Résumé:

SELinux is preventing rndc (ndc_t) "write" /dev/null (device_t).

Description détaillée:

SELinux denied access requested by the rndc command. It looks like this is
either a leaked descriptor or rndc output was redirected to a file it is not
allowed to access. Leaks usually can be ignored since SELinux is just closing
the leak and reporting the error. The application does not use the descriptor,
so it will run properly. If this is a redirection, you will not get output in
the /dev/null. You should generate a bugzilla on selinux-policy, and it will get
routed to the appropriate package. You can safely ignore this avc.

You can generate a local policy module to allow this access - see FAQ
