Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 6.15.2. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. The impact remains unknown. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2025-38130 since 04/16/2025. Neither technical details nor an exploit are publicly available.
