PUBLISHED
CVSS 5.5 MEDIUM
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.
