How to fix?

Upgrade Ubuntu:21.10 cloud-init to version 21.3-1-g6803368d-0ubuntu3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cloud-init package and not the cloud-init package as distributed by Ubuntu. See How to fix? for Ubuntu:21.10 relevant fixed versions and status.

In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords.
