Does anyone know if Apple release security fixes for Airport? I know it isn’t actively developed, but you’d hope they’d release critical security fixes as they still sell them.

The main attack targets 4-way handshakes, so doesn't target access points. You should worry about updating your clients, not your AP.

Fortunately most access points will be fine, but those performing client functions (eg repeaters) will need updating.
