NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-150300_59_201-default package and not the kernel-livepatch-5_3_18-150300_59_201-default package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/plane: Move range check for format_count earlier

While the check for format_count > 64 in __drm_universal_plane_init() shouldn't be hit (it's a WARN_ON), in its current position it will then leak the plane->format_types array and fail to call drm_mode_object_unregister() leaking the modeset identifier. Move it to the start of the function to avoid allocating those resources in the first place.
