- Two new stable kernels
Greg Kroah-Hartman has announced the release of the 6.17.8 and 6.12.58 stable kernels. Each contains animportant set of fixes. Users are advised to upgrade.
- Rust in Android: move fast and fix things (Google Security Blog)
The Google Security Blog has anew post on just how well the use of Rust is working out for theAndroid project.
We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android's C and C++ code. But the biggest surprise was Rust's impact on software delivery. With Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one.
- Privilege escalation in LightDM Greeter by KDE (SUSE Security Team Blog)
The SUSE Security Team has published an in-deptharticle on its findings after reviewing a D-Bus service containedin LightDMGreeter by KDE (the lightdm-kde-greeter package)for addition to openSUSE Tumbleweed. The team found a privilegeescalation from the lightdm service user to root, aswell as other attack vectors in the service:
In agreement with upstream, we assigned CVE-2025-62876 to track thelightdm service user to root privilege escalation aspect described inthis report. The severity of the issue is low, since it only affectsdefense-in-depth (if the lightdm service user were compromised) andthe problematic logic can only be reached and exploited if triggeredinteractively by a privileged user.
The fixes are contained in the 6.0.4release of the project.
- Thunderbird 145 released
Version145 of the Thunderbird email client has been released. Notablechanges in this release include enabling DNS over HTTPS, support forMicrosoft Exchange via Exchange Web Services, and quite a few bugfixes. As of 145, the project is no longer shipping 32-bit binariesfor Linux on x86.
- [$] Another Fedora Flatpak discussion
Many distributions provide support out of the proverbial box forFlatpak packages, but Fedora is unusual in that it also provides, anddefaults, to its own repository of Fedora-built Flatpaks. This has beena source of confusion for Fedora users, who expect to get the Flatpakbuilt by the original developers and hosted on Flathub. It has also been a sourceof conflict with upstream projects, because users complain of bugs inFlatpak packages they are not responsible for. The situation has also frustrated someFedora developers, who would prefer to offer put Flathub's offeringsfirst. A new complaint that Fedora has apparently used manifestsfrom Flathub to build the packages for Fedora—without giving credit tothe original authors—has spurred discussions about Fedora'sFlatpaks once again. While no concrete changes are on the table, yet,there may be some movement toward addressing persistent complaints.
- Security updates for Thursday
Security updates have been issued by Debian (chromium and firefox-esr), Fedora (firefox, rubygem-rack, skopeo, and webkitgtk), Mageia (perl, perl-CPAN, perl-HTTP-Tiny, perl-Data-Entropy, perl-FCGI, perl-File-Find-Rule, perl-YAML-LibYAML, python-tornado, python-urllib3, python-pip, python3, and unbound), Oracle (ipa and kernel), Red Hat (container-tools:rhel8, krb5, openssl, pcs, podman, and runc), Slackware (mozilla), SUSE (binutils, kernel, netty, netty-tcnative, podman, python311-pdfminer, and tomcat11), and Ubuntu (bind9 and linux-aws-6.8).

