MSRC_CVE-2022-31621

Vulnerability from csaf_microsoft - Published: 2022-05-02 00:00 - Updated: 2022-05-28 00:00
Summary
MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_xbstream.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. Note: The vendor argues this is just an improper locking bug and not a vulnerability with adverse effects.
