How to fix "Dirty COW" on CentOS 6.8(linux 2.6.32)?

[torrent4all]

Hi team,

Do you release patches for CentOS 6.x 64bit?

I run yum info kernel, the following output
Name : kernel
Arch : x86_64
Version : 2.6.32
Release : 642.6.1.el6
Size : 32 M
Repo : updates

Is it fixed?

Please see the previous messages posted to this topic, such as this one.

"yum info kernel" is not a particularly good way to determine the status of your kernel.

Thanks everyone. I had the correct kernel after yesterday's 'yum update' and a reboot ensured that i'm currently running it.

Thanks for your reply

But I can not find this kernel on epel repo, the latest kernel is Release : 642.6.1.el6

How can I update latest kernel?

torrent4all: Please run yum clean all, then yum update (and install all the updates if any), then rpm -q kernel and uname -r and post the results here. If yum update installed a new kernel, reboot and re-run uname -r.

Hi all, and welcome to my first post. On my server Cent OS 6.8 server running Parallels Plesk 12.5.30,

uname -r gives me: 2.6.32-042stab120.5

and

rpm -q kernel gives me: kernel-2.6.32-642.6.2.el6.x86_64

Is my server patched or not? I have also already ran "yum clean all" and "yum update" as root.

Regards: Elliott.

The "stab" in that output means that you're not running CentOS at all but a product called openvz. You will need to ask your hoster if that is safe or if it needs patching.

Then why does running "cat /etc/redhat-release " give me " CentOS release 6.8 (Final)"

Thanks Trevor, always thought my server was a genuine stock CentOS with plesk installed on top.

Guess I will have to turn to the Plesk forums if my host can't help me.
