Description TEJ RATHI 2022-06-01 10:46:02 UTC 
MariaDB Server before 10.7 is vulnerable to Denial of Service. While executing the plugin/server_audit/server_audit.c method log_statement_ex, the held lock lock_bigbuffer is not released correctly, which allows local users to trigger a denial of service due to the deadlock.
