Summary
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.
