There is no fixed version for Debian:10 gdm3.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gdm3 package and not the gdm3 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

A flaw was found in GDM in versions prior to 3.38.2.1. A race condition in the handling of session shutdown makes it possible to bypass the lock screen for a user that has autologin enabled, accessing their session without authentication. This is similar to CVE-2017-12164, but requires more difficult conditions to exploit.
