How to fix?

Upgrade Debian:11 openssh to version 1:7.4p1-1 or higher.

NVD Description

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

sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c.
