Short explanation
The iwlwifi MLD driver in the Linux kernel contains an issue that could trigger a WARN_ON during WoWLAN suspend operations without netdetect configuration. The driver is updated to cleanly handle the suspend process after disconnecting.
This vulnerability can lead to unexpected warning states during WoWLAN suspend when no network is connected and netdetect is not configured on systems using the Linux kernel iwlwifi driver. Patch status in official sources remains uncertain.
What should be done?
- Follow the vendor advisories and updates

Show the technical text from the sources
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.
