Description

A flaw was found in the Linux kernel's drm/sun4i backend component. This vulnerability occurs because the drm_atomic_get_plane_state() function can return an error pointer, which is not properly checked before being dereferenced. An attacker could potentially trigger this unchecked dereference, leading to a system crash or instability (Denial of Service).
