Oracle today released their Unbreakable Enterprise Kernel Release 5 Update 5 intended for use on their RHEL-based Oracle Linux. Oracle's "Unbreakable Enterprise Kernel" tends to be a newer Linux LTS kernel with extra features compared to what is found in the current RHEL / Red Hat Compatible Kernel builds.

Oracle Unbreakable Enterprise Kernel Release 5 is a super-set of features for what is offered by the Red Hat Compatible Kernel "RHCK". With UEK Release 5 Update 5 there are several features back-ported.

The UEK R5 Update 5 kernel has various page clearing optimizations, various file-system fixes and optimizations, RDMA improvements, and a variety of back-ported driver updates. UEK R5U5 is based on the Linux 4.14.35 LTS kernel.

More details on their UEK R5 Update 5 kernel variant via the Oracle Linux blog.

For those wanting to be on a newer kernel series, Unbreakable Enterprise Kernel Release 6 is their latest series that is tracking Linux 5.4 LTS. Presumably soon we'll see the next update to UEK R6.
