  "title": "WireGuard: Concurrent Execution using Shared Resource with Improper Synchronization (\u0027Race Condition\u0027)",
  "description": "WireGuard, such as WireGuard 0.5.3 on Windows, does not fully account for the possibility that an adversary might be able to set a victim\u0027s system time to a future value, e.g., because unauthenticated NTP is used. This can lead to an outcome in which one static private key becomes permanently useless.",
