Is this vulnerability remotely exploitable over the internet?

No. Exploitation requires the attacker to be within wireless range of the target router and clients, as it relies on crafting and sending over-the-air 802.11 management frames.

Does an attacker need to know the Wi-Fi password or be connected to the network?

Typically no. Because the deauthentication and disassociation frames are not authenticated or encrypted, an attacker usually does not need the Wi-Fi credentials or an existing association to launch the attack.

What is the safest general fix pattern for this issue?

The most robust fix pattern is to require authenticated and integrity-protected management frames (such as enabling and enforcing PMF/802.11w) and to avoid operating in security modes that cannot support management frame protection.
