How to fix?

Upgrade Debian:11 sqlite3 to version 3.34.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sqlite3 package and not the sqlite3 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

A flaw was found in SQLite's SELECT query functionality (src/select.c). This flaw allows an attacker who is capable of running SQL queries locally on the SQLite database to cause a denial of service or possible code execution by triggering a use-after-free. The highest threat from this vulnerability is to system availability.
