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. https://jira.mariadb.org/browse/MDEV-26574 https://github.com/MariaDB/server/commit/b1351c15946349f9daa7e5297fb2ac6f3139e4a8
This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2022-31621
