Description

staging: gpib: Fix Oops after disconnect in ni_usb

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

staging: gpib: Fix Oops after disconnect in ni_usb

If the usb dongle is disconnected subsequent calls to the

driver cause a NULL dereference Oops as the bus_interface

is set to NULL on disconnect.

This problem was introduced by setting usb_dev from the bus_interface

for dev_xxx messages.

Previously bus_interface was checked for NULL only in the the functions

directly calling usb_fill_bulk_urb or usb_control_msg.

Check for valid bus_interface on all interface entry points

and return -ENODEV if it is NULL.

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
