Denial of service in nVidia NVS

1) Denial of service

EUVDB-ID: #VU1123

Risk: Medium

CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2016-7388

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a local user to cause DoS condition or gain elevated privileges on the target system.
The weakness exists due to improper input validation in the kernel mode layer (nvlddmkm.sys) handler. By sending an invalid content, a local attacker can cause NULL pointer dereference, leading to denial of service or an escalation of 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.
