CVE-2024-37603

User-Data service restart via USB type confusion

Published Feb 13, 2025 · Updated Feb 18, 2025

Type confusion in Mercedes-Benz NTG 6 head units allows physically proximate attackers to restart the User-Data service via USB. The user data import/export function interprets prepared data as an incompatible type, causing the service instance to fail. Access to the vehicle's exposed USB interface is required, and the observed consequence is a transient service interruption because the failed instance restarts automatically.
