How to fix?

There is no fixed version for RHEL:7 mariadb-embedded-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mariadb-embedded-devel package and not the mariadb-embedded-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
