing Support for Windows Reparse Points on Linux
by George Whittaker Introduction
If you use Linux and occasionally run Windows applications, whether via native Wine or through gaming layers like Proton, you’ll appreciate what just dropped in Wine 10.19. Released November 14 2025, this version brings a major enhancement: official support for Windows reparse points, a filesystem feature many Windows apps rely on, and a host of other compatibility upgrades.
In simpler terms: Wine now understands more of the Windows filesystem semantics, which means fewer workarounds, better application compatibility, and smoother experiences for many games and tools previously finicky under Linux.
What Are Reparse Points & Why They MatterUnderstanding Reparse Points
On Windows, a reparse point is a filesystem object (file or directory) that carries additional data, often used for symbolic links, junctions, mount points, or other redirection features. When an application opens or queries a file, the OS may check the reparse tag to determine special behavior (for example “redirect this file open to this other path”).
Because many Windows apps, installers, games, DRM systems, file-managers, use reparse points for features like directory redirection, path abstractions, or filesystem overlays, lacking full support for them in Wine means those apps often misbehave.
What Wine 10.19 Adds
With Wine 10.19, support for these reparse point mechanisms has been implemented in key filesystem APIs: for example NtQueryDirectoryFile, GetFileInfo, file attribute tags, and DeleteFile/RemoveDirectory for reparse objects.
This means that in Wine 10.19:
Windows apps that create or manage symbolic links, directory junctions or mount-point style re-parsing will now function correctly in many more cases.
Installers or frameworks that rely on “when opening path X, redirect to path Y” will work with less tinkering.
Games or utilities that check for reparse tags or use directory redirections will have fewer “stuck” behaviors or missing files.
In effect, this is a step toward closer to native behavior for Windows file-system semantics under Linux.
Other Key Highlights in Wine 10.19
Beyond reparse points, the release brings several notable improvements:
Expanded support for WinRT exceptions (Windows Runtime error handling) meaning better compatibility for Universal Windows Platform (UWP) apps and newer Windows-based frameworks.
Refactoring of “Common Controls” (COMCTL32) following the version 5 vs version 6 split, which helps GUI applications that rely on older controls or expect mixed versions.

Mozilla has rolled out Firefox 145, a significant update that brings a range of usability, security and privacy enhancements, while marking a clear turning point by discontinuing official support for 32-bit Linux systems. For users on older hardware or legacy distros, this change means it’s time to consider moving to a 64-bit environment or opting for a supported version.
Here’s a detailed look at what’s new, what’s changed, and what you need to know.
Major Changes in Firefox 145End of 32-Bit Linux Builds
One of the headline items in this release is Mozilla’s decision to stop building and distributing Firefox for 32-bit x86 Linux. As per their announcement:
“32-bit Linux (on x86) is no longer widely supported by the vast majority of Linux distributions, and maintaining Firefox on this platform has become increasingly difficult and unreliable.”
From Firefox 145 onward, only 64-bit (x86_64) and relevant 64-bit architectures (such as ARM64) will be officially supported. For those still running 32-bit Linux builds, Mozilla recommends migrating to 64-bit or switching to the Extended Support Release (ESR) branch (Firefox 140 ESR) which still supports 32-bit for a limited period.
Usability & Interface Enhancements
Firefox 145 brings several improvements designed to make everyday web browsing smoother and more flexible:
PDF viewer enhancements: You can now add, edit, and delete comments in PDFs, and a comments sidebar helps you easily navigate your annotations.
Tab-group preview: When you hover over the name of a collapsed tab group, a thumbnail preview of the tabs inside appears, helpful for reorganizing or returning to work.
Access saved passwords from the sidebar, without needing to open a new tab or window.
“Open links from apps next to your active tab” setting: When enabled, links opened from external applications insert next to your current tab instead of at the end of the tab bar.
Slight UI refinements: Buttons, input fields, tabs and other elements get more rounded edges, horizontal tabs are redesigned to align with vertical-tab aesthetics.
