In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: hif_usb: Fix use-after-free in ath9k_hif_usb_reg_in_cb() It is possible that skb is freed in ath9k_htc_rx_msg(), then usb_submit_urb() fails and we try to free skb again. It causes use-after-free bug. Moreover, if alloc_skb() fails, urb->context becomes NULL but rx_buf is not freed and there can be a memory leak. The patch removes unnecessary nskb and makes skb processing more clear: it is supposed that ath9k_htc_rx_msg() either frees old skb or passes its managing to another callback function. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
