Description
In the Linux kernel, the following vulnerability has been resolved:
NFC: digital: fix possible memory leak in digital_in_send_sdd_req()
'skb' is allocated in digital_in_send_sdd_req(), but not free when
digital_in_send_cmd() failed, which will cause memory leak. Fix it
by freeing 'skb' if digital_in_send_cmd() return failed.
