What is CVE-2022-31621?

A vulnerability exists in MariaDB Server versions prior to 10.7 that can lead to a Denial of Service. Specifically, when the xbstream_open method encounters an error where the destination file context is null, it fails to release an acquired lock properly. This improper handling can result in a deadlock scenario, allowing local users to exploit the situation and disrupt the database service.
