Description of problem:
SELinux is preventing 11-dhclient from read, open access on the archivo /usr/libexec/chrony-helper.

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

Si cree que de manera predeterminada se debería permitir a 11-dhclient el acceso read open sobre  chrony-helper file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso temporalmente ejecutando:
# ausearch -c '11-dhclient' --raw | audit2allow -M mi-11dhclient
# semodule -X 300 -i mi-11dhclient.pp