Version5.0.0 of the Homebrew packagemanager for Linux and macOS has been released. Notable changes in thisrelease include download concurrency by default, official support for64-bit Arm on Linux, and more.
- [$] The intersection of unstable pages and direct I/O
Longtime LWN readers will have encountered the concept of "stable pages"before; it was first covered here nearly15 years ago. For the most part, the problem that stable pages weremeant to solve — preventing errors when user space modifies a buffer thatis under I/O — has been dealt with. Butrecent discussions show that there is one area where problems remain:direct I/O. There is some disagreement,though, over whether those problems are the result of user-space bugs andhow much of a performance price should be paid to address them.
- Security updates for Wednesday
Security updates have been issued by AlmaLinux (kernel, kernel-rt, and libtiff), Debian (kernel, libarchive, rust-sudo-rs, and squid), Fedora (chromium, dotnet8.0, forgejo, ruby, and webkitgtk), Oracle (bind, bind9.18, kernel, kernel-uek*, libtiff, and runc), Red Hat (firefox, kernel, and kernel-rt), Slackware (mozilla), SUSE (buildah, colord, containerd, kernel, lasso, libsoup, micropython, ongres-scram, openssh, proxy-helm, uyuni-tools, python-pdfminer.six, qatengine, qatlib, regclient, and runc), and Ubuntu (raptor and raptor2).
- World Still On Track For Catastrophic 2.6C Temperature Rise, Report Finds
An anonymous reader quotes a report from the Guardian: The world is still on track for a catastrophic 2.6C increase in temperature as countries have not made sufficiently strong climate pledges, while emissions from fossil fuels have hit a record high, two major reports have found. Despite their promises, governments' new emission-cutting plans submitted for the Cop30 climate talks taking place in Brazil have done little to avert dangerous global heating for the fourth consecutive year, according to the Climate Action Tracker update (PDF). The world is now anticipated to heat up by 2.6C above preindustrial times by the end of the century -- the same temperature rise forecast last year. This level of heating easily breaches the thresholds set out in the Paris climate pact, which every country agreed to, and would set the world spiraling into a catastrophic new era of extreme weather and severe hardships. A separate report found the fossil fuel emissions driving the climate crisis will rise by about 1% this year to hit a record high, but that the rate of rise has more than halved in recent years. The past decade has seen emissions from coal, oil and gas rise by 0.8% a year compared with 2.0% a year during the decade before. The accelerating rollout of renewable energy is now close to supplying the annual rise in the world's demand for energy, but has yet to surpass it. [...] The new analyses also show a worrying weakening of the planet's natural carbon sinks. The scientists said the combined effects of global heating and the felling of trees have turned tropical forests in southeast Asia and large parts of South America from overall CO2 sinks into sources of the climate-heating gas. [...] The report projects that the level of CO2 in the atmosphere will reach 425ppm (parts per million) in 2025, compared with 280ppm in the preindustrial era. It would have been 8ppm lower if the carbon sinks had not been weakened. The GCP projection for 2025 is based on monthly data up to September and has proven accurate in the previous 19 annual reports.

- Netflix's New Era of TV Games Starts Now
Netflix is launching a new slate of TV-streamed party games that are all playable using your phone as the controller. The Verge reports: To start, Netflix is offering Boggle Party, Party Crasher: Fool Your Friends, Lego Party, Pictionary: Game Night, and Tetris Time Warp. A social deduction game based on the Knives Out series, Dead Man's Party: A Knives Out Game, is also part of this new slate but will launch at a later time. The streaming platform's approach to gaming has been unfocused, with the company bouncing between being a boutique development studio while also being a platform for premium and exclusive mobile gaming experiences. Offering party games on your TV seems like a better fit -- one that could allow Netflix to finally find its gaming footing.

- Jack Dorsey Funds diVine, a Vine Reboot That Includes Vine's Video Archive
An anonymous reader quotes a report from TechCrunch: As generative AI content starts to fill our social apps, a project to bring back Vine's six-second looping videos is launching with Twitter co-founder Jack Dorsey's backing. On Thursday, a new app called diVine will give access to more than 100,000 archived Vine videos, restored from an older backup that was created before Vine's shutdown. The app won't just exist as a walk down memory lane; it will also allow users to create profiles and upload their own new Vine videos. However, unlike on traditional social media, where AI content is often haphazardly labeled, diVine will flag suspected generative AI content and prevent it from being posted. According to TechCrunch, a volunteer preservation group called the Archive Team saved Vine's content when it shut down in 2016. The only problem was that everything was stored in massive 40-50 GB binary blob files that were basically unusable for casual viewing. Evan Henshaw-Plath (who goes by the name Rabble), an early Twitter employee and member of Jack Dorsey's nonprofit "and Other Stuff," dug into those backup files to try and salvage as much as he could. He spent months writing big-data extraction scripts, reverse-engineering how the archived binaries were structured, and reconstructing the original video files, old user info, view counts, and more. "I wasn't able to get all of them out, but I was able to get a lot out and basically reconstruct these Vines and these Vine users, and give each person a new user [profile] on this open network," he said. Rabble estimates that through this process he was able to successfully recover 150,000-200,000 Vine videos from around 60,000 creators. diVine then rebuilt user profiles on top of the decentralized Nostr protocol so creators can reclaim their accounts, request takedowns, or upload missing videos. You can check out the app for yourself at diVine.video. It's available in beta form on both iOS and Android.

