Is this vulnerability remotely exploitable over the network?

Yes. An attacker who can establish a P2P connection to the node and send crafted protocol messages may be able to trigger a crash or shutdown without local access.

Does an attacker need authentication or privileged access to exploit this?

Typically no. The attack targets publicly exposed P2P interfaces that are designed to accept connections from unknown peers, so standard network reachability is usually sufficient.

What is the safest general fix pattern for developers?

The safest pattern is to treat all peer messages as untrusted: comprehensively validate message sizes, structure, and ranges; handle decoding errors explicitly; and ensure that any invalid or unexpected inputs cause the peer to be dropped or the message ignored rather than causing a panic or termination.
