Overview

CVE-2026-80936 is a high-severity vulnerability. It was published on September 11, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7925: cancel mlo_pm_work on stop

mt7925 queues mlo_pm_work with a 5 second delay during multi-link

power-save setup and never cancels it on the stop path. If the device is

torn down inside that window, the work outlives the teardown and its timer

fires afterwards, trying to queue onto the workqueue that is already gone:

workqueue: cannot queue mt7925_mlo_pm_work [mt7925_common] on wq phy0

WARNING: kernel/workqueue.c:2283 at __queue_work+0x59/0xa0, CPU#1: swapper/1/0

call_timer_fn+0x2a/0x140

__run_timers+0x203/0x330

run_timer_softirq+0x86/0xf0

mt7921 already has its own stop callback, so add one for mt7925 that

cancels the work before calling mt792x_stop(). mt7925_ops backs both the

PCIe and USB drivers, so this covers both.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
