CVE-2026-74353

Local GPU denial of service via unresumed queues

Published Aug 15, 2026 · Updated Aug 15, 2026

Denial of service in the Linux kernel allows local users to interrupt AMD GPU work through a failed queue suspension. The amdkfd queue-removal path failed to run resume_all after suspend_all returned an error, leaving otherwise healthy queues suspended, and it skipped remove_queue, so a failed removal did not schedule a GPU reset. Exploitation requires local low-privileged access and an AMD GPU using KFD; the resulting impact is interruption of GPU functionality rather than data disclosure or modification.