Privacy, Security & Under-the-Hood Upgrades
Mozilla has also doubled down on privacy and risk reduction:
Fingerprinting defenses: Firefox 145 introduces new anti-fingerprinting techniques that Mozilla estimates reduce the number of users identified as unique by nearly half when Private Browsing mode or Enhanced Tracking Protection (strict) is used.

- MX Linux 25 ‘Infinity’ Arrives: Debian 13 ‘Trixie’ Base, Modern Tools & A Fresh Installer
by George Whittaker Introduction
The team behind MX Linux has just released version 25, carrying the codename “Infinity”, and it brings a significant upgrade by building upon the stable base of Debian 13 “Trixie”. Released on November 9, 2025, this edition doesn’t just refresh the desktop, it introduces modernized tooling, updated kernels, dual init-options, and installer enhancements aimed at both newcomers and long-time users.
In the sections that follow, we’ll walk through the key new features of MX Linux 25, what’s changed for each desktop edition, recommended upgrade or fresh-install paths, and why this release matters in the wider Linux-distribution ecosystem.
What’s New in MX Linux 25 “Infinity”
Here are the headline changes and improvements that define this release:
Debian 13 “Trixie” Base
By moving to Debian 13, Infinity inherits all the stability, security updates, and broader hardware support of the latest Debian stable release. The base system now aligns with Trixie’s libraries, kernels, and architecture support.
Kernel Choices & Hardware Support
The standard editions ship with the Linux 6.12 LTS kernel series, offering a solid baseline for most hardware.
For newer hardware or advanced users, the “AHS” (Advanced Hardware Support) variants and the KDE Plasma edition adopt a Liquorix-flavored Linux 6.16 (or 6.15 in some variants) kernel, maximizing performance and compatibility with cutting-edge setups.
Dual Init Option: systemd and SysVinit
Traditionally associated with lighter-weight init options, MX Linux now offers both systemd by default and SysVinit editions (particularly for Xfce and Fluxbox variants). This gives users the freedom to choose their init system preference without losing new features.
Updated Desktop Environments
Xfce edition: Ships with Xfce 4.20. Improvements include a revamped Whisker Menu, updated archive management tools (Engrampa replacing File Roller in some editions).
KDE Plasma edition: Uses KDE Plasma 6.3.6, defaults to Wayland for a modern session experience (with X11 still optionally available), adds root-actions and service menus to Dolphin, and switches TLP out for power-profiles-daemon to resolve power widget issues.
Fluxbox edition: Offers a more minimal, highly customizable environment: new panel layouts, updated “appfinder” configs for Rofi, toolbar changes and themes refined. Defaults the audio player to Audacious (instead of the older DeaDBeeF).

- Arch Linux November 2025 ISO: Fresh Snapshot, Smarter Installer (Archinstall 3.0.12) & Pacman 7.1
by George Whittaker
Arch Linux has shipped its November 2025 ISO snapshot (2025.11.01), and while Arch remains a rolling distribution, these monthly images are a big deal, especially for new installs, labs, and homelab deployments. This time, the ISO lands alongside two important pieces:
Archinstall 3.0.12 – a more polished, smarter TUI installer
Pacman 7.1 – a package manager update with stricter security and better tooling
If you’ve been thinking about spinning up a fresh Arch box, or you’re curious what changed under the hood, this release is a very nice jumping-on point.
Why Arch Still Ships Monthly ISOs in a Rolling World
Arch is famous for its “install once, update forever” model. Technically, you could install from a two-year-old image and just run:
sudo pacman -Syu
…but in practice, that’s painful:
Huge initial update downloads
Possible breakage jumping across many months of changes
Outdated installer tooling
That’s why the project publishes a monthly snapshot ISO: it rolls all current packages into a fresh image so you:
Start with a current kernel and userland
Spend less time updating right after install
Get the latest Archinstall baked in (or just a pacman -Sy archinstall away)
The 2025.11.01 ISO is exactly that: Arch as of early November 2025, ready to go.
