5.5 · MEDIUM
Published Apr 2, 2024 linux CWE-459 EPSS 0.22% (13th pctl)

Overview

CVE-2024-26667 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 2, 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/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup

The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback

in case of YUV output") introduced a smatch warning about another

conditional block in dpu_encoder_helper_phys_cleanup() which had assumed

hw_pp will always be valid which may not necessarily be true.

Lets fix the other conditional block by making sure hw_pp is valid

before dereferencing it.

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.
