CVE-2025-36015Network attack vector

Authenticated service interruption via invalid quantity input

Published Dec 8, 2025 · Updated Dec 8, 2025

Improper input validation in IBM Controller 11.1.0 through 11.1.1 allows remote authenticated users to interrupt the service. The application fails to validate a user-specified quantity size, but IBM has not disclosed the affected request, code path, or resource whose handling causes the denial of service. Reachability requires an authenticated network session; IBM does not state whether the interruption takes the form of a crash or hang.
