kernel: wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit

A flaw was found in the Linux kernel's ath9khtc Wi-Fi driver. An issue exists where the skbtrim function, used for resetting the length of a socket buffer skb before resubmitting a USB Request Block urb, can encounter an uninitialized length value in certain error conditions. A local attacker cou...
