Last modified

CVE-2026-80741 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
