The Unbreakable Enterprise Kernel Release 5 (UEK R5) is a heavily tested and optimized operating system kernel for Oracle Linux 7.5 and later on the x86-64 and 64-bit Arm (aarch64) architectures. It is based on the mainline Linux kernel version 4.14.35. This release also updates drivers and includes bug and security fixes.

Oracle actively monitors upstream check-ins and applies critical bug and security fixes to UEK R5.

UEK R5 is initially released with the 4.14.35-1818 version and build of the kernel.

UEK R5 uses the same versioning model as the mainline Linux kernel version. It is possible that some applications might not understand the 4.14 versioning scheme. However, regular Linux applications are usually neither aware of nor affected by Linux kernel version numbers.
