Detailsinfo

A vulnerability classified as very critical has been found in Linux Kernel up to 6.18.45/7.1.9. This affects the function drm_log_draw_kmsg_record of the file drivers/gpu/drm/drm_log.c of the component DRM Log. The manipulation of the argument len with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/log: Fix out-of-bounds read on empty message length drm_log_draw_kmsg_record() accesses s[len - 1] to strip the trailing newline, but len is unsigned int. If len is 0, the subtraction wraps to UINT_MAX, causing an out-of-bounds read. Add an early return when len is 0.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-80741 since 08/26/2026. The exploitability is told to be easy.
