Overview

CVE-2024-50144 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 7, 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/xe: fix unbalanced rpm put() with fence_fini()

Currently we can call fence_fini() twice if something goes wrong when

sending the GuC CT for the tlb request, since we signal the fence and

return an error, leading to the caller also calling fini() on the error

path in the case of stack version of the flow, which leads to an extra

rpm put() which might later cause device to enter suspend when it

shouldn't. It looks like we can just drop the fini() call since the

fence signaller side will already call this for us.

There are known mysterious splats with device going to sleep even with

an rpm ref, and this could be one candidate.

v2 (Matt B):

- Prefer warning if we detect double fini()

(cherry picked from commit cfcbc0520d5055825f0647ab922b655688605183)

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
