CVE-2021-46873
MEDIUMWireGuard - Denial of Service via Future System Time Manipulation
Title source: llmDescription
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's 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.
