In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Restrict high priorities on group_create
We were allowing any users to create a high priority group without any permission checks. As a result, this was allowing possible denial of service.
We now only allow the DRM master or users with the CAPSYSNICE capability to set higher priorities than PANTHORGROUPPRIORITY_MEDIUM.
As the sole user of that uAPI lives in Mesa and hardcode a value of MEDIUM [1], this should be safe to do.
Additionally, as those checks are performed at the ioctl level, panthorgroupcreate now only check for priority level validity.
