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.
