Overview

CVE-2024-42091 is a medium-severity vulnerability. It was published on July 29, 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: Check pat.ops before dumping PAT settings

We may leave pat.ops unset when running on brand new platform or

when running as a VF. While the former is unlikely, the latter

is valid (future) use case and will cause NPD when someone will

try to dump PAT settings by debugfs.

It's better to check pointer to pat.ops instead of specific .dump

hook, as we have this hook always defined for every .ops variant.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
