11 Oracle Linux 8 Kernel Reference
The information provided in this reference can help you to understand the different kernel versions that are available for Oracle Linux 8.
Oracle Linux 8 Kernel Version Matrix
The following tables provide an overview of kernel availability on Oracle Linux 8 releases. You can use these tables to identify the initial UEK and RHCK kernel package versions for each release and to see which UEK releases are available for each update level. Never pin a system to an update level or a particular kernel version for an indefinite period, or the system becomes insecure as it doesn't receive the latest patches and security updates.

UEK Version Mappings
The following table provides the mapping between UEK releases and the kernel versions that they're associated with. The table is useful when trying to identify a particular UEK update level against the kernel version reported by the system. Note that to keep a system secure with the latest patches, always run the latest update level for any UEK release.
