CVE-2023-22058Network attack vector

Authenticated server crash via undisclosed DDL flaw

Published Jul 18, 2023 · Updated Feb 13, 2025

Denial of service in MySQL Server's DDL component in Oracle MySQL 8.0.33 and earlier allows remote authenticated users to hang or crash the server. Oracle has not published the affected DDL statement, code path, or faulty operation that processes the request. Exploitation requires high privileges and network access over a supported protocol, and the bounded impact is a hang or repeatable server crash.
