Maintained Kernels

Only specific kernel versions are actively maintained by Ksplice.

Note:

Ksplice on Oracle Cloud Infrastructure supports specific Linux distributions. For more information, see Oracle Ksplice on Oracle Cloud Infrastructure.

Kernels Actively Maintained With Ksplice

With Oracle Linux Premier Support or Premier Limited subscriptions, you can use Ksplice to bring various Linux kernels up-to-date with the latest important security and bug fix patches. The following table shows the distributions and kernel versions that are automatically maintained with Ksplice.

Note:

If the system is running RHEL and you recently migrated to Oracle Linux Premier Support, you must switch to RHCK to use Ksplice kernel patches. Oracle no longer maintains Ksplice patches for RHEL kernels.

Important:

If you have booted the most recent available kernel and no Ksplice updates are available for that kernel, some Ksplice commands might fail or might return an error message notifying you that the kernel version isn't yet supported by Ksplice Uptrack. These commands only succeed when Ksplice updates are available for the kernel that's running on the system. As soon as an update becomes available, the command succeeds, and the update is applied.

Kernels No Longer Actively Maintained With Ksplice

The following kernels don't receive Ksplice updates, but any Ksplice updates previously issued are still available if you have a support contract.

To maintain any of the following kernels on a listed Linux distribution, you need to manually upgrade them by using the yum update or dnf update command, or in the case of Ubuntu, by using the apt command. Kernel updates that don't use Ksplice require system reboots to be effective.
