Linux Kernel EUVD-2026-26581

Upgrade to patched Linux kernel versions: 6.1.168 or later for the 6.1.x series, 6.6.134 or later for 6.6.x, 6.12.81 or later for 6.12.x, 6.18.22 or later for 6.18.x, 6.19.12 or later for 6.19.x, or upgrade to mainline kernel 7.0 or later. Patches are available from the Linux kernel stable repository at https://git.kernel.org/stable. If immediate patching is not feasible and the ti-adc161s626 driver is loaded as a module, disabling or blacklisting the module (add 'blacklist ti_adc161s626' to /etc/modprobe.d/blacklist.conf) will prevent exploitation but will disable ADC functionality for systems requiring this hardware - only viable if the ADC is not operationally necessary. For systems where the driver is compiled into the kernel and the ADC hardware is not used, removing or disconnecting the physical ADC device eliminates the attack surface but may require hardware modifications. No effective runtime workaround exists for systems actively using this ADC hardware without patching. Review systems inventory to identify which hosts use TI ADC161S626 hardware and prioritize patching those systems.
