Cold rebooted several times to no effect. But updating the RUT241 firmware from 07.06.x to 07.07 fixes this problem for me - no more microcode crash if the password is wrong.
07.07 contains an updated wifi driver which probably is what fixes this problem with that router. That is of course little help to anyone experiencing the same crash with some other router :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2060193 Title: iwlwifi microcode crash when using wrong password to join a WPA3 access point Status in linux-firmware package in Ubuntu: Confirmed Bug description: I noticed that whenever I try to join a wireless network using WPA3 SAE and type the password wrong, I get a microcode crash from iwlwifi.

The driver restarts and chip seems to work OK after that, but I had one case when it started acting up afterwards. Not sure if a rogue AP could affect this somehow for DoS or otherwise.
