In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix null check for pipectx->planestate in resourcebuildscaling_params
Null pointer dereference issue could occur when pipectx->planestate is null. The fix adds a check to ensure 'pipectx->planestate' is not null before accessing. This prevents a null pointer dereference.
