Remote denial of service via NULL dereference
Published Jan 10, 2023 · Updated Jan 1, 2025
Denial of service in the Microsoft Windows IKE Extension allows remote attackers to interrupt IKE processing via crafted network traffic. The extension dereferences a NULL pointer while processing attacker-controlled IKE input, but Microsoft has not disclosed the affected function or packet field. No authentication or user interaction is required; the documented consequence is loss of availability, with no confidentiality or integrity impact.
