Detailsinfo

A vulnerability was found in NVIDIA GPU Driver (Hardware Driver Software) (version now known). It has been classified as critical. This affects the function DxgkDdiEscape in the library nvlddmkm.sys of the component Kernel Mode Layer. The manipulation with an unknown input leads to a missing release of file descriptor or handle after effective lifetime vulnerability. CWE is classifying the issue as CWE-775. The product does not release a file descriptor or handle after its effective lifetime has ended, i.e., after the file descriptor/handle is no longer needed. This is going to have an impact on 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 (nvlddmkm.sys) handler for DxgkDdiEscape where a handle to a kernel object may be returned to the user, leading to possible denial of service or escalation of privileges.

The bug was discovered 10/18/2016. The weakness was shared 12/16/2016 (Website). The advisory is shared at nvidia.custhelp.com. This vulnerability is uniquely identified as CVE-2016-8819 since 10/18/2016. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 27 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 95370 (NVIDIA Windows GPU Display Driver 34x.x < 342.00 / 367.x < 369.73 / 367.x < 369.71 (GRID) / 375.x < 375.63 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment.
