Technical description

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

drm/xe: Don't overmap identity VRAM mapping

Overmapping the identity VRAM mapping is triggering hardware bugs on

certain platforms. Use 2M pages for the last unaligned (to 1G) VRAM

chunk.

v2:

- Always use 2M pages for last chunk (Fei Yang)

- break loop when 2M pages are used

- Add assert for usable_size being 2M aligned

v3:

- Fix checkpatch

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.
