Linux Kernel CVE-2026-43202

Apply kernel security updates to versions 5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, or 6.19.6 or later, depending on your kernel branch. For systems on older kernel versions, backport the fix from the upstream kernel repository (commit references: 9a9bc60ed372aaae9784ff8ad8e5f496ff15fd31, 9c3873cccb3fab54cde0605ae7093d332c99073e, or equivalent per your kernel version) by applying dma_free_coherent() in the vt8500lcdfb probe error handling path. If immediate kernel update is not feasible, mitigate by restricting local system access to trusted users only (adjust sudo/capabilities rules to prevent unprivileged access to device initialization) and monitor for repeated framebuffer probe failures in kernel logs (dmesg output) which may indicate exploitation attempts. Note that this driver is typically only loaded on systems with actual VIA VT8500 hardware; systems without this hardware are unaffected even if running vulnerable kernel versions, as the vulnerable code path is not executed.
