Description
A flaw was found in the Linux kernel's drm/amdgpu component. A local attacker could trigger a hung job, causing the amdgpu_devcoredump_format() function to recursively acquire a lock. This recursive locking can lead to a self-deadlock, resulting in a Denial of Service (DoS) where the system becomes unresponsive.