- Apple Cuts App Store Fee In Half For 'Mini Apps'
Apple is cutting its App Store fee from 30% to 15% for developers who join a new Mini Apps Partner Program, which requires using more of Apple's built-in technology to power lightweight "mini apps." "This includes using Apple software to register a user's purchase history, verify user ages and to process in-app purchases," reports CNBC. From the report: A "mini app" is a lightweight piece of software inside a third-party app store, like that of Discord's. These apps uses are built using web technology like HTML or Javascript. [...] Apple has argued that both developers and users are better off when using its technology and rules, instead of eschewing them to try to avoid fees. "This program is designed to help developers who host mini apps grow their business and further the availability of mini apps on the App Store -- all while providing a great customer experience," the company said in its announcement. [...] Participants in the new program will still have to provide Apple with information for each specific mini-app experience they offer.

- LinkedIn Is Making It Easier To Search For People With AI
LinkedIn is rolling out an AI-powered people search tool that lets users find connections by describing what they need instead of relying on names or titles. For example, you can enter a more descriptive search, such as "Northwestern alumni who work in entertaining marketing," or even pose a question, like "Who can help me understand the US work visa system." The Verge reports: LinkedIn senior director of product management Rohan Rajiv tells The Verge that the platform will rank results based on the connections you might have with someone, as well as their relevance to your search. [...] LinkedIn is rolling out AI-powered people search to Premium users in the US starting today, but the platform plans on bringing it to all users soon.

- Blue Origin Sticks First New Glenn Rocket Landing and Launches NASA Spacecraft
An anonymous reader quotes a report from TechCrunch: Jeff Bezos' Blue Origin has landed the booster of its New Glenn mega-rocket on a drone ship in the Atlantic Ocean on just its second attempt -- making it the second company to perform such a feat, following Elon Musk's SpaceX. It's an accomplishment that will help the new rocket system become an option to send larger payloads to space, the Moon, and beyond. Thursday's launch wasn't just about the landing attempt, though. Roughly 34 minutes after takeoff, the upper stage of New Glenn successfully deployed the rocket's first commercial payload: twin spacecraft for NASA that will travel to Mars to study the red planet's atmosphere. The pair of achievements are remarkable for the second-ever launch of such a massive rocket system. And it could put Blue Origin in position to compete with SpaceX, which dominates the world's launch market with its Falcon 9, Falcon Heavy, and Starship rockets. You can watch a recording of the launch here.

- Germany To Ban Huawei From Future 6G Network in Sovereignty Push
German Chancellor Friedrich Merz said Chinese suppliers such as Huawei will be excluded from the country's future telecommunication networks on security grounds as he pushes for more digital sovereignty. From a report: "We have decided within the government that everywhere it's possible we'll replace components, for example in the 5G network, with components we have produced ourselves," Merz told a business conference in Berlin on Thursday. "And we won't allow any components from China in the 6G network." Europe is increasingly concerned about its reliance on foreign technology, ranging from Asian semiconductors to US artificial intelligence and cloud infrastructure, as trade and geopolitical tensions threaten critical supply chains. Germany last year ordered telecom operators to remove Huawei equipment from their core networks, citing risks to national security. Berlin is now considering using public funds to pay Deutsche Telekom AG and others to strip out Chinese gear, Bloomberg News reported last month.

- China Plans To Limit How Fast Your Car Accelerates To 62 MPH At Startup
bobthesungeek76036 writes: Beijing's proposed regulation aims to tame rapid launches by forcing cars to boot up in a restricted performance mode after every ignition. Under a proposed update to the National Standard, every passenger car would need a default mode in which it takes no less than five seconds to reach 100 km/h (62 mph) at startup, unless the driver manually selects a quicker setting. The draft title "Technical Specifications for Power-Driven Vehicles Operating on Roads" appears to be part of a broader safety and road behavior initiative in China. It is intended to replace the current GB 7258-2017 standard that didn't impose such restrictions.

