Is this vulnerability remotely exploitable over the air or network?

Yes. If a MAVLink link (e.g., telemetry radio, Wi-Fi/UDP, or network bridge) is reachable by an attacker and MAVLink signing is not enforced, the attacker can send unauthenticated messages that the system will process as if they were legitimate.

Does exploitation require prior authentication or physical access?

It depends on the deployment. Physical access to a serial port or RF proximity to a telemetry link may be sufficient; no logical authentication is required at the protocol level when signing is disabled. If MAVLink is bridged onto an IP network, being on the same network segment can be enough.

What is the safest general fix pattern?

The most robust pattern is to enable MAVLink 2.0 message signing on all control and telemetry endpoints and configure systems to reject unsigned traffic. This should be combined with network segmentation and, where possible, additional encryption or tunneling to protect confidentiality and integrity.
