This is not a direct solution to the problem. but, if you do not want to display the message, you could change SELinux to permissive mode or disable it. Is not recommended because, SELinux is a Linux feature that provides the mechanism for supporting access control security policies.

How to change to permisive mode (recommended)

su

cp /etc/selinux/config /etc/selinux/config.bak

sudo gedit /etc/selinux/config

change SELINUX=enforcing for SELINUX=permisive

How to disable

su

cp /etc/selinux/config /etc/selinux/config.bak

sudo gedit /etc/selinux/config

change SELINUX=enforcing for SELINUX=disabled

There is a bug with the default kernel. Check here
