How does TuxCare’s KernelCare deploy vulnerability patches
without reboots or downtime?
Our team is always on the lookout. As soon as a new vulnerability affecting a
Linux kernel is announced, we immediately get to work on a patch.
We create code that patches insecure kernel code with a secure but functionally equivalent replacement.
We compile every patch that impacts the affected kernel and deploy it to our distribution servers.
A KernelCare process running on your server checks our distribution servers every 4 hours. If a new patch is available, it can then be downloaded and applied to your running kernel – a process that can be automated.
To apply the patch in milliseconds, a special KernelCare kernel module is used.
