Description

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.

Affected configurations

• mariadb mariadb (< 10.2.41) • mariadb mariadb (>= 10.3.0 < 10.3.32) • mariadb mariadb (>= 10.4.0 < 10.4.22) • mariadb mariadb (>= 10.5.0 < 10.5.13) • mariadb mariadb (>= 10.6.0 < 10.6.5)
