  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7996: hold dev-\u003emt76.mutex while disabling tx worker in SER\n\nmt7996_mac_reset_work() parked the tx worker and disabled the RX/TX NAPIs\nbefore taking dev-\u003emt76.mutex. mt76_worker_disable()/_enable() are plain\nkthread park/unpark, not refcounted, and __mt76_set_channel() toggles the\nsame worker and the MT76_RESET bit under the mutex. An L1 SER racing a\nchannel switch could therefore have the worker unparked and MT76_RESET\ncleared while the reset path resets the DMA rings, corrupting descriptors\nor tokens. Take the mutex before disabling the worker, as mt7915 does.",
