CVE-2022-27385Public exploitNetwork attack vector

Database crash via uninitialized reference array

Published Apr 12, 2022 · Updated Aug 3, 2024

Denial of service in MariaDB Server 10.7 and earlier allows remote authenticated users to crash the database with crafted SQL statements. During an UPDATE with a nested subquery, mysql_select enables select-list resolution for an empty field list, causing Item_ref processing to access an uninitialized ref_pointer_array. The attacker must be able to submit SQL statements; successful exploitation terminates the database server without a reported confidentiality impact.
