Improper Locking and Resource Shutdown or Release Vulnerabilities for MariaDB

description-logoDescription

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_xbstream.cc and extra/mariabackup/ds_compress.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. And 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.
