CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as critical, was found in NVIDIA GPU Driver (Hardware Driver Software) (the affected version unknown). Affected is the function DxgDdiEscape in the library nvlddmkm.sys of the component Kernel Mode Layer. The manipulation with an unknown input leads to a array index vulnerability. CWE is classifying the issue as CWE-129. The product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

All versions of NVIDIA Windows GPU Display Driver contain a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape where a value passed from a user to the driver is used without validation as the index to an array, leading to denial of service or potential escalation of privileges.

The bug was discovered 10/18/2016. The weakness was released 12/16/2016 (Website). The advisory is available at nvidia.custhelp.com. This vulnerability is traded as CVE-2016-8816 since 10/18/2016. The exploitability is told to be easy. Local access is required to approach this attack. The exploitation doesn't require any form of authentication.