- Google cancels plans to require Android application certification outside of the Play Store
Only a few months ago, Google announced it was going to require that all Android applications even those installed outside of the Play Store had to be verified. This led to a massive backlash, and it seems our protests and complaints have had effect: the company announced a change in plans today, and will, in fact, not require certification for installing applications outside of the Play Store. Based on this feedback and our ongoing conversations with the community, we are building a new advanced flow that allows experienced users to accept the risks of installing software that isnt verified. We are designing this flow specifically to resist coercion, ensuring that users arent tricked into bypassing these safety checks while under pressure from a scammer. It will also include clear warnings to ensure users fully understand the risks involved, but ultimately, it puts the choice in their hands. We are gathering early feedback on the design of this feature now and will share more details in the coming months. ↫ Matthew Forsythe Director at the Android Developers Blog While this is great news, Im still concerned this is only temporary. Companies like Google have a tendency to announce some draconian measure to test the waters, walk it back in response to backlash, only to then reintroduce it through some sneaky backdoor a year later when nobodys looking. Installing whatever we want on the devices we own should be a protected right, not something graciously afforded to us by our corporate overlords. If you think this is the end of this story, youre a fool.

- Valve brings x86 gaming to ARM Linux with FEX
Valve announced a few new devices yesterday. Theres a new Steam console, which is essentially just a tiny PC with SteamOS installed think of it as a Steam Deck without a display. Second, Valve finally released a new Steam Controller to go with the Steam console, which has taken them long enough. Lastly, theres a brand new Steam VR headset, the Steam Frame. Other websites with actual access to these new devices will do a better job of covering them than I ever could, but I do want to highlight something crucially important about the Steam Frame: it contains a Snapdragon ARM processor, but can still run Steam and all of its games. How does this work? Well, after developing Proton to allow Windows games to run on Linux, Valve introduced! FEX, which will allow you to run x86 Windows games on ARM Linux. I put the quotation marks there because FEX was an existing project Valve invested heavily into in recent times, and its now at the point where Valve seems confident enough it will be capable of running enough x86 games on ARM Linux. As such, the Steam Frame runs full SteamOS with KDE Plasma, you can run x86 Steam games, and as an additional bonus, you can install Android APKs as well. Ive yet to even try VR, because Im not particularly interested in buying into any locked-down platform. The Steam Frame may be the first VR device Ill buy depending on price, of course and the Steam console definitely looks like a great addition to the living room, too. My wife and I have little to no interesting in buying an Xbox or PS5, but having easy, no-hassle access to our massive Steam libraries on our TV will be awesome.
- VMS/XDE: an OpenVMS x86 development environment for Linux and Windows/WSL
VMS/XDE is an OpenVMS x86 development environment for Linux and WIndows (via WSL). It provides a familiar user experience for OpenVMS developers working in Linux and Windows yet offers 100% binary and file system compatilibilty with OpenVMS. VMS/XDE includes OpenVMS V9.2-3 user, supervisor and executive mode operating system environments and a set of x86 native compilers and layered products geared towards OpenVMS software development and testing. ↫ VMS/XDE website VMS/XDE is a beta version, and comes with the usual annoying OpenVMS x86 time bombs, this time exploding on 3 January 2026. If you intend to use the finalised commercial version after the beta period ends, youll have to employ the same licenses as regular OpenVMS. Its a bit of a mess, but thats the OpenVMS way, sadly and I dont blame them, either, as Im sure theyre hamstrung by a ton of agreements and restrictions imposed upon them by HP. Regardless, VMS/XDE brings a zero setup OpenVMS environment to the operating system youre already using, making it easier to develop and cross-compile for the platform. I still have absolutely no clue just how many people OpenVMS is still relevant for, but I absolutely adore the fact VMS Software Inc. is working on this. In a world where so many of its former competitors are being held hostage by corporate indifference, its refreshing to see VMS still moving forward.
- Plasma Mobile 6.5 keeps improving
As part of the KDE Plasma 6.5 release, we also got a new release of Plasma Mobile. As theres a lot of changes, improvements, and new features in Plasma Mobile 6.5, the Plasma Mobile Team published a blog post to highlight them all. The biggest improvement is probably the further integration of Waydroid, a necessary evil to run Android applications until the Plasma Mobile ecosystem manages to become a bit more well-rounded. Waydroid can now be managed straight from the settings application and the quick settings dropdown. Furthermore, the lockscreen has been improved considerably, theres been a ton of polish for the home screen and the user interface in general, the quick settings panel can now be customised to make it fit better on different form factors, the first early test version of the new Plasma mobile keyboard is included, and so much more. This is definitely a release I would want to try out, but since I dont have any of the supported devices, Im a bit stuck. This is, of course, one of the two major problems facing proper mobile Linux: the lack of device support. Its improving due to the tireless work of countless volunteers, but theyre always going to be swimming upstream. The other major problem is, of course, application availability, but at least Waydroid can bridge the gap for the adventurous among us.
- Tribblix m38 released
