The driver never validates that\nGUD_ROTATION_0 is present, so a device that omits it from its\nGUD_PROPERTY_ROTATION triggers the\nWARN_ON(rotation & ~supported_rotations) in\ndrm_plane_create_rotation_property()\n\nFix this by skipping the creation of rotation property if the device\ndoesn't have the GUD_ROTATION_0 bit\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
