CVE-2026-72094

Kernel fault via reordered dma-fence ops access

Published Aug 15, 2026 · Updated Aug 15, 2026

NULL pointer dereference in Linux 7.1 allows attackers to trigger a kernel fault through a dma-fence race on weakly ordered platforms. The dma_fence_timeline_name() and dma_fence_driver_name() readers load fence->ops before checking the signaled bit, while reordered producer updates can permit access after the pointer becomes NULL. Reachability requires the affected dma-fence path and weak memory ordering; the public record identifies neither an attacker-controlled trigger nor a confirmed system crash.
