CVE-2025-38630

Kernel crash via unchecked videomode allocation failure

Published Aug 22, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux imxfb driver allows local users to crash the kernel during framebuffer registration. The imxfb registration path ignores an -ENOMEM return from fb_add_videomode(), leaves the modelist empty, and later dereferences the missing entry. Reachability requires local low-privileged access, the imxfb driver, and an allocation failure; the documented impact is availability loss only.
