About this tag
The linux kernel tag on WindowsForum.com covers security vulnerabilities and bug fixes in the Linux kernel, with a focus on driver-specific issues. Recent threads detail CVEs affecting AMDGPU, ath6kl Wi-Fi, Nouveau, and hardware-monitoring drivers for NZXT and Corsair devices, as well as Arm FF-A firmware. Each entry clarifies that these are Linux kernel problems, not Windows or firmware issues, and provides specific kernel versions containing fixes. The tag is useful for Linux administrators and enthusiasts seeking accurate, non-sensationalized information about kernel updates and their practical implications, emphasizing the need to update the kernel rather than other software components.

    CVE-2026-68401: Update Linux on Arm Kernels, Not Firmware

    CVE-2026-68401 is a Linux kernel memory-corruption fix in the Arm FF-A driver, not a BIOS, UEFI, or device-firmware update. Administrators running Linux on Arm systems that use Firmware Framework for Arm A-profile services should take the practical action: move to a vendor kernel that includes...

    CVE-2026-68245: Update Linux AMDGPU for PASID Race Fix

    CVE-2026-68245 fixes a race in the Linux kernel’s AMDGPU virtual-memory code that can dereference a virtual-machine pointer after the lock protecting its PASID lookup has been released. The immediate action for Linux systems using the in-kernel amdgpu driver is to take the vendor kernel update...

    CVE-2026-68247 Fixes Linux i915 Panel Bounds Check

    CVE-2026-68247 closes a missing bounds check in the Linux kernel’s Intel i915 graphics driver, preventing an invalid panel_type2 value in firmware-supplied display data from being accepted when the driver initializes a second internal display panel. The immediate action is straightforward: Linux...

    CVE-2026-68361: Patch Linux Corsair PSU Driver UAF

    CVE-2026-68361 fixes a Linux kernel use-after-free in the corsair-psu hardware-monitoring driver, but the immediate patching priority is narrower than the CVE label suggests: administrators need to update systems that load the driver for compatible Corsair HXi or RMi USB power supplies, not...

    CVE-2026-68410: Linux Libertas USB Leak, Not Windows

    CVE-2026-68410 is a narrowly scoped Linux kernel memory-leak fix for the Marvell Libertas Wi‑Fi driver’s USB firmware-download path, and it is not a Windows vulnerability in the ordinary desktop or enterprise sense. The flaw affects systems that both run an affected Linux kernel and use...

    CVE-2026-68151 Is Not a Windows Vulnerability or Microsoft Patch

    CVE-2026-68151 describes a Linux kernel flaw in the FDPIC ELF program loader that lets a specially constructed executable declare multiple PT_INTERP segments, causing the kernel to retain unintended interpreter-file references and write denials. The upstream fix landed in Linux 7.2-rc5 on July...
