Pointer dereference in subsystem in Intel(R) Graphics Driver allows unprivileged user to elevate privileges via local access

Intel ID INTEL-SA-00089
Product family Mobile, Desktop, Server, Workstation, and Embedded platforms based on Intel® Core™ and Atom™ Processors with Processor Graphics using an identified driver.
Impact of vulnerability  Elevation of Privilege
Severity rating Important
Original release Jan 31, 2018
Last revised Jan 31, 2018

Summary:

The Intel® Graphics Drivers for Windows  Code can fail to adequately validate a pointer input.  This may lead to modification of kernel memory and a potential for an escalation of privilege.  Reference CVE-2017-5727.

Description:

The Intel® Graphics Drivers for Windows  Code can fail to adequately validate a pointer input.  This may lead to modification of kernel memory and a potential for an escalation of privilege.  The CVSS V3 rating is 7.8 (High.)

CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:H

Affected products:

Mobile, Desktop, Server, Workstation, and Embedded platforms based on Intel® Core™ and Atom™ Processors using an identified driver. 
The following table lists impacted driver code branches and the first version containing the recommended mitigation.  Driver versions having the last number greater than, or equal to, the listed version are not impacted.  Driver versions with the last number less than the listed version are impacted.  Driver code branches not listed are not currently impacted.

 

Driver Code Branch

 

 

1st Mitigated version

 

 

Notes

 

 

15.47

 

 

15.49

 

 

Not Impacted

 

 

Users can migrate to these branches if their systems are compatible.

 

 

15.46

 

 

15.46.x.4811

 

22.20.x.4811

 

 

 

Intel Recommends:

 

 

15.47.x.4785

 

22.20.x.4785

 

Or

 

15.49.x.4836

 

22.20.x.4836

 

Or

 

Subsequently released compatible versions.

 

 

Not suitable for In-Field Upgrades. 

 

 

 

 

Available now

 

 

Most Users should migrate to the latest version of 15.47 or 15.49 compatible with their system.  Releases from code branches later than 15.49 are also mitigated, and can be used if compatible.

 

 

15.45 

 

 

 

 

 

15.45.x.4821

 

 

21.20.x.4821

 

 

Available now.

 

 

15.40

 

 

15.40.x.4835

 

 

20.19.x.4835

 

 

Available now.

 

Any “x” appearing in the table above indicates the specific value, or sequence of values, is not relevant in determining if the driver version is potentially impacted or mitigated.

Check with your system’s manufacturer to see if they provide an updated graphics driver.  Alternatively, you can use the Intel® Driver and Support Assistant to identify and update your driver directly from Intel.  The Driver and Support Assistant can be found at https://www.intel.com/content/www/us/en/support.html.  
Direct links to the available graphics drivers can be found at https://downloadcenter.intel.com and searching for the relevant version number above.  You can also search for graphics drivers compatible with your particular system.  Intel recommends that users with affected drivers download and upgrade to the latest supported driver version.  The driver with the highest last number is the latest.  For example, 15.40.37.4835 is a later version than 15.40.36.4703 because 4835 is a higher number than 4703.

Recommendations:

Intel highly recommends that OEM’s remove the potentially vulnerable driver versions from download sites and replace them with the latest mitigated version of that driver code branch. Additionally, potentially vulnerable driver versions on shipping systems should be upgraded to the latest mitigated driver compatible with those systems. 

Intel’s version numbering of our graphics driver is in transition.  Our code branches are shorter lived, and upgrading the driver will more frequently result in a change in code branch.  Situations like the 15.46 mitigation involving a change in code branch to 15.47, 15.49, or a later branch will become more frequent, and instances of incompatibility will become less frequent.

Intel would like to thank an Intel Security Partner for this discovery.
