apt-get update

to perform the kernel-level patches to Ubuntu 14.04LTS https://usn.ubuntu.com/usn/usn-3524-1/

However, I don't know how to check if the patches are successfully applied or not.

Is there a way to check and certify the patches?

I guess KPTI is unclear to newbies. – Yo Hsiao Jan 10 '18 at 21:27
I think that KPTI only addresses Meltdown. – Chai T. Rex Jan 10 '18 at 21:30
Now I tried all commands mentioned in the KPTI post. All claims the patch is not there. But how do I know if Ubuntu's official patch is installed or not? I will be assuming if it is installed then my system is fine for now. Just how to check is my question. – Yo Hsiao Jan 10 '18 at 21:35
are you using an intell processor? meltdown does not apply to non intell chips. – ravery Jan 11 '18 at 00:00
Yes, Intel® Xeon® processor E5-2620 – Yo Hsiao Jan 11 '18 at 03:24
sudo less /boot/config-$(uname -r) | grep CONFIG_PAGE_TABLE_ISOLATION – drKreso Jan 12 '18 at 10:33
