It causes\nuse-after-free bug. Moreover, if alloc_skb() fails, urb->context becomes\nNULL but rx_buf is not freed and there can be a memory leak.\n\nThe patch removes unnecessary nskb and makes skb processing more clear: it\nis supposed that ath9k_htc_rx_msg() either frees old skb or passes its\nmanaging to another callback function.\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."
