CVE-2025-68205

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel's ALSA subsystem, specifically within the HDMI codec driver code related to the nvhdmi-mcp driver. A copy-and-paste error swapped the build controls and build pcms operations for this driver. Because the callback functions have the same form, the compiler did not detect the error. This resulted in a NULL dereference when the build controls callback was invoked before the PCM instance was initialized. The issue was addressed by ensuring the correct entries are passed.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
