Users with Oracle Linux Premier Support can now use Ksplice to patch against the latest Oracle Linux Security Advisory, ELSA-2021-5226. INSTALLING THE UPDATES We recommend that all users of Ksplice on OL 8 install these updates. You can install these updates by running: # ksplice -y user upgrade 32-bit applications should be restarted after upgrading the on-disk openssl RPMs and statically linked applications using openssl should be rebuilt to include these fixes.

Refer to the installation instructions for the Enhanced Ksplice Client in the Ksplice User's Guide for more details. Systems may be prepared for Ksplice patching by installing the Ksplice aware packages in advance, prior to installing the enhanced Ksplice client.
