Working with more distributions than Amazon Linux?
KernelCare Enterprise Patches All Popular Enterprise Linux Distros without Reboots, Including 
The TuxCare Rebootless Live Patching Process
As soon as a new vulnerability affecting a Linux kernel is announced, the TuxCare
team immediately gets to work on a rebootless patch.
KernelCare Enterprise then deploys each patch in less than a nanosecond:
We Create the Patch
We create code that patches insecure kernel code with a secure but functionally equivalent replacement.
We Prepare the Patch for
Deployment
We compile every patch that impacts the affected kernel and deploy it to our distribution servers.
You Receive the Patch
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.
KernelCare Applies
the Patch
The KCE kernel module – in a matter of nanoseconds – loads the updated binary into the secure kernel space and redirects all functions to the updated code – and the kernel resumes.
Because this happens in nanoseconds, no processes are
interrupted and no failover condition is ever triggered
Experience TuxCare’s rebootless Amazon Linux patching technology with zero commitment.
