Hi!

A few days ago we received the following message via WHM, Security Advisor:
-------
The system kernel is at version “3.10.0-714.10.2.lve1.4.63.el7”, but is set to boot to version “3.10.0-427.36.1.lve1.4.39.el7.x86_64”.
You must take one of the following actions to ensure the system is up-to-date:
Wait a few days for KernelCare to publish a kernel patch.
Reboot the system.
-------

Although not very happy, we rebooted the server, but the message kept coming up, thus the problem was not solved. We also waited a few days (about 15) in case KernelCare solved the problem itself... but still the problem exists up until now.
Our cPanel version is v66.0.23 on Cloudlinux 7.

Please advise.

This is a cPanel bug that goes back to at least August. See this cPanel thread for details, https://forums.cpanel.net/threads/whm-v66-0-14-you-must-reboot-the-server-to-apply-kernel-updates.608403/.

Thank you for your reply.

It appears that this is indeed cPanel bug (CPANEL-15544). A resolution for this case is planned for inclusion with cPanel version 68 and will ensure the reboot warning does not appear on systems using a custom kernel.

Hello, I have WHM CLOUDLINUX 7.4 standard v68.0.21

I got this:
[[email protected] ~]# uname -r
3.10.0-714.10.2.lve1.4.74.el7.x86_64
[[email protected] ~]# sudo kcare-uname -r
3.10.0-714.10.2.lve1.4.77.el7.x86_64
[[email protected] ~]#

It has been there for a couple of weeks or maybe more, I did restart the server a couple of times but no success...

Hello,

kcare-uname -r shows effective kernel version, this is normal.

Could you please describe the issue in more details?

Hello,

# uname -r shows the current booted kernel, and # kcare-uname -r shows effective kernel patched by KernelCare.

You can find more info in our docs.

The output looks normal, no actions required.

Cloudlinux 7.4 & WHM/cPanel v68.0.28
The system kernel is at version “3.10.0-714.10.2.lve1.4.77.el7”, but is set to boot to version “3.10.0-714.10.2.lve1.5.9.el7.x86_64”.

You must take one of the following actions to ensure the system is up-to-date:

Wait a few days for KernelCare to publish a kernel patch.

There are almost 3 weeks we start to getting this messages in WHM, security advisor:


The system kernel is at version “3.10.0-714.10.2.lve1.5.12.el7”, but is set to boot to version “3.10.0-714.10.2.lve1.5.9.el7.x86_64”.

You must take one of the following actions to ensure the system is up-to-date:

Wait a few days for KernelCare to publish a kernel patch.
Reboot the system.


After reboot is the same situation.

Can Cloudlinux team colaborate with cPanel team to avoid in the near future this kind of situations? Or to try Cloudlinux to update the boot kernel when WHM upgrade?

We bought Cloudlinux & Kernelcare specialy to avoid this threats of security.

Thank you for your response

Do you have cPanel version prior to 70?
If yes - upgrade it to WHM version 70 - it must be fixed there.
If the version is 70 - please submit us a ticket so we can see why it is not working right to fix it.

Thank you:)
