In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex<\/p>\n
mt7615_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.<\/p>\n
Flush 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