Tribblix, the Illumos distribution focused on giving you a classic UNIX-style experience, has released a new version. Milestone 38 isnt the most consequential release of all time, but it does bring a few small changes accompanied by the usual long list of updated open source packages. The zap install command now installs dependencies by default, while zap create-user will now restrict new home directories to mode 0700 by default. Meanwhile, int16h at Cryogenix published an article about using a Bhyve VM running FreeBSD to act as a Wi-Fi bridge for laptops with 802.11xx chips that Tribblix doesnt support. This is a great, albeit somewhat convoluted option if your hardware uses any Wi-Fi chips Tribblix doesnt support. Theres honestly a solution for everything, isnt there?
- Setting up a combined 68k/PA-RISC HP-UX 9 cluster
Jonathan Pallant got lucky and managed to score a massive haul of 90s UNIX workstations, one of which was an HP 9000 Model 340, a HP-UX workstation built around a Motorola 68030 processor at 16.7 MHz. It doesnt come with a hard drive or even a floppy controller, though, so he decided to borrow a PA-RISC-based HP 9000 Model 705 to set up an HP-UX 9 cluster. But wait, how does that work, when were dealing with two entirely different architectures? Whats more fun though, is putting it into a cluster with the Model 705 and network booting it. Yes, that a 68030 machine network booting from a PA-RISC machine 0 and`sharing the same root filesystem. But arent PA-RISC binaries and 68K binaries quite different? Oh yes, they really are. So, how does that work? ↫ Jonathan Pallant HP-UX is far more interesting and fascinating than a lot of people give it credit for, and while my interest lies with HP-UX 11i, I find what Pallant is doing here with HP-UX 9 just as fascinating. You first need to install HP-UX 9 for PA-RISC on the 700 series machine, convert it to a cluster server, and then install HP-UX 9 for 68k on top of that PA-RISC installation. After this is done, you effectively end up with a single root file system that contains both PA-RISC and 68k binaries, and you can network boot the 68k-based Model 340 right from it using the same root filesystem on both machines. Absolutely wild. No, these are not universal binaries or some other trick you might know of from more modern system. In fact, installing the 68k version of HP-UX 9 into! the PA-RISC HP-UX 9 cluster server, you end up with something called a Context Dependent Filesystem. To get a better idea of what this means and how this works, you should really head on over to Pallants excellent article for all the details.
- Ironclad 0.7.0 and 0.8.0 released, adds RISC-V support
Weve talked about Ironclad a few times, but theres been two new releases since the 0.6.0 release we covered last, so lets see what the projects been up to. As a refresher, Ironclad is a formally verified, hard real-time capable kernel written in SPARK and Ada. Versions 0.7.0 and 0.8.0 improved support for block device caching, added a basic NVMe driver, added support for x86’s SMAP, switched from KVM to NVMM for Ironclad’s virtualization interface, and much, much more. In the meantime, Ironclad also added support for RISC-V, making it usable on any 64 bit RISC-V target that supports a Limine-protocol compatible bootloader. The easiest way to try out Ironclad is to download Gloire, a distribution that uses Ironclad and the GNU tools. It can be installed in both a virtual machine and on real hardware.
- Mac OS 7.6 and 8 for CHRP releases discovered
For those of us unaware unlikely on OSNews, but still for a hot minute in the second half of the 90s, Apple licensed its Mac OS to OEMs, resulting in officially sanctioned Mac clones from a variety of companies. While intended to grow the Macs market share, what ended up happening instead is that the clone makers outcompeted Apple on performance, price, and features, with clones offering several features and capabilities before Apple did for far lower prices. When Steve Jobs returned to Apple, he killed the clone program almost instantly. The rather abrupt end of the clone program means theres a number of variants of the Mac OS that never made their way into the market, most notable variants intended for the Common Reference Hardware Platform, or CHRP, a standard defined by IBM and Apple for PowerPC-based PCs. Thanks to the popular classic Mac YouTuber Mac84, we now have a few of these releases out in the wild. These CDs contain release candidates for Mac OS 7.6 and Mac OS 8 for CHRP (Common Hardware Reference Platform) systems. They were created to support CHRP computers, but were never released, likely due to Steve Jobs returning to Apple in September 1997 and eliminating the Mac Clone program and any CHRP efforts. ↫ Mac OS 7.6/8 CHRP releases page Mac84 has an accompanying video diving into more detail about these individual releases by booting and running them in an emulator, so we can get a better idea of what they contain. While most clone makers only got access to Mac OS 7.x, some of them did, in fact, gain access to Mac OS 8, namely UMAX and Power Computing (the latter of which was acquired by Apple). Its not the clone nature of these releases that make them special, but the fact theyre CHRP releases is. This reference platform was a failure in the market, and only a few of IBMs own machines and some of Motorolas PowerStack machines properly supported it. Apple, meanwhile, only aid minor lip service to CHRP in its New World Power Macintosch machines.
- FreeBSD now builds reproducibly and without root privilege
The FreeBSD Foundation is pleased to announce that it has completed work to build FreeBSD without requiring root privilege. We have implemented support for all source release builds to use no-root infrastructure, eliminating the need for root privileges across the FreeBSD release pipeline. This work was completed as part of the`program commissioned by the Sovereign Tech Agency. ↫ FreeBSD Foundation blog This is great news in and of itself, but theres more: FreeBSD has also improved build reproducability. This means that given the same source input, you should end up with the same binary output, which is an important part of building a verifiable chain of trust. These two improvements combined further add to making FreeBSD a trustworthy, secure option something it already is anyway. In case you havent noticed, the FreeBSD project and its countless contributors are making a ton of tangible progress lately on a wide variety of topics, from improving desktop use, to solidifying Wi-Fi support, to improving the chain of trust. I think the time is quite right for FreeBSD to make some inroads in the desktop UNIX-y space, especially for people to whom desktop Linux has strayed too far from the traditional UNIX philosphy (whatever that means).
- 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:

