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

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

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