Synopsis: 4.14.35-2047.513.2.2 can now be patched using Ksplice
CVEs: CVE-2022-21499

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle kernel update, 4.14.35-2047.513.2.2.


We recommend that all users of Ksplice Uptrack running UEKR5 4.14.35
on OL7 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


* CVE-2022-21499: Privilege escalation in the kernel debug subsystem.

Insufficient protection checks in the kernel debug subsystem when using KGDB
and KDB allow reads and writes to kernel memory during kernel lockdown. A
remote attacker with access to a serial port (for example, via a hypervisor
console) could use the debugger to escalate privileges.

Orabug: 34152700
