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… (CVE-2026-98874)
Description
A vulnerability in the Linux kernel's iwlwifi driver related to WoWLAN suspend behavior without netdetect configuration has been resolved. The issue involved the driver issuing a WARN_ON() warning when suspending WoWLAN without an active network connection or netdetect configured. The fix removes this warning and ensures the driver cleanly handles suspension in this scenario.

Technical Analysis
The Linux kernel's iwlwifi driver had a vulnerability where it would trigger a WARN_ON() warning during WoWLAN suspend if no network was connected and netdetect was not configured. This was due to mac80211 calling the driver to suspend whenever WoWLAN was configured without distinguishing connection state. The fix removes the WARN_ON() and returns 1 to disconnect before suspending, allowing clean handling of WoWLAN suspend without netdetect.
Potential Impact
The vulnerability caused unnecessary warnings during WoWLAN suspend operations when no network connection or netdetect configuration was present. There is no indication of security compromise or exploitation impact from this behavior.
Mitigation Recommendations
A fix has been applied in the Linux kernel to remove the WARN_ON() and properly handle WoWLAN suspend without netdetect. Users should update to the fixed kernel version once available. No additional mitigation is required.
