CVE-2022-35769Network attack vector

Unauthenticated service interruption via PPP resource exhaustion

Published Aug 9, 2022 · Updated May 29, 2025

Denial of service in Microsoft Windows PPP allows remote attackers to interrupt service by sending traffic to an exposed PPP endpoint. Microsoft has not disclosed the specific PPP parser or operation that consumes resources incorrectly; CISA maps the flaw to uncontrolled resource consumption. Reachability requires a PPP-capable remote-access endpoint, and successful exploitation affects availability without reported data exposure or modification.
