Description
An out-of-bounds memory access flaw was found in the USBVision USB camera driver (usbvision_probe() function in drivers/media/usb/usbvision/usbvision-video.c). The driver assumes that the interfaces numbers of the USB device are always in 0,1,2,3... order. By using a specially crafted USB device which advertises an out-of-order number on one of its interfaces, an unprivileged user with physical access to the system can trigger a kernel NULL-pointer dereference causing a system freeze (denial of service).
