CVE-2022-49829

Local service interruption via dependency-fence leaks

Published May 1, 2025 · Updated May 11, 2026

Resource leak in the DRM scheduler in Linux kernel 4.18 through 6.0.9 allows local users to exhaust memory by terminating GPU processes. The process-exit path in drm_sched_entity_kill_jobs_cb fails to release dependency-fence references, while drm_sched_entity_kill uses the last scheduled fence without first retaining it. A local user must submit DRM scheduler jobs and kill the owning process; repeated leaks can interrupt the host, and 6.1-rc1 through 6.1-rc2 are also affected.
