Synopsis: RHSA-2020:4276 can now be patched using Ksplice
CVEs: CVE-2020-12351 CVE-2020-12352

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle kernel update, RHSA-2020:4276.


We recommend that all users of Ksplice Uptrack running RHCK 7 install
these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y
