CVE-2023-34398

Head-unit crash via malformed USB profile archive

Published Feb 13, 2025 · Updated Mar 18, 2025

A null pointer dereference in Mercedes-Benz NTG6 profile import allows physically proximate attackers to crash the head unit via USB. The profile-import path passes serialized table values to Boost archive deserialization, where malformed data triggers a null pointer dereference. Physical access to the vehicle and interaction with its exposed USB import service are required, and the reported consequence is loss of availability.
