Update of a kernel only

[alexanderyegorov]

Hi CentOS community,

Several servers I am taking care of are at CentOS 6.2. I've found that in order to cover some vulnerabilities on them, kernel needs to be updated. However the trick is that I need to update kernel only, not the rest of the system.
Question is : would kernel-only update cause any issues with applications running on those servers? E.g. could a call through glibc to kernel fail because kernel is newer than glibc?
Does someone has experience with such update?

Why do you want to run with years of security updates not installed?

There are way more vulnerabilities to worry about than just the kernel.

The Redhat errata pages all ship with a line in them that says: "Before applying this update, make sure all previously released errata relevant to your system have been applied.". If you want to try it and see then you can do so but there are guarantees that such a new kernel will work with such an old system and even if it does a quick read of the rest of the updates from https://rhn.redhat.com/errata/rhel-server-6-errata.html should convince you that more needs to be done.