What’s Inside the November 2025 ISO (2025.11.01)
The November snapshot doesn’t introduce new features by itself, it’s a frozen image of current Arch, but a few details are worth calling out:
Ships with a Linux 6.17.x kernel, including improved AMD/Intel GPU support and updated Btrfs bits.
Includes all the usual base packages plus current toolchains, drivers, and desktop stacks from the rolling repos.
The image is intended only for new installs; existing Arch systems should keep using pacman -Syu for upgrades.
You can download it from the official Arch Linux download page or via BitTorrent mirrors.
One small twist: the ISO itself still ships with Archinstall 3.0.11, but 3.0.12 was released the same day – so we’ll grab the newer version from the repos before running the installer.
Archinstall 3.0.12: What’s Actually New?
Archinstall has evolved from “nice experiment” to “pretty solid way to install Arch” if you don’t want to script everything yourself. Version 3.0.12 is a refinement release focused on stability, storage, and bootloader logic.

- AMD Confirms Zen 5 RNG Flaw: When ‘Random’ Isn’t Random Enough
by George Whittaker
AMD has officially confirmed a high-severity security vulnerability in its new Zen 5–based CPUs, and it’s a nasty one because it hits cryptography right at the source: the hardware random number generator.
Here’s a clear breakdown of what’s going on, how bad it really is, and what you should do if you’re running Zen 5.
What AMD Just Confirmed
AMD’s security bulletin AMD-SB-7055, now tracked as CVE-2025-62626, describes a bug in the RDSEED instruction on Zen 5 processors. Under certain conditions, the CPU can:
Return the value 0 from RDSEED far more often than true randomness would allow
Still signal “success” (carry flag CF=1), so software thinks it got a good random value
The issue affects the 16-bit and 32-bit forms of RDSEED on Zen 5; the 64-bit form is not affected.
Because RDSEED is used to feed cryptographically secure random number generators (CSPRNGs), a broken RDSEED can poison keys, tokens, and other security-critical values.
AMD classifies the impact as:
Loss of confidentiality and integrity (High severity).
How the Vulnerability Works (In Plain English)What RDSEED Is Supposed to Do
Modern CPUs expose hardware instructions like RDRAND and RDSEED:
RDRAND: Gives you pseudo-random values from a DRBG that’s already been seeded.
RDSEED: Gives you raw entropy samples suitable for seeding cryptographic PRNGs (it should be very close to truly random).
Software like TLS libraries, key generators, HSM emulators, and OS RNGs may rely directly or indirectly on RDSEED to bootstrap secure randomness.
What’s Going Wrong on Zen 5
On affected Zen 5 CPUs:
The 16-bit and 32-bit RDSEED variants sometimes return 0 much more often than a true random source should.
Even worse, they simultaneously report success (CF=1), so software assumes the value is fine rather than retrying.
In cryptographic terms, this means:
Entropy can be dramatically reduced (many key bits become predictable or even fixed).
Keys or nonces derived from those values can become partially or fully guessable.

- The Most Critical Linux Kernel Breaches of 2025 So Far
by George Whittaker
The Linux kernel, foundational for servers, desktops, embedded systems, and cloud infrastructure, has been under heightened scrutiny. Several vulnerabilities have been exploited in real-world attacks, targeting critical subsystems and isolation layers. In this article, we’ll walk through major examples, explain their significance, and offer actionable guidance for defenders.
CVE-2025-21756 – Use-After-Free in the vsock Subsystem
One of the most alarming flaws this year involves a use-after-free vulnerability in the Linux kernel’s vsock implementation (Virtual Socket), which enables communication between virtual machines and their hosts.
How the exploit works:A malicious actor inside a VM (or other privileged context) manipulates reference counters when a vsock transport is reassigned. The code ends up freeing a socket object while it’s still in use, enabling memory corruption and potentially root-level access.
Why it matters:Since vsock is used for VM-to-host and inter-VM communication, this flaw breaks a key isolation barrier. In multi-tenant cloud environments or container hosts that expose vsock endpoints, the impact can be severe.
