How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream mariadb-10.3 package and not the mariadb-10.3 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when an error occurs (i.e., going to the err label) while executing the method create_worker_threads, the held lock thd->ctrl_mutex is not released correctly, which allows local users to trigger a denial of service due to the deadlock.
