Overview

CVE-2022-49359 is a high-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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/panfrost: Job should reference MMU not file_priv

For a while now it's been allowed for a MMU context to outlive it's

corresponding panfrost_priv, however the job structure still references

panfrost_priv to get hold of the MMU context. If panfrost_priv has been

freed this is a use-after-free which I've been able to trigger resulting

in a splat.

To fix this, drop the reference to panfrost_priv in the job structure

and add a direct reference to the MMU structure which is what's actually

needed.

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.
