CVE-2026-90365— wifi: mt76: cancel reset and rc work on device unregister

Quick assessment

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： wifi: mt76: 在设备注销时取消重置和 rc 工作 两个驱动程序在设备注销（unregister）时都取消了 dump_work，但 reset_work 和 rc_work 却未被取消，而是仅依赖 mt76_free_device() 中的 destroy_workqueue() 来刷新。然而，mt76_free_device() 是在硬件注销且硬件停止之后才执行的。如果 reset_work 在此窗口期内触发，它会调用 ieee80211_restart_h

Vulnerability Title
wifi: mt76: cancel reset and rc work on device unregister
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: cancel reset and rc work on device unregister Both drivers cancelled dump_work on unregister but left reset_work and rc_work to be flushed only by destroy_workqueue() in mt76_free_device(), which runs after the hw is unregistered and the hardware stopped. A reset_work that fires in that window calls ieee80211_restart_hw() and re-arms mac_work on an unregistered hw, and rc_work touches station state being torn down. Cancel both up front, alongside dump_work.
