"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex\n\nmt7615_suspend() acquired the mt76 mutex and then called\ncancel_delayed_work_sync() on mac_work. mt7615_mac_work() acquires the\nsame mutex via mt7615_mutex_acquire() at the top of the worker, so if\nmac_work is already running and blocked on the mutex, the suspend path\ndeadlocks waiting for the work it holds the mutex against.\n\nFlush scan_work and mac_work before taking the mutex, matching the\nsuspend paths in mt7921 and mt7925. scan_work only takes the mt76\nspinlock, but moving it keeps the sequence consistent. This also keeps\nmac_work from running over an already suspended HIF, which the previous\nsplit (async cancel under the lock, sync cancel after release) would\nhave allowed."
