Dirty Cow on my CentOS 7 VPS?

    i'm kind of freaking out about the Dirty Cow CVE announcement (see here) and have been trying to get some info on whether the kernel of my VPS is vulnerable..
    Although it is CentOS 7.2 (controlled via WHM 58.0-32), the kernel seems to be a very ancient 2.6.32-042stab113.11
    i don't really care whether the kernel is bleeding edge or not, but i'm having a lot of trouble finding documentation on this kernel, and on whether it is vulnerable (though it must be, since the vulnerability seems to go back 11 years)..
    i've tried 'yum update', and the system update in WHM (set to the General Availability).

    If anyone could provide guidance, that would be great!

    This has already been patched on all of our VPS systems. You have nothing to worry about.

    You have nothing to worry about and no need to freak out :) .
    The way our virtualization works the kernel is controlled on the node side of things and has already been patched a couple days ago.

    For all dedicated servers you would need to update the kernel and reboot.

    Open a terminal and ssh to your server.

    From here simply enter the following command and press Enter:

    yum -y update kernel
    This will update your kernel and patch it too.

    If you are unsure or not ssh-savvy please open a ticket with Support and we can take care of this for you.
