Overview

CVE-2024-46712 is a medium-severity vulnerability. It was published on September 13, 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/vmwgfx: Disable coherent dumb buffers without 3d

Coherent surfaces make only sense if the host renders to them using

accelerated apis. Without 3d the entire content of dumb buffers stays

in the guest making all of the extra work they're doing to synchronize

between guest and host useless.

Configurations without 3d also tend to run with very low graphics

memory limits. The pinned console fb, mob cursors and graphical login

manager tend to run out of 16MB graphics memory that those guests use.

Fix it by making sure the coherent dumb buffers are only used on

configs with 3d enabled.

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.
