CVE-2024-22360Network attack vector

Authenticated service interruption via crafted columnar query

Published Apr 3, 2024 · Updated Feb 27, 2025

Improper input validation in IBM Db2 11.5 allows remote authenticated users to interrupt service with a crafted columnar-table query. IBM identifies the locus only as query processing for certain columnar tables and does not disclose the rejected input, affected operation, or replication steps. A valid low-privilege database session is required, and successful exploitation interrupts database availability by an undisclosed failure mode without reported data disclosure or modification.
