Intel® Processor Graphics Advisory
A potential security vulnerability in Intel® Processor Graphics may allow information disclosure. Intel is releasing software updates to mitigate this potential vulnerability.
Description: Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.

* Platforms based on Ivy Bridge, Bay Trail and Haswell do not have full mitigations at this time for the Windows* OS. Updating the drivers for these platforms per the recommendation below will substantively reduce the potential attack surface. Intel is working on full mitigations for these platforms and will make them available once they are validated. Linux mitigation for these platforms will be provided for the mainline kernel.
Intel recommends updating Intel® Processor Graphics Driver for Windows* and the i915 Linux Driver to the latest version (see provided table).
Windows* Operating System Driver version
- 126.96.36.19909 or higher
- 15.45.x.5077 or higher
- 15.40.x.5107 or higher
- 15.36.x.5117 or higher
- 15.33.x.5100 or higher
Updates are available for download at this location: https://downloadcenter.intel.com/product/80939/Graphics-Drivers
Linux Operating System
Linux mitigation is targeted to be available on or after January 14, 2020. Kernel version information is targeted to be available January 7, 2020.
- Mainline: 5.5-rc6 or later
- Stable: 5.4.12 or later
- LTS: 4.19.96 or later
- LTS: 4.14.165 or later
- LTS: 4.9.210 or later
- LTS: 4.4.210 or later
This issue was initially found internally by Intel.
Intel would like to thank Wenjian HE (Hong Kong University of Science and Technology), Wei Zhang (Hong Kong University of Science and Technology), Sharad Sinha (Indian Institute of Technology, Goa) and Sanjeev Das (University of North Carolina) for reporting this issue.
Intel, and nearly the entire technology industry, follows a disclosure practice called Coordinated Disclosure, under which a cybersecurity vulnerability is generally publicly disclosed only after mitigations are available.
