Detailsinfo

A vulnerability classified as critical has been found in NVIDIA GPU Driver (Hardware Driver Software) (affected version not known). 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 input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. 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 ID 0x600000E, 0x600000F, and 0x6000010 where a value passed from a user to the driver is used without validation as the index to an internal array, leading to denial of service or potential escalation of privileges.

The bug was discovered 10/18/2016. The weakness was disclosed 12/16/2016 (Website). The advisory is shared for download at nvidia.custhelp.com. This vulnerability is traded as CVE-2016-8822 since 10/18/2016. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are known technical details, 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.

The vulnerability is also documented in the databases at Tenable (96002) and SecurityFocus (BID 95014†). The entries VDB-94571, VDB-94573, VDB-94574 and VDB-94575 are pretty similar. Once again VulDB remains the best source for vulnerability data.
