Description
Without privileged group owners, audio devices will be vulnerable to being used as eaves-dropping devices by malicious users or intruders to possibly listen to conversations containing sensitive information.
ℹ️ Check
Check the group owner of audio devices using commands:
# /usr/sbin/lsdev -C | grep -i audio
aud0 Available USB Audio Device
# ls -lL /dev/*aud0
cr--r--r-- 1 root system 16, 0 Jan 24 07:25 aud0
If the group owner of an audio device is not "root", "sys", "bin", or "system", this is a finding.
✔️ Fix
Change the group owner of the audio device using command:
# chgrp system <audio device>
