Overview

CVE-2024-46710 is a high-severity vulnerability. It was published on September 13, 2024 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/vmwgfx: Prevent unmapping active read buffers

The kms paths keep a persistent map active to read and compare the cursor

buffer. These maps can race with each other in simple scenario where:

a) buffer "a" mapped for update

b) buffer "a" mapped for compare

c) do the compare

d) unmap "a" for compare

e) update the cursor

f) unmap "a" for update

At step "e" the buffer has been unmapped and the read contents is bogus.

Prevent unmapping of active read buffers by simply keeping a count of

how many paths have currently active maps and unmap only when the count

reaches 0.

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.
