Unlike the core global WCID initialized by\nmt76_register_device(), this WCID is published without ever being passed\nto mt76_wcid_init().\n\nSince commit 0335c034e726 (\"wifi: mt76: fix race condition related to\nchecking tx queue fill status\"), mt76_tx() queues every such frame on the\nWCID's tx_pending or tx_offchannel queue and links its tx_list. The first\ninjected frame therefore reaches __skb_queue_tail() with an uninitialized\nsk_buff_head and dereferences a NULL prev pointer.\n\nInitialize the WCID before publishing it.\n\nThe fix was tested on an MT7603 PCIe device. Three wildcard probe requests\nwere injected through a monitor interface. The hardware queue head and tail\nadvanced from 0 to 3 and a second radio captured the third request over the\nair. No oops or reset occurred. After restoring AP mode, a 150 MB transfer\nalso completed without a reset."
