CVE-2026-98874 · Severity: info · Published 2026-10-23

The Linux kernel's Intel WiFi driver improperly flagged a valid scenario—suspending with Wake-on-LAN enabled but no network connection and no netdetect configured—as a kernel warning. This could cause system warnings and instability in normal usage patterns where users configure WoWLAN and then suspend offline.

Technologies: [Unknown Linux kernel](https://junglewise.ai/threats/technologies/unknown-linux-kernel). Vendors: [Unknown](https://junglewise.ai/threats/vendors/unknown).

## Technical details

The vulnerability is a logic error in iwlwifi's mld/d3.c driver where a WARN_ON() was incorrectly triggered when the driver was called to suspend with WoWLAN configured but the device was not associated to a network and no netdetect was enabled. The fix removes the incorrect warning and allows normal suspend behavior by returning 1 to disconnect and suspend cleanly. This is a driver configuration handling issue, not a security bypass.
