Overview

CVE-2025-38130 is a medium-severity vulnerability. It was published on July 3, 2025 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/connector: only call HDMI audio helper plugged cb if non-null

On driver remove, sound/soc/codecs/hdmi-codec.c calls the plugged_cb

with NULL as the callback function and codec_dev, as seen in its

hdmi_remove function.

The HDMI audio helper then happily tries calling said null function

pointer, and produces an Oops as a result.

Fix this by only executing the callback if fn is non-null. This means

the .plugged_cb and .plugged_cb_dev members still get appropriately

cleared.

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.
