  "description": "In the Linux kernel, the following vulnerability has been resolved:  media: si470x: Fix use-after-free in si470x_int_in_callback()  syzbot reported use-after-free in si470x_int_in_callback() [1].  This indicates that urb-\u003Econtext, which contains struct si470x_device object, is freed when si470x_int_in_callback() is called.  The cause of this issue is that si470x_int_in_callback() is called for freed urb.  si470x_usb_driver_probe() calls si470x_start_usb(), which then calls usb_submit_urb() and si470x_start().  If si470x_start_usb() fails, si470x_usb_driver_probe() doesn\u0027t kill urb, but it just frees struct si470x_device object, as depicted below:  si470x_usb_driver_probe()   ...   si470x_start_usb()     ...     usb_submit_urb()     retval = si470x_start()     return retval   if (retval \u003C 0)     free struct si470x_device object, but don\u0027t kill urb  This patch fixes this issue by killing urb when si470x_start_usb() fails and urb is submitted.  If si470x_start_usb() fails and urb is not submitted, i.e. submitting usb fails, it just frees struct si470x_device object.",
