Technical description
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda/hdmi: Fix breakage at probing nvhdmi-mcp driver
After restructuring and splitting the HDMI codec driver code, each
HDMI codec driver contains the own build_controls and build_pcms ops.
A copy-n-paste error put the wrong entries for nvhdmi-mcp driver; both
build_controls and build_pcms are swapped. Unfortunately both
callbacks have the very same form, and the compiler didn't complain
it, either. This resulted in a NULL dereference because the PCM
instance hasn't been initialized at calling the build_controls
callback.
Fix it by passing the proper entries.

How can CyberStrike help with CVE-2025-68205?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2025-68205 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
