Linux Kernel CVE-2026-43207

Update to patched Linux kernel versions: 7.0+ (mainline), 6.19.6+, 6.18.16+, 6.12.75+, 6.6.128+ (LTS), 6.1.165+ (LTS), 5.15.202+ (LTS), or 5.10.252+ (LTS) depending on your kernel branch. Patches available from https://git.kernel.org/stable/ with fix commits listed in NVD references. For embedded/IoT devices, consult hardware vendor for firmware updates incorporating these kernel patches, as direct kernel updates may not be feasible. If immediate patching is impossible, implement compensating controls with awareness of trade-offs: (1) Unload or blacklist the mtk_mdp kernel module if MediaTek media acceleration is not required (add 'blacklist mtk_mdp' to /etc/modprobe.d/blacklist.conf), though this disables hardware-accelerated video/image processing on affected devices, forcing CPU-based processing with performance penalties; (2) Restrict /dev/video* device access to root-only via udev rules to prevent unprivileged local users from triggering driver initialization, though this breaks legitimate applications requiring camera/video access for non-root users; (3) Deploy kernel runtime integrity monitoring (IMA/EVM) to detect kernel memory corruption attempts, adding operational overhead. For Android devices, await vendor security updates as manual kernel patching typically requires bootloader unlock and warranty void. Verify patch installation by checking kernel version (uname -r) matches patched releases and confirming fix commits via 'git log' if building from source.
