CVE-2025-38130 drm/connector: only call HDMI audio helper plugged cb if non-null

What is CVE-2025-38130?

CVE-2025-38130 is a medium-severity vulnerability in Linux kernel, published on 3 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.

Weakness: CWE-476
