Description

A flaw was found in the Linux kernel's drm/panthor component. Buggy GPU jobs created by a User Mode Driver (UMD) can lead to a blockage in the memory subsystem. This prevents flush operations from completing, resulting in system hangs. A local attacker could exploit this to cause a Denial of Service (DoS), requiring a system reset to recover.

Mitigation

No mitigation is specified in collected source.
