CVE-2024-20982Network attack vector

High-privilege server crash via optimizer processing

Published Feb 17, 2024 · Updated Nov 4, 2025

Denial of service in Oracle MySQL Server 8.0.35 and earlier and 8.2.0 and earlier allows remote authenticated users to crash or hang the server. The Server: Optimizer component processes an unspecified operation received through the MySQL protocol in a way Oracle has not publicly described. Exploitation requires high privileges and network access, and the bounded impact is a server hang or frequently repeatable crash.
