Sometimes when you run cPanel Security Advisor and you get kernel out of date warning message,The warning message may be something like below:
[wpfmb type=’warning’ theme=2]Current kernel version is out of date. current: 2.6.32-358.2.1.el6, expected: 2.6.32-358.23.2.el6 Update current system software in the “Update System Software” area, and then reboot the system in the “Graceful Server Reboot” area.[/wpfmb]
In that case you need to update your server kernel.
Login to your server as root via SSH and run following command:
yum update
When asked accept kernel upgrade and Reboot server after update.
Done!!
