Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
staging: gpib: Fix Oops after disconnect in ni_usb<br />
<br />
If the usb dongle is disconnected subsequent calls to the<br />
driver cause a NULL dereference Oops as the bus_interface<br />
is set to NULL on disconnect.<br />
<br />
This problem was introduced by setting usb_dev from the bus_interface<br />
for dev_xxx messages.<br />
<br />
Previously bus_interface was checked for NULL only in the the functions<br />
directly calling usb_fill_bulk_urb or usb_control_msg.<br />
<br />
Check for valid bus_interface on all interface entry points<br />
and return -ENODEV if it is NULL.
