Do you want to use KernelCare for rebootless kernel updates? But what if you are running an unsupported distribution? What if your kernel is custom, self-compiled, special, or just old? KernelCare provides Custom Kernel Patching so that your company can benefit from live patching service for your kernel. The experts on our security and kernel development team can update your kernels using KernelCare technology to apply patches to the running kernel without the need to reboot servers.
I am thrilled to let you know that we have published a toolset for livepatching of user space software, called LibCare, to GitHub. It is released under the GPL2 license and allows software developers to develop and apply patches to their running software without the need to restart it.
KernelCare is often deployed on a large number of servers. Adding those servers one by one is a hassle. In that case, KernelCare key can be used to deploy and register multiple servers at once.
Registration is still straightforward:
kcarectl --register [YOUR KEY]
The key can be obtained from CLN (see image).

In light of the recent Dirty Cow exploit, said by experts to be the “Most serious” Linux privilege-escalation bug ever, we’ve decided to push forward our prior plans to offer KernelCare for free for nonprofit organizations so that they can protect themselves from critical vulnerabilities including the Dirty Cow CVE-2016-5195.
