Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: wifi: rtl818x: Kill URBs before clearing tx status queue In rtl8187_stop() move the call of usb_kill_anchored_urbs() before clearing b_tx_status.queue. This change prevents callbacks from using already freed skb due to anchor was not killed before freeing such skb.
