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.
CentOS 6 will die in November 2020 - migrate sooner rather than later!

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.
