Vulnerability from github – Published: 2025-07-03 09:30 – Updated: 2025-11-20 21:30

Details

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.

Severity

5.5 (Medium)
