Description of problem:
SELinux is preventing rngd from 'execmod' accesses on the file /usr/sbin/rngd.

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

If você acredita que o rngd deva ser permitido acesso de execmod em rngd file  por default.
Then você deve informar que este é um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
allow this access for now by executing:
# ausearch -c 'rngd' --raw | audit2allow -M my-rngd
# semodule -X 300 -i my-rngd.pp

I would just turn on the allow_execmod boolean.  Lots of badly build libraries on your system.
