It is stated that ath9k_htc_rx_msg() either frees the provided skb or passes its management to another callback function. However, the skb is not freed in case there is no another callback function, and Syzkaller was able to cause a memory leak. Also minor comment fix.
The comment fix seems to be missing from this version? So either it should be reinstated, or the commit message updated to not mention it... -Toke
