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

Description The greybus audio helper code contains debugfs file handling logic that can lead to memory leaks and potentially remove all debugfs entries from the system. This occurs because the greybus audio driver did not create the debugfs file in question, and the sound core controls its lifespan. The code has been modified to remove all debugfs logic from the audio helper code.

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