Summary
The Linux kernel's iwlwifi wireless driver (its MLD component) is affected. A harmless-looking kernel warning could be triggered when a system suspends with Wake-on-WLAN enabled while not connected to any network; the impact is limited to a spurious warning message in the kernel log rather than a security compromise.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
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.
