CVE-2024-46837 (GCVE-0-2024-46837)
Vulnerability from cvelistv5 – Published: 2024-09-27 12:39 – Updated: 2025-05-04 09:35
VLAI?
Summary
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.
