INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running OL 7, RHEL 7,

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


DESCRIPTION

* 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.
