How to fix?

Upgrade Debian:11 ntp to version 1:4.2.8p4+dfsg-3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ntp package and not the ntp package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests.
