SELinux is preventing /sbin/unix_chkpwd from 'getattr' accesses on the filesystem /sys.

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

If you believe that unix_chkpwd should be allowed getattr access on the sys 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:
# grep unix_chkpwd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
