Is this vulnerability remotely exploitable?

Yes. Any remote attacker capable of observing or interacting with protocols using affected handshake patterns may benefit from the weakened cryptographic properties, particularly over long-lived or high-volume connections.

What level of access does an attacker need?

The attacker typically needs network-level access to observe or participate in the handshake and subsequent traffic. They do not need access to the server or client internals, but the impact is most significant when they can correlate or analyze many sessions using the same PSK and pattern.

What is the safest general fix pattern?

Stop using invalid or `*_psk0` post-quantum patterns and move to handshake patterns that are explicitly compliant with the Noise PSK rules. Ensure the cryptographic library enforces protocol-valid pattern construction and, where possible, add runtime or configuration checks to reject unsafe patterns.
