CVE-2024-44980

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Fix opregion leak

Being part o the display, ideally the setup and cleanup would be done by

display itself. However this is a bigger refactor that needs to be done

on both i915 and xe. For now, just fix the leak:

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.
