A fix has been applied in the Linux kernel source (commits d4158bc784f4b45c8daa446a8e1c29eb11f63674 and 301b0dfa9db3f1e204de95e803bbd88fbd878c7c). Users should update to the fixed kernel version to avoid the WARN_ON issue during WoWLAN suspend. No additional mitigation is required.
Description
A vulnerability in the Linux kernel's iwlwifi driver related to Multi-Link Device (MLD) handling during WoWLAN suspend without netdetect configuration has been resolved. The issue involved the driver generating warnings (WARN_ON) when suspending WoWLAN without an active network connection or netdetect configured. The fix removes the warning and ensures the driver cleanly handles this scenario by disconnecting and suspending properly.
