vGPU and Cloud Gaming: Incorrect Permission Assignment for Critical Resource

Published Updated By the CyberSecBulletin desk

CVE-2024-0128 is a high-severity incorrect permission assignment for critical resource vulnerability in vGPU and Cloud Gaming from NVIDIA, with a CVSS 3.1 base score of 7.1 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 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update virtual_gpu_manager to 16.8 or 17.4, whichever matches your release line, or a later version.
  2. Update cloud_gaming_virtual_gpu to 565.57.01 or a later version.

Official description

NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager that allows a user of the guest OS to access global resources. A successful exploit of this vulnerability might lead to information disclosure, data tampering, and escalation of privileges.

The underlying weakness: Incorrect Permission Assignment for Critical Resource

The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

How developers prevent this class of flaw

  • When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user), and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
  • Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly. This will allow you to maintain more fine-grained control over your resources.
  • During program startup, explicitly set the default permissions or umask to the most restrictive setting possible. Also set the appropriate permissions during program installation. This will prevent you from inheriting insecure permissions from any user who installs or runs the program.
