In this case, the SKB can only contain a valid htc_frame_hdr\nbut after being processed in ath9k_htc_rx_msg() and passed to\nath9k_wmi_ctrl_rx() endpoint RX handler, it is expected to have a WMI\ncommand header which should be located inside its data payload.\n\nImplement sanity checking inside ath9k_wmi_ctrl_rx(). Otherwise, uninit\nmemory can be referenced.\n\nTested on Qualcomm Atheros Communications AR9271 802.11n .\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."
