How To Update the Kernel in CentOS / Red Hat



Updating the kernel on Red Hat Linux or CentOS Linux is a very simple process. Most commonly you will use the following command in the case of a security vulnerability, or perhaps just to verify that you’re running the most up-to-date kernel:

yum -y update kernel
