I want to upgrade kernel in my server


I am new on digital ocean server and I want to upgrade kernel because of “dirty COW”. when i checked in Droplets page’s Kernel it’s show this message “The kernel for this Droplet is managed internally and cannot be changed from the control panel.”

Can you tell me how can i upgrade it?

My Ubuntu version is 14.04.
