An L1 SER racing a channel switch could therefore have the worker unparked and MT76_RESET cleared while the reset path resets the DMA rings, corrupting descriptors or tokens. Take the mutex before disabling the worker, as mt7915 does.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>wifi: mt76: mt7996: hold dev-&gt;mt76.mutex while disabling tx worker in SER</p> <p>mt7996_mac_reset_work() parked the tx worker and disabled the RX/TX NAPIs before taking dev-&gt;mt76.mutex. mt76_worker_disable()/_enable() are plain kthread park/unpark, not refcounted, and __mt76_set_channel() toggles the same worker and the MT76_RESET bit under the mutex.
