Description Gianluca Gabrielli 2022-05-26 15:29:34 UTC

MariaDB Server before 10.7 is vulnerable to Denial of Service. In
extra/mariabackup/ds_compress.cc, when an error occurs (i.e., going to the err
label) while executing the method create_worker_threads, the held lock
thd->ctrl_mutex is not released correctly, which allows local users to trigger a
denial of service due to the deadlock.
