CVE-2024-52903Network attack vector

Authenticated server crash via crafted query

Published May 1, 2025 · Updated Sep 29, 2025

Denial of service in IBM Db2 for Linux, UNIX, and Windows 12.1.0 and 12.1.1 allows remote authenticated users to crash the server. A specially crafted query triggers the crash under specific conditions, but IBM has not disclosed the affected functionality or mishandled server operation. Successful exploitation requires low-privileged database access and high-complexity conditions, and the reported consequence is limited to a server crash.
