What is CVE-2022-31622?

An issue in MariaDB Server prior to version 10.7 allows local users to exploit an improper thread locking mechanism. When an error occurs during the creation of worker threads, the lock is not released correctly, resulting in a potential deadlock. This can lead to a Denial of Service, affecting the availability of the database server. The vendor describes this as an improper locking bug rather than a security vulnerability with severe consequences.
