Score breakdown

Buffer overflow in the auerswald_probe function in the Auerswald Linux USB driver for the Linux kernel before 2.6.27 allows physically proximate attackers to execute arbitrary code, cause a denial of service via a crafted USB device, or take full control of the system.

From the Ubuntu Security Team

It was discovered that the Auerswald usb driver incorrectly handled lengths of the USB string descriptors. A local attacker with physical access could insert a specially crafted USB device and gain root privileges.
