CVE-2024-35152Network attack vector

Authenticated service interruption via excessive memory allocation

Published Aug 14, 2024 · Updated Nov 4, 2025

Excessive memory allocation in IBM Db2 Server 11.5.8 through 11.5.9 allows remote authenticated users to interrupt service via a crafted query. When a specially crafted statement queries certain tables, Db2 allocates excessive memory; IBM has not disclosed the responsible functionality or replication details. Database credentials and network access to the server are required, and the documented consequence is availability loss without data disclosure or modification.
