Detailsinfo

A vulnerability classified as critical was found in NVIDIA GPU Driver (Hardware Driver Software) (the affected version unknown). Affected by this vulnerability is the function DxgDdiEscape in the library nvlddmkm.sys of the component Kernel Mode Layer. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

All versions of NVIDIA Windows GPU Display Driver contain a vulnerability in the kernel mode layer handler for DxgDdiEscape where the size of an input buffer is not validated leading to a denial of service or possible escalation of privileges

The bug was discovered 10/18/2016. The weakness was presented 12/16/2016 by Piotr Bania with Cisco Talos (Website). The advisory is shared at nvidia.custhelp.com. This vulnerability is known as CVE-2016-8823 since 10/18/2016. The exploitation appears to be easy. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 52 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 96002 (NVIDIA Windows GPU Display Driver 340.x < 342.01 / 375.x < 376.33 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
