Vulnerability from github – Published: 2024-05-22 09:31 – Updated: 2025-01-07 21:30In 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.
