Unauthenticated IKE packet processing DoS
Published Jan 11, 2022 · Updated Jan 2, 2025
Windows Internet Key Exchange (IKE) Extension denial of service in affected Microsoft Windows builds allows remote attackers to interrupt service via network requests. Microsoft identifies the vulnerable locus as the IKE Extension but does not publicly describe the malformed-input operation that causes the failure. No authentication or user interaction is required, and the consequence is service availability loss without reported confidentiality or integrity impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