Mitigation:Kernel maintainers have released patches. If your systems run hosts, hypervisors, or other environments where vsock is present, make sure the kernel is updated and virtualization subsystems are patched.
CVE-2025-38236 – Out-of-Bounds / Sandbox Escape via UNIX Domain Sockets
Another high-impact vulnerability involves the UNIX domain socket interface and the MSG_OOB flag. The bug was publicly detailed in August 2025 and is already in active discussion.
Attack scenario:A process running inside a sandbox (for example a browser renderer) can exploit MSG_OOB operations on a UNIX domain socket to trigger a use-after-free or out-of-bounds read/write. That allows leaking kernel pointers or memory and then chaining to full kernel privilege escalation.
Why it matters:This vulnerability is especially dangerous because it bridges from a low-privilege sandboxed process to kernel-level compromise. Many systems assume sandboxed code is safe; this attack undermines that assumption.
Mitigation:Distributions and vendors (like browser teams) have disabled or restricted MSG_OOB usage for sandboxed contexts. Kernel patches are available. Systems that run browser sandboxes or other sandboxed processes need to apply these updates immediately.
CVE-2025-38352 – TOCTOU Race Condition in POSIX CPU Timers
In September 2025, the U.S. Cybersecurity & Infrastructure Security Agency (CISA) added this vulnerability to its Known Exploited Vulnerabilities (KEV) catalog.

- Steam Deck 2 Rumors Ignite a New Era for Linux Gaming
by George Whittaker
The speculation around a successor to the Steam Deck has stirred renewed excitement, not just for a new handheld, but for what it signals in Linux-based gaming. With whispers of next-gen specs, deeper integration of SteamOS, and an evolving handheld PC ecosystem, these rumors are fueling broader hopes that Linux gaming is entering a more mature age. In this article we look at the existing rumors, how they tie into the Linux gaming landscape, why this matters, and what to watch.
What the Rumours Suggest
Although Valve has kept things quiet, multiple credible outlets report about the Steam Deck 2 being in development and potentially arriving well after 2026. Some of the key tid-bits:
Editorials note that Valve isn’t planning a mere spec refresh; it wants a “generational leap in compute without sacrificing battery life”.
A leaked hardware slide pointed to an AMD “Magnus”-class APU built on Zen 6 architecture being tied to next-gen handhelds, including speculation about the Steam Deck 2.
One hardware leaker (KeplerL2) cited a possible 2028 launch window for the Steam Deck 2, which would make it roughly 6 years after the original.
Valve’s own design leads have publicly stated that a refresh with only 20-30% more performance is “not meaningful enough”, implying they’re waiting for a more substantial upgrade.
In short: while nothing is official yet, there’s strong evidence that Valve is working on the next iteration and wants it to be a noteworthy jump, not just a minor update.
Why This Matters for Linux Gaming
The rumoured arrival of the Steam Deck 2 isn’t just about hardware, it reflects and could accelerate key inflection points for Linux & gaming:
Validation of SteamOS & Linux Gaming
The original Steam Deck, running SteamOS (a Linux-based OS), helped prove that PC gaming doesn’t always require Windows. A well-received successor would further validate Linux as a first-class gaming platform, not a niche alternative but a mainstream choice.
Handheld PC Ecosystem Momentum
Since the first Deck, many Windows-based handhelds have entered the market (such as the ROG Ally, Lenovo Legion Go). Rumours of the Deck 2 keep spotlight on the form factor and raise expectations for Linux-native handhelds. This momentum helps encourage driver, compatibility and OS investments from the broader community.

- VMScape: Cracking VM-Host Isolation in the Speculative Execution Age & How Linux Patches Respond
by George Whittaker Introduction
In the world of modern CPUs, speculative execution, where a processor guesses ahead on branches and executes instructions before the actual code path is confirmed, has long been recognized as a performance booster. However, it has also given rise to a class of vulnerabilities collectively known as “Spectre” attacks, where microarchitectural side states (such as the branch target buffer, caches, or predictor state) are mis-exploited to leak sensitive data.
