"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wcn36xx: Fix potential use-after-free in TX ack timer teardown\n\nwcn36xx_dxe_deinit() tears down the TX ack timer with timer_delete(),\nwhich only dequeues the timer and does not wait for a callback that is\nalready executing; the preceding free_irq() calls synchronize the\ninterrupt handlers only. The callback, wcn36xx_dxe_tx_timer(), can\ntherefore be running past the teardown and use the wcn freed along\nwith the ieee80211_hw in wcn36xx_remove(): it takes wcn->dxe_lock,\nreads wcn->tx_ack_skb and passes wcn->hw to\nieee80211_tx_status_irqsafe().\n\nFix this by using timer_shutdown_sync(), which waits for a running\ncallback and also prevents the timer from being rearmed again. The\ntimer is set up again by wcn36xx_dxe_init() on the next start, so the\nstart/stop cycle is unaffected.\n\nThis issue was found by an in-house static analysis tool."
