CVE-2025-46583Network attack vector

Unauthenticated service interruption via malformed SMS parameters

Published Oct 27, 2025 · Updated Oct 27, 2025

Denial of service in ZTE MC889A Pro allows remote attackers to interrupt service through crafted Short Message Service interface parameters. The interface insufficiently validates input parameters before processing them, permitting malformed values to trigger the denial-of-service condition. Network access without authentication or user interaction is sufficient; ZTE has not disclosed whether the interruption is a hang, crash, or reboot.
