The Unbreakable Enterprise Kernel Release 4 (UEK R4) is Oracle's fourth major release of its heavily tested and optimized operating system kernel for Oracle Linux 6 Update 7 or later, and Oracle Linux 7 Update 1 or later, on the x86-64 architecture. It is based on the mainline Linux kernel version 4.1.12.
The 4.1.12-94.1.8 release is the fourth update release for UEK R4. It includes security and bug fixes, as well as driver updates. This kernel has been tested within environments running the latest available Oracle Linux releases: Oracle Linux 6 Update 8, Oracle Linux 6 Update 9 and Oracle Linux 7 Update 3.
Oracle actively monitors upstream checkins and applies critical bug and security fixes to UEK R4.
UEK R4 uses the same versioning model as the mainline Linux kernel version. It is possible that some applications might not understand the 4.1 versioning scheme. However, regular Linux applications are usually neither aware of nor affected by Linux kernel version numbers.
