Descriptions
In the Linux kernel, the following vulnerability has been resolved:
NFC: digital: fix possible memory leak in digital_tg_listen_mdaa()
'params' is allocated in digital_tg_listen_mdaa(), but not free when
digital_send_cmd() failed, which will cause memory leak. Fix it by
freeing 'params' if digital_send_cmd() return failed.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: NFC: digital: corrige una posible pérdida de memoria en digital_tg_listen_mdaa() Los 'params' se asignan en digital_tg_listen_mdaa(), pero no están libres cuando falla digital_send_cmd(), lo que provocará una pérdida de memoria. Solucionelo liberando 'params' si falla la devolución de digital_send_cmd().
