CVE-2022-49510

Graphics interruption via NULL right-overlay dereference

Published Feb 26, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel 5.17 before 5.17.14 and 5.18 before 5.18.3 allows local users to interrupt OMAP graphics. The omap_overlay_assign function dereferences r_ovl after omap_plane_find_free_overlay returns NULL, instead of clearing the previously assigned ovl map entry. Reachability requires low-privileged local access to an OMAP DRM device and a plane assignment with no compatible right overlay; the fault interrupts the DRM operation and panics hosts configured to panic on an oops.
