How to fix?

Upgrade Debian:11 postgresql-13 to version 13.13-0+deb11u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-13 package and not the postgresql-13 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
