Overview

CVE-2024-26938 is a medium-severity vulnerability. It was published on May 1, 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/i915/bios: Tolerate devdata==NULL in intel_bios_encoder_supports_dp_dual_mode()

If we have no VBT, or the VBT didn't declare the encoder

in question, we won't have the 'devdata' for the encoder.

Instead of oopsing just bail early.

We won't be able to tell whether the port is DP++ or not,

but so be it.

(cherry picked from commit 26410896206342c8a80d2b027923e9ee7d33b733)

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.
