Unauthenticated service interruption via null pointer dereference
Published Oct 10, 2023 · Updated Apr 14, 2025
Null pointer dereference in the AllJoyn API in Microsoft Windows allows remote attackers to interrupt the service via network traffic. Microsoft identifies the weakness as a null pointer dereference but has not disclosed the affected API operation or malformed input that triggers it. The reachable path requires no authentication or user interaction, and successful exploitation affects availability without reported data access or modification.
