Description
A vulnerability in the Linux kernel's drm/i915 driver involves improper ordering of unlinking NV12 planes, which can cause parts of the plane state to be overwritten incorrectly. This occurs when a plane previously used as a Y plane is reconfigured as a normal plane by user space, leading to a state clobbering issue. The flaw was fixed by unlinking NV12 planes earlier in the processing sequence to prevent state corruption.
