CVE-2024-42261

System crash via unchecked DRM syncobj handles

Published Aug 17, 2024 · Updated May 11, 2026

Improper handle validation in Linux 6.8 through 6.10.3 and 6.11-rc1 allows local users to crash the system via a crafted v3d timestamp query. Three parsers in drivers/gpu/drm/v3d/v3d_submit.c store unchecked null results from drm_syncobj_find for user-supplied handles. Low-privilege access to v3d submission ioctls is required; exploitation affects availability only and can interrupt the host.
