What is CVE-2022-31623?

MariaDB Server versions before 10.7 have a vulnerability that can lead to Denial of Service. The issue arises in the extra/mariabackup/ds_compress.cc file, specifically during the execution of the create_worker_threads method. If an error occurs, the lock held by thd->ctrl_mutex is not released, which can result in deadlocks triggered by local users. This could hinder server responsiveness and availability. While the vendor characterizes it as an improper locking bug, the potential for service disruption underscores the importance of applying available patches.
