MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/dscompress.cc, when an error occurs (pthreadcreate returns a nonzero value) while executing the method createworkerthreads, 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.
