"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: shut down RX BA session timer on teardown\n\nTearing down an RX BA session can leave the session timer queued on a\nfreed tid_rx. Later timer-wheel processing and the timer callback itself\nthen run against freed memory.\n\nAn RX BAR handler can dereference tid_rx under RCU before teardown\nunpublishes it and stay in its read-side critical section while teardown\ndeletes the session timer. The stale handler can then rearm the timer\nafter timer_delete_sync() returns and before the RCU callback frees\ntid_rx.\n\nUse timer_shutdown_sync() so rearm attempts become ineffective once\nteardown starts. Keep reorder_timer unchanged: teardown marks the session\nremoved under reorder_lock and its release path checks that state before\nrearming. session_timer has no equivalent guard because\nieee80211_rx_h_ctrl() rearms it before taking reorder_lock."
