CVE-2022-50400

In the Linux kernel, the following vulnerability has been resolved: staging: greybus: audio_helper: remove unused and wrong debugfs usage In the greybus audio_helper code, the debugfs file for the dapm has the potential to be removed and memory will be leaked. There is also the very real potential for this code to remove ALL debugfs entries from the system, and it seems like this is what will really happen if this code ever runs. This all is very wrong as the greybus audio driver did not create this debugfs file, the sound core did and controls the lifespan of it. So remove all of the debugfs logic from the audio_helper code as there's no way it could be correct. If this really is needed, it can come back with a fixup for the incorrect usage of the debugfs_lookup() call which is what caused this to be noticed at all.

The following products are affected by CVE-2022-50400 vulnerability.
