Description

The version of the NVIDIA GPU display driver installed on the remote Windows host is 340.x prior to 342.01 or 375.x prior to 376.33. It is, therefore, affected by multiple vulnerabilities :

  • A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper access controls. A local attacker can exploit this to access arbitrary memory and thereby gain elevated privileges. (CVE-2016-8821)

  • A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape IDs 0x600000E, 0x600000F, and 0x6000010 due to improper validation of user-supplied input that is used as an index to an internal array. A local attacker can exploit this to corrupt memory, resulting in a denial of service condition or an escalation of privileges. (CVE-2016-8822)

  • Multiple buffer overflow conditions exist in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper validation of an input buffer size. A local attacker can exploit these to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-8823, CVE-2016-8825)

  • A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper access controls. A local attacker can exploit this to write to restricted portions of the registry and thereby gain elevated privileges. (CVE-2016-8824)

  • A flaw exists in the nvlddmkm.sys driver that allows a local attacker to cause GPU interrupt saturation, resulting in a denial of service condition. (CVE-2016-8826)
