There are several ways to determine if an updated kernel is
available for the system.
Security Errata — Go to the following location for information on
security errata, including kernel upgrades that fix security
issues:
Via Quarterly Updates — Refer to the following location for
details:
Via Red Hat Network — Download and install the kernel RPM
packages. Red Hat Network can download the latest kernel, upgrade the kernel
on the system, create an initial RAM disk image if needed, and
configure the boot loader to boot the new kernel. For more
information, refer to https://www.redhat.com/docs/manuals/RHNetwork/.
If Red Hat Network was used to download and install the updated kernel, follow the
instructions in Section 37.5 Verifying the Initial RAM Disk Image and Section 37.6 Verifying the Boot Loader, only do not
change the kernel to boot by default. Red Hat Network automatically changes
the default kernel to the latest version. To install the kernel
manually, continue to Section 37.4 Performing the Upgrade.
