- Summary
- wifi: mt76: mt7603: initialize global station WCID
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7603: initialize global station WCID
mt7603 uses a driver-private global station WCID for frames that have neither a station nor a vif, including frames injected through a monitor interface. Unlike the core global WCID initialized by mt76_register_device(), this WCID is published without ever being passed to mt76_wcid_init().
Since commit 0335c034e726 ("wifi: mt76: fix race condition related to checking tx queue fill status"), mt76_tx() queues every such frame on the WCID's tx_pending or tx_offchannel queue and links its tx_list. The first injected frame therefore reaches __skb_queue_tail() with an uninitialized sk_buff_head and dereferences a NULL prev pointer.
Initialize the WCID before publishing it.
The fix was tested on an MT7603 PCIe device. Three wildcard probe requests were injected through a monitor interface. The hardware queue head and tail advanced from 0 to 3 and a second radio captured the third request over the air. No oops or reset occurred. After restoring AP mode, a 150 MB transfer also completed without a reset.
