Description of problem:
I just booted my laptop and logged in, then the SELinux denial notification popped up.
SELinux is preventing NetworkManager from 'read' accesses on the directory /etc/NetworkManager.

*****  Plugin restorecon (94.8 confidence) suggests   ************************

If you want to fix the label. 
/etc/NetworkManager default label should be NetworkManager_etc_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /etc/NetworkManager

*****  Plugin catchall_labels (5.21 confidence) suggests   *******************

If you want to allow NetworkManager to have read access on the NetworkManager directory
Then you need to change the label on /etc/NetworkManager
Do
# semanage fcontext -a -t FILE_TYPE '/etc/NetworkManager'

Then execute: 
restorecon -v '/etc/NetworkManager'


*****  Plugin catchall (1.44 confidence) suggests   **************************

If you believe that NetworkManager should be allowed read access on the NetworkManager directory 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
