Описание
The iowarrior_probe function in drivers/usb/misc/iowarrior.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.

From kernel-sec triaging: the above commits only handles the case where there
are zero endpoints, but not the case where there are some endpoints but none of the expected type.
