How to fix?

Upgrade Debian:11 ntp to version 1:4.2.6.p5+dfsg-3.2 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 receive function in ntp_proto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets.
