Summary
The Linux kernel from 6.15 is affected in the iwlwifi mld Wi-Fi driver. A WARN_ON() check in the driver fires when the system suspends with WoWLAN configured while not connected to a network and without netdetect configured, although this is a valid configuration. The flaw is a spurious kernel warning in a case the driver should handle cleanly.

Description from the CNA
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: don't WARN on WoWLAN suspend w/o netdetect Clearly, from a user perspective, it must be valid to configure WoWLAN and then suspend while not connected to a network. Since mac80211 doesn't distinguish these cases and simply calls the driver to suspend whenever WoWLAN is configured, the driver has to cleanly handle the case where it's called for WoWLAN, it's not connected but there's also no netdetect configured. Remove the WARN_ON() and keep returning 1 to disconnect and then suspend.
