CVE-2026-6051

Local service interruption via crafted query compilation

Published May 27, 2026 · Updated May 27, 2026

Uncontrolled resource consumption in IBM Db2 Server 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4 allows local users to interrupt service. IBM has not disclosed which query-compiler operation mishandles the crafted query or how the small statement heap produces the denial of service. A low-privileged local account capable of executing queries is required, and the reported consequence is availability loss without data disclosure or modification.
