For the x86_64 platform, Oracle Linux 10 ships with the following default kernel packages:

• kernel-6.12.0-41.el10 (Red Hat Compatible Kernel (RHCK))

• kernel-uek-6.12.0-0.12.9.el10uek (Unbreakable Enterprise Kernel Release 8 (UEK R8 Developer Preview))

  For new installations, the UEK kernel is automatically enabled and installed. It also becomes the default kernel on first boot.

For the aarch64 platform, Oracle Linux ships with the UEK kernel only.

The Oracle Linux release is tested as a bundle, as shipped on the installation media image. When installed from the installation media image, the kernel's version included in the image is the minimum version that's supported. Downgrading kernel packages isn't supported, unless recommended by Oracle Support.
