Summary
MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc when an error occurs (pthread_create returns a nonzero value) while executing the method create_worker_threads 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.
