5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Details

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 CAP_SYS_NICE capability to set higher priorities than PANTHOR_GROUP_PRIORITY_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, panthor_group_create now only check for priority level validity.
