GHSA-WRCH-9585-FW25
Vulnerability from github – Published: 2024-07-16 15:30 – Updated: 2024-07-23 15:31In the Linux kernel, the following vulnerability has been resolved:
NFC: port100: fix use-after-free in port100_send_complete
Syzbot reported UAF in port100_send_complete(). The root case is in missing usb_kill_urb() calls on error handling path of ->probe function.
port100_send_complete() accesses devm allocated memory which will be freed on probe failure. We should kill this urbs before returning an error from probe function to prevent reported use-after-free
Fail log:
