CVE ID: CVE-2022-31621

Description: ** DISPUTED ** MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_xbstream.cc, when an error occurs (stream_ctxt->dest_file == NULL) while executing the method xbstream_open, the held lock is not released correctly, which allows local users to trigger a denial of service due to the deadlock. Note: The vendor argues this is just an improper locking bug and not a vulnerability with adverse effects.

Test IDs: 1.3.6.1.4.1.25623.1.0.104555 1.3.6.1.4.1.25623.1.0.104554