- Bcachefs Ousted from Mainline Kernel: The Move to DKMS and What It Means
by George Whittaker Introduction
After years of debate and development, bcachefs—a modern copy-on-write filesystem once merged into the Linux kernel—is being removed from mainline. As of kernel 6.17, the in-kernel implementation has been excised, and future use is expected via an out-of-tree DKMS module. This marks a turning point for the bcachefs project, raising questions about its stability, adoption, and relationship with the kernel development community.
In this article, we’ll explore the background of bcachefs, the sequence of events leading to its removal, the technical and community dynamics involved, and implications for users, distributions, and the filesystem’s future.
What Is Bcachefs?
Before diving into the removal, let’s recap what bcachefs is and why it attracted attention.
Origin & goals: Developed by Kent Overstreet, bcachefs emerged from ideas in the earlier bcache project (a block-device caching layer). It aimed to build a full-featured, general-purpose filesystem combining performance, reliability, and modern features (snapshots, compression, encryption) in a coherent design.
Mainline inclusion: Bcachefs was merged into the mainline kernel in version 6.7 (released January 2024) after a lengthy review and incubation period.
“Experimental” classification: Even after being part of the kernel, bcachefs always carried disclaimers about its maturity and stability—they were not necessarily recommends for production use by all users.
Its presence in mainline gave distributions a path to ship it more casually, and users had easier access without building external modules—an important convenience for adoption.
What Led to the Removal
The excision of bcachefs from the kernel was not sudden but the culmination of tension over development practices, patch acceptance timing, and upstream policy norms.
“Externally Maintained” status in 6.17
In kernel 6.17’s preparation, maintainers marked bcachefs as “externally maintained.” Though the code remained present, the change signified that upstream would no longer accept new patches or updates within the kernel tree.
This move allowed a transitional period. The code was “frozen” inside the tree to avoid breaking existing systems immediately, while preparation was made for future removal.

