For anyone looking for patches for previous 6.x versions, you can take a look at https://github.com/kcgthb/RHEL6.x-COW

Previous versions are unsupported and have their own raft of security vulnerabilities that expose users to security problems. Only 6.8 should be used.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Hi,

How to check the CentOS 6.5 system is vulnerable for dirty cow or not?

# cat /etc/redhat-release
CentOS release 6.5 (Final)

# uname -r
3.14.4

If it's vulnerable then how to fix it.

And don't run a 2.5 year old non-standard non-CentOS kernel.
