How to fix?

Upgrade Debian:11 chrony to version 1.29-1 or higher.

NVD Description

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

cmdmon.c in Chrony before 1.29 allows remote attackers to obtain potentially sensitive information from stack memory via vectors related to (1) an invalid subnet in a RPY_SUBNETS_ACCESSED command to the handle_subnets_accessed function or (2) a RPY_CLIENT_ACCESSES command to the handle_client_accesses function when client logging is disabled, which causes uninitialized data to be included in a reply.
