About this tag
The linux kernel tag on WindowsForum.com covers recent kernel security fixes and development changes relevant to Linux systems, with a focus on how they differ from Windows. Recent threads detail CVE patches for AMDGPU, Nouveau, ath6kl Wi-Fi, NZXT Smart Device, Corsair Commander Pro, and Arm FF-A drivers, emphasizing that these are Linux-specific issues, not Windows vulnerabilities. The tag also includes coverage of Linux 7.2 dropping TSC-less x86 support and ending i486 kernel compatibility. Content is aimed at administrators and enthusiasts who need to understand which kernel updates to apply and why, often clarifying that Windows installations are unaffected by these particular flaws.

    How Git Began: BitKeeper License Dispute, Linux Kernel Migration and GitHub Timeline

    Git is the foundation of nearly every modern development workflow, and its origin is a dispute over a licence. In April 2005, BitMover withdrew the free-of-charge BitKeeper arrangement that the Linux kernel community relied on. Linus Torvalds then wrote a replacement. It is worth retelling...

    NVIDIA Nova Rust Driver Targets Open RM Replacement, but Desktop Support Is Years Away

    Nova, the Rust-based NVIDIA kernel driver being built upstream in Linux, used to be a Nouveau successor with a vague long-term hope attached. After this week's Linux Plumbers Conference (LPC) in Prague, it looks more like a plan to replace NVIDIA's own open kernel modules. It is still not a...

    Linux Arm64 Kernel Patch Cuts x86 Atomic Fault Handling Over 5x for FEX and Proton

    Igalia's André Almeida has put a number on what it costs to emulate x86 atomics on Arm64 in userspace. His figure is "more than 5x" in favor of the kernel. It is a narrow, fault-handling result, so it needs careful reading. The talk, "Emulating x86 atomics on arm64," was given at Linux Plumbers...

    Branch Target Reuse Spectre v2 Flaw Hits JIT Engines: Linux Kernel Fixes for CVE-2026-64507/64508

    Eight years after Spectre first showed up, the same class of CPU flaw has found another way in. Researchers have disclosed Branch Target Reuse (BTR), a Spectre v2 variant that targets just-in-time (JIT) compilers. In their Linux proof of concept, it recovered the root password hash from an Intel...

    Windows NT vs Linux Security: Why AI Agents Reopened the Kernel Debate

    Some arguments never really end. Vi versus Emacs, tabs versus spaces, and the one that has kept kernel people busy since the early 1990s: Windows NT versus Unix-like systems. It is back this week, and the person who restarted it has an unusual view from the inside. Laurie Kirk is a Google...

    Linux Kbuild v4 Patches Cut EPYC Kernel Builds to 15 Seconds

    A pending Linux build-system patch series from Arm kernel developer Lorenzo Stoakes cut a clean x86_64 defconfig kernel build from 22 seconds to 15 seconds on a dual-socket AMD EPYC 9575F server. Phoronix published that result on September 25, 2026, using version 4 of the patches, which are...

    Linux Kernel Proposal Would Add Y Taint to VFIO Bind/Unbind Hosts

    Greg Kroah-Hartman has proposed a new Linux kernel taint flag, TAINT_FORCED_BIND. It would mark a running kernel whenever someone uses the driver-core bind or unbind sysfs files to manually attach a device to a driver or detach it. He says he wants this because fuzzers such as syzbot have been...

    Qualcomm Adreno 850 Linux Patches Begin Offscreen GPU Bring-Up

    Qualcomm engineers posted initial Linux kernel patches on September 23, 2026 to bring up the Adreno 850 GPU, plus a closely related Adreno 845, in the upstream MSM graphics driver. That was one day after Qualcomm announced the Snapdragon 8 Elite Extreme Gen 6. The patches start Linux enablement...

    Linux 7.3 Set to Add G502 X USB Support, Fix ELECOM Sixth Button

    Linux 7.3 is set to gain direct-USB handling for the Logitech G502 X Lightspeed mouse and a button-reporting fix for a newer ELECOM M-XT4DRBK trackball, according to Phoronix’s September 22 report, giving affected Linux users two narrowly targeted improvements rather than blanket new device...

    Linux Plans AMD SEV Status File, Changes SNP Detection

    Linux is preparing a new read-only file that lets AMD Secure Encrypted Virtualization guests report their enabled security features without exposing the processor’s broader register-access interface, giving administrators and monitoring tools a simpler way to inspect guest state once a kernel...

    Linux 7.3 Adds XPad Support for Victrix Pro BFG and Azeron

    Linux 7.3-rc4 is queued to make the wired PDP Victrix Pro BFG controller usable through the kernel’s existing XPad driver and to recognize six Azeron controller families without the manual USB-ID workarounds Linux gamers have used until now. The change is small in code terms, but it addresses a...

    Android Binder Proposal Makes Rust Required for Linux Builds

    Google’s proposed removal of the legacy C implementation of Android Binder would turn Rust from an optional alternative into the only upstream Binder driver for future Linux kernels. For Windows developers who build Android platform images under WSL, maintain Android Common Kernel trees, or...

    Linux Scheduler Patch Would Spread Bursty Tasks Across Idle CPUs

    A proposed Linux scheduler change from Arm engineer Christian Loehle would randomize how the kernel chooses between equally suitable idle CPUs, addressing a race in which several tasks can independently converge on the same core before any of them has been placed there. For owners of...

    Linux Kernel AI Aids Debugging, but Humans Still Validate Fixes

    The Linux kernel’s recent AI experiments show a more useful division of labor than the usual “AI writes code” pitch: models can accelerate the investigation, but maintainers still have to establish that a reported defect is real and that a fix is safe. The catch is that the submitted story...

    Ubuntu 26.10 Benchmarks: Wildcat Lake Gains and Limits

    A development build of Ubuntu 26.10 delivered a reported overall performance advantage of about 4% over fully updated Ubuntu 26.04 LTS on one Intel Core 3 304 laptop, but the result is more useful as an early indicator than as a blanket upgrade recommendation. Phoronix reported that its...
