While processing skbs in ath9k_hif_usb_rx_stream(), the already allocated skbs in skb_pool are not freed if ath9k_hif_usb_rx_stream() fails. If we have an incorrect pkt_len or pkt_tag, the input skb is considered invalid and dropped. All the associated packets already in skb_pool should be dropped and freed. Added a comment describing this issue.</p> <p>The patch also makes remain_skb NULL after being processed so that it cannot be referenced after potential free. The initialization of hif_dev fields which are associated with remain_skb (rx_remain_len, rx_transfer_len and rx_pad_len) is moved after a new remain_skb is allocated.</p> <p>Found by Linux Verification Center (linuxtesting.org) with Syzkaller.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>wifi: ath9k: hif_usb: clean up skbs if ath9k_hif_usb_rx_stream() fails</p> <p>Syzkaller detected a memory leak of skbs in ath9k_hif_usb_rx_stream().