Now, a new attack variant, dubbed VMScape, exposes a previously under-appreciated weakness: the isolation between a guest virtual machine and its host (or hypervisor) in the branch predictor domain. In simpler terms: a malicious VM can influence the CPU’s branch predictor in such a way that when control returns to the host, secrets in the host or hypervisor can be exposed. This has major implications for cloud security, virtualization environments, and kernel/hypervisor protections.
In this article we’ll walk through how VMScape works, the CPUs and environments it affects, how the Linux kernel and hypervisors are mitigating it, and what users, cloud operators and admins should know (and do).
What VMScape Is & Why It MattersThe Basics of Speculative Side-Channels
Speculative execution vulnerabilities like Spectre exploit the gap between architectural state (what the software sees as completed instructions) and microarchitectural state (what the CPU has done internally, such as cache loads, branch predictor updates, etc). Even when speculative paths are rolled back architecturally, side-effects in the microarchitecture can remain and be probed by attackers.
One of the original variants, Spectre-BTI (Branch Target Injection, also called Spectre v2) leveraged the Branch Target Buffer (BTB) / predictor to redirect speculative execution along attacker-controlled paths. Over time, hardware and software mitigations (IBRS, eIBRS, IBPB, STIBP) have been introduced. But VMScape shows that when virtualization enters the picture, the isolation assumptions break down.
VMScape: Guest to Host via Branch Predictor
VMScape (tracked as CVE‑2025‑40300) is described by researchers from ETH Zürich as “the first Spectre-based end-to-end exploit in which a malicious guest VM can leak arbitrary sensitive information from the host domain/hypervisor, without requiring host code modifications and in default configuration.”
Here are the key elements making VMScape significant:
The attack is cross-virtualization: a guest VM influences the host’s branch predictor state (not just within the guest).

- Self-Tuning Linux Kernels: How LLM-Driven Agents Are Reinventing Scheduler Policies
by George Whittaker Introduction
Modern computing systems rely heavily on operating-system schedulers to allocate CPU time fairly and efficiently. Yet many of these schedulers operate blindly with respect to the meaning of workloads: they cannot distinguish, for example, whether a task is latency-sensitive or batch-oriented. This mismatch, between application semantics and scheduler heuristics, is often referred to as the semantic gap.
A recent research framework called SchedCP aims to close that gap. By using autonomous LLM‐based agents, the system analyzes workload characteristics, selects or synthesizes custom scheduling policies, and safely deploys them into the kernel, without human intervention. This represents a meaningful step toward self-optimizing, application-aware kernels.
In this article we will explore what SchedCP is, how it works under the hood, the evidence of its effectiveness, real-world implications, and what caveats remain.
Why the Problem Matters
At the heart of the issue is that general-purpose schedulers (for example the Linux kernel’s default policy) assume broad fairness, rather than tailoring scheduling to what your application cares about. For instance:
A video-streaming service may care most about minimal tail latency.
A CI/CD build system may care most about throughput and job completion time.
A cloud analytics job may prefer maximum utilisation of cores with less concern for interactive responsiveness.
Traditional schedulers treat all tasks mostly the same, tuning knobs generically. As a result, systems often sacrifice optimisation opportunities. Some prior efforts have used reinforcement-learning techniques to tune scheduler parameters, but these approaches have limitations: slow convergence, limited generalisation, and weak reasoning about why a workload behaves as it does.
SchedCP starts from the observation that large language models can reason semantically about workloads (expressed in plain language or structured summaries), propose new scheduling strategies, and generate code via eBPF that is loaded into the kernel via the sched_ext interface. Thus, a custom scheduler (or modified policy) can be developed specifically for a given workload scenario, and in a self-service, automated way.
Architecture & Key Components
SchedCP comprises two primary subsystems: a control-plane framework and an agent loop that interacts with it. The framework decouples “what to optimise” (reasoning) from “how to act” (execution) in order to preserve kernel stability while enabling powerful optimisations.
Here are the major components:
