I find it unlikely that you can connect with that to any WPA2 APs. Some
other parsing errors could potentially be ignored, but not including an
RSN IE would not be acceptable for WPA2 association. That is the
mechanism for negotiating use of the security parameters.

That station is seriously broken as far as WPA2 is concerned. You cannot
cause something like this with configuration. You may be able to trigger
that bug with some configurations, but it is just not possible to use
that station with WPA2 if it sends association request frames like shown
in the sniffer trace.

Have you tried using that station with that other AP using the same WPA2
