CVE-2026-18096

Local service interruption via undisclosed memory leak

Published Aug 12, 2026 · Updated Aug 12, 2026

Resource exhaustion in IBM Db2 Server 12.1.5 allows local users to interrupt database service through a memory leak. IBM has not disclosed the affected function, input, or resource-release operation, so the precise trigger and leak path remain unavailable. Exploitation requires low-privileged local access and no user interaction; the reported consequence is limited to reduced availability.
