vGPU software and Cloud Gaming: Incorrect Privilege Assignment
CVE-2024-0085 is a high-severity incorrect privilege assignment vulnerability in vGPU software and Cloud Gaming from NVIDIA, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. There is no confirmed exploitation so far. EPSS estimates a 0.12% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update virtual_gpu to 13.11 or 16.6 or 17.2, whichever matches your release line, or a later version.
- Update cloud_gaming_virtual_gpu to 555.52.04 or a later version.
- Update Cloud Gaming to 555.52.04 or a later version.
- Read the advisory on nvidia.custhelp.com for workarounds and exact fixed builds.

Official description
NVIDIA vGPU software for Windows and Linux contains a vulnerability where unprivileged users could execute privileged operations on the host. A successful exploit of this vulnerability might lead to data tampering, escalation of privileges, and denial of service.

The underlying weakness: Incorrect Privilege Assignment
A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
