## Overview

A flaw was found in the `drm/amdgpu` component of the Linux kernel. 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.
