CVE-2025-22100

Kernel crash via unlocked Panthor group iteration

Published Apr 16, 2025 · Updated Aug 5, 2026

Panthor DRM use-after-free in Linux 6.13 through 6.13.10 and 6.14 through 6.14.1 allows local users to crash the system. panthor_fdinfo_gather_group_samples iterates the group-pool xarray without its lock, permitting a group to be freed while fdinfo statistics are read. Successful exploitation requires low-privileged local access to Panthor GPU fdinfo and concurrent group teardown; the published impact is limited to availability.
