Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: NFC: digital: corrige una posible pérdida de memoria en digital_in_send_sdd_req() 'skb' está asignado en digital_in_send_sdd_req(), pero no está libre cuando falla digital_in_send_cmd(), lo que provocará una pérdida de memoria. Solucionarlo liberando 'skb' si falla la devolución de digital_in_send_cmd().
