Hello, tried to install the free Symlink Protection but getting error-free' patch type is unavailable for your kernel
I read somewhere in the cpanel forum that the symlink protector included with the purchased license.
My Q uestion is : how to remove the free kernel that was installed with the command - curl -s | bash

$ rpm -q kernel

This is the SSH installation log when tried to run the free symlink protection:

Symlink protection is already there in CloudLinux OS kernel, so there's no 'free' patches available for it.
You can find more information on symlink protection in CloudLinux OS here:

Anyway, you can use KernelCare to patch your kernel for all other vulnerabilities provided you have a license for it.
