SELinux is preventing rngd from 'execmod' accesses on the file /usr/sbin/rngd.

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

If you believe that rngd should be allowed execmod access on the rngd file 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 rngd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
