CVE-2025-71302

Local kernel memory disclosure via Panthor fence race

Published May 8, 2026 · Updated May 8, 2026

Use-after-free in Linux kernel Panthor DRM 6.10 through 6.18.15 and 6.19 through 6.19.5 allows local users to disclose kernel memory. drm_sched_fence_get_timeline_name can dereference queue state after group_free_queue releases it because exported dma-fence references outlive teardown. Access to a Panthor render node is required to race fence inspection against group destruction or file closure; the stale pointer can also trigger a kernel oops or panic.
