Description grumpey0 2021-03-09 00:01:38 UTC 
SELinux is preventing usbmuxd from getattr access on the filesystem /sys/fscgroup.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that usbmuxd should be allowed getattr access on the cgroup filesystem by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'usbmuxd' --raw | audit2allow -M my-usbmuxd
# semodule -X 300 -i my-usbmuxd.pp
