Vulnerability Details

CVE-2016-8821

NVIDIA Windows GPU Display Driver contains a vulnerability in the kernel mode layer ( nvlddmkm.sys ) handler for DxgkDdiEscape where improper access controls may allow a user to access arbitrary physical memory, leading to an escalation of privileges.

CVSS Base Score: 8.8

CVSS Temporal Score: 7.7

CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C

CVE-2016-8822

NVIDIA Windows GPU Display Driver contains a vulnerability in the kernel mode layer ( nvlddmkm.sys ) handler for DxgkDdiEscape 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.

CVSS Base Score: 8.8

CVSS Temporal Score: 7.9

CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C
