SELinux is preventing /bin/ps from using the 'sys_ptrace' capabilities.

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

If you believe that ps should have the sys_ptrace capability 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 /bin/ps /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
