CVE-2025-36136

Local service interruption via startup-state misdetection

Published Nov 7, 2025 · Updated Nov 7, 2025

Denial of service in IBM Db2 11.5.0 through 11.5.9 and 12.1.0 through 12.1.2 allows local users to interrupt the database service. The database monitor script misidentifies an instance as still starting when another process exposes the script's full path or includes the instance name and script in its command line. The issue affects Linux and UNIX servers, requires local process visibility, and has no reported confidentiality or integrity impact.
