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 chip is Intel 9462 (AX201). Ubuntu release 22.04 LTS, faithfully
kept up to date.

When I get the password right, there's no microcode crash.
The access point is a Teltonika RUT 241 running firmware 00.07.06.8.
It's an OpenWrt derivative.
I'm not 100% sure about security implications. 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.
