CVE-2022-1195: Use After Free

First published: Mon Feb 21 2022(Updated: )

A use-after-free vulnerability was found in drivers/net/hamradio in the Linux kernel. In this flaw, a local attacker with a user privilege may lead to a denial of service (DOS) problem, when mkiss or sixpack device is detached, and reclaim resources early.
