1) Denial of service

EUVDB-ID: #VU1120

Risk: Medium

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2016-7390

CWE-ID: CWE-129 - Improper Validation of Array Index

Exploit availability: Yes

Description

The vulnerability allows a local user to cause DoS condition or gain elevated privileges on the target system.
The weakness exists due to insufficient array index validation  in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x7000194,that allows a local attacker to trigger denial of service or increase privileges.
Successful exploitation of the vulnerability may result in denial of service or privilege escalation.

Mitigation

Update Quadro and NVS to 342.00, 375.63.
Update GeForce to 375.63.
