Overview

CVE-2024-46837 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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.
