A flaw was found in the `drm/vc4` component of the Linux kernel. This vulnerability is due to a memory leak where the Buffer Object (BO) array, allocated during a hang state, is not properly freed. A local attacker could exploit this by repeatedly triggering the hang state, leading to memory exhaustion and potentially a denial of service (DoS) on the system.