- Linux Mint 22.2 ‘Zara’ Released: Polished, Modern, and Built for Longevity
by George Whittaker Introduction
The Linux Mint team has officially unveiled Linux Mint 22.2, codenamed “Zara”, on September 4, 2025. As a Long-Term Support (LTS) release, Zara will receive updates through 2029, promising users stability, incremental improvements, and a comfortable desktop experience.
This version is not about flashy overhauls; rather, it’s about refinement — applying polish to existing features, smoothing rough edges, weaving in new conveniences (like fingerprint login), and improving compatibility with modern hardware. Below, we’ll delve into what’s new in Zara, what users should know before upgrading, and how it continues Mint’s philosophy of combining usability, reliability, and elegance.
What’s New in Linux Mint 22.2 “Zara”
Here’s a breakdown of key changes, refinements, and enhancements in Zara.
Base, Support & Kernel Stack
Ubuntu 24.04 (Noble) base: Zara continues to use Ubuntu 24.04 as its upstream base, ensuring broad package compatibility and long-term security support.
Kernel 6.14 (HWE): The default kernel for new installations is 6.14, bringing support for newer hardware.
However — for existing systems upgraded from Mint 22 or 22.1 — the older kernel (6.8 LTS) remains the default, because 6.14’s support window is shorter.
Zara is an LTS edition, with security updates and maintenance promised through 2029.
Major Features & EnhancementsFingerprint Authentication via Fingwit
Zara introduces a first-party tool called Fingwit to manage fingerprint-based authentication. With compatible hardware and support via the libfprint framework, users can:
Enroll fingerprints
Use fingerprint login for the screensaver
Authenticate sudo commands
Launch administrative tools via pkexec using the fingerprint
In some cases, bypass password entry at login (unless home directory encryption or keyring constraints force password fallback)
It is important to note that fingerprint login on the actual login screen may be disabled or limited depending on encryption or keyring usage; in those cases, the system falls back to password entry.
UI & Theming Refinements
Sticky Notes app now sports rounded corners, improved Wayland compatibility, and a companion Android app named StyncyNotes (available via F-Droid) to sync notes across devices.

- Ubuntu Update Backlog: How a Brief Canonical Outage Cascaded into Multi-Day Delays
by George Whittaker Introduction
In early September 2025, Ubuntu users globally experienced disruptive delays in installing updates and new packages. What seemed like a fleeting outage—only about 36 minutes of server downtime—triggered a cascade of effects: mirrors lagging, queued requests overflowing, and installations hanging for days. The incident exposed how fragile parts of Ubuntu’s update infrastructure can be under sudden load.
In this article, we’ll walk through what happened, why the fallout was so severe, how Canonical responded, and lessons for users and infrastructure architects alike.
What Happened: Outage & Immediate Impact
On September 5, 2025, Canonical’s archive servers—specifically archive.ubuntu.com and security.ubuntu.com—suffered an unplanned outage. The status page for Canonical showed the incident lasting roughly 36 minutes, after which operations were declared “resolved.”
However, that brief disruption set off a domino effect. Because the archives and security servers serve as the central hubs for Ubuntu’s package ecosystem, any downtime causes massive backlog among mirror servers and client requests. Mirrors found themselves out of sync, processing queues piled up, and users attempting updates or new installs encountered failed downloads, hung operations, or “404 / package not found” errors.
On Ubuntu’s community forums, Canonical acknowledged that while the server outage was short, the upload / processing queue for security and repository updates had become “obscenely” backlogged. Users were urged to be patient, as there was no immediate workaround.
Throughout September 5–7, users continued reporting incomplete or failed updates, slow mirror responses, and installations freezing mid-process. Even newly provisioning systems faced broken repos due to inconsistent mirror states.
By September 8, the situation largely stabilized: mirrors caught up, package availability resumed, and normal update flows returned. But the extended period of degraded service had already left many users frustrated.
Why a Short Outage Turned into Days of Disruption
At first blush, 36 minutes seems trivial. Why did it have such prolonged consequences? Several factors contributed:
Centralized repository backplane Ubuntu’s infrastructure is architected around central canonical repositories (archive, security) which then propagate to mirrors worldwide. When the central system is unavailable, mirrors stop receiving updates and become stale.
