CVE-2025-36118Network attack vector

Unauthenticated memory disclosure via IKEv1 SA negotiation

Published Nov 17, 2025 · Updated Nov 17, 2025

Information disclosure in IBM Storage Virtualize 8.4, 8.5, 8.7, and 9.1 allows remote attackers to read device memory via IKEv1 SA negotiation. During SA negotiation, the strongSwan IKEv1 implementation exposes heap memory that was not cleared before release. No authentication or user interaction is required, and the reported consequence is read-only disclosure rather than modification or interruption.
