NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

In Wireshark 3.2.0 to 3.2.1, the WireGuard dissector could crash. This was addressed in epan/dissectors/packet-wireguard.c by handling the situation where a certain data structure intentionally has a NULL value.
