SELinux is preventing /sbin/setfiles from 'write' accesses on the file /dev/null.

*****  Plugin catchall (50.5 confidence) suggests  ***************************

If you believe that setfiles should be allowed write access on the null 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 restorecon /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

*****  Plugin leaks (50.5 confidence) suggests  ******************************

If you want to ignore setfiles trying to write access the null file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /sbin/setfiles /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp
