Steps to Reproduce:
1. Login
or
2. systemctl restart NetworkManager.service
  
Actual results:
SELinux is preventing NetworkManager from read access on the file /etc/sysctl.conf.

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

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