Description
A flaw was found in the Linux kernel's Direct Rendering Manager (DRM) Xe output/audio (OA) module. When a specific configuration emission function fails, it does not properly release allocated memory for synchronization entries. This oversight leads to a memory leak, where system memory becomes unreachable. Repeated exploitation of this flaw by a local attacker could exhaust system resources, potentially resulting in a Denial of Service (DoS).
