CVE-2025-40360

Local crash via NULL plane-state dereference

Published Dec 16, 2025 · Updated Dec 16, 2025

NULL pointer dereference in DRM sysfb in the Linux kernel allows local users to crash the system during a shadow-plane reset. The __drm_gem_reset_shadow_plane() helper dereferences the current plane state when it is NULL instead of forwarding NULL to downstream reset helpers. Local low-privileged access and a reachable sysfb shadow-plane reset path are required; the bounded consequence is a kernel crash and service interruption.
