Synopsis: 4.1.12-18.104.22.168 can now be patched using Ksplice
Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle kernel update, 4.1.12-22.214.171.124.
INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 on
OL6 and 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.
Ksplice support is available at ksplice-support_ww at oracle.com.
