How to fix?

Upgrade Ubuntu:21.10 zlib to version 1:1.2.11.dfsg-2ubuntu7.1 or higher.

NVD Description

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

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.
