Details

In the Linux kernel, the following vulnerability has been resolved:

NFC: port100: fix use-after-free in port100sendcomplete

Syzbot reported UAF in port100sendcomplete(). The root case is in missing usbkillurb() calls on error handling path of ->probe function.

port100sendcomplete() 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:
