A local user with the ability to submit GPU work and trigger GPU timeout or recovery could exploit a race condition during GPU recovery. This race condition, occurring between the scheduler timeout callback and the TDR work queue, leads to a use-after-free (UAF) vulnerability. Successful exploitation can result in a kernel crash, causing a Denial of Service (DoS), and may also lead to information disclosure or privilege escalation.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2025/cve-2025-68793.json)\n\n**kernel: Linux kernel: `drm/amdgpu` use-after-free vulnerability leading to denial of service** — rated Moderate by Red Hat.
