package versions:

Ubuntu 25.04
  linux-image-6.14.0-1014-oracle  6.14.0-1014.14
  linux-image-6.14.0-1014-oracle-64k  6.14.0-1014.14
  linux-image-oracle              6.14.0-1014.14
  linux-image-oracle-6.14         6.14.0-1014.14
  linux-image-oracle-64k          6.14.0-1014.14
  linux-image-oracle-64k-6.14     6.14.0-1014.14

Ubuntu 24.04 LTS
  linux-image-6.14.0-1014-oracle  6.14.0-1014.14~24.04.1
  linux-image-6.14.0-1014-oracle-64k  6.14.0-1014.14~24.04.1
  linux-image-oracle              6.14.0-1014.14~24.04.1
  linux-image-oracle-6.14         6.14.0-1014.14~24.04.1
  linux-image-oracle-64k          6.14.0-1014.14~24.04.1
  linux-image-oracle-64k-6.14     6.14.0-1014.14~24.04.1

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
