Vulnerability from github – Published: 2026-10-23 12:31 – Updated: 2026-10-23 12:31

Details

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
