CVE-2026-76679Network attack vector

Unauthenticated adjacent system crash requiring manual recovery

Published Sep 15, 2026 · Updated Sep 21, 2026

Denial of service in HPE Networking EdgeConnect SD-WAN Gateways allows remote attackers to crash the system from an adjacent network. HPE has not published the affected component, the input that reaches it, or the operation that mishandles that input. No authentication or user interaction is required, but adjacent network access is required; exploitation leaves the gateway unable to reboot without manual intervention and disrupts network operations.
