kernelcare kernel patch
KernelCare, the world's finest defender of Linux kernels, puts an end to rebooting servers just to apply patches to your kernel. It ensures that you never miss security patches, and your kernels are always up-to-date.

KernelCare eliminates the need for staying up at night to deliver kernel patch updates, or coordinating downtime with your business units and various IT departments and locations.

KernelCare applies security patches automatically to a running kernel. Live installation of security patches takes nanoseconds, doesn't alter the performance of servers, doesn't require a reboot, and quickly delivers a better, more secure Linux.
