Unspecified impact via dma-fence null dereference
Published Aug 15, 2026 · Updated Aug 15, 2026
Null pointer dereference in the dma-fence subsystem in Linux 7.1 allows attackers to cause unspecified impact via unspecified vectors. The trace_dma_fence_signaled, trace_dma_fence_wait_end, and trace_dma_fence_destroy paths read fence->ops after signaling clears the pointer. Linux has not published how attackers reach these tracepoints or whether the dereference produces an externally observable crash.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
