NVIDIA vGPU manager contains a vulnerability in the vGPU plugin, in which input data is not validated, which may lead to unexpected consumption of resources, which in turn may lead to denial of service. This affects vGPU version 8.x (prior to 8.6) and version 11.0 (prior to 11.3).
The vulnerability has a CVSS score of 5.5, categorizing it as medium severity. The ability to exploit this vulnerability could result in significant disruption, necessitating prompt attention from security teams.
Risk to organizations includes potential denial of service that could severely impact operations. Given the nature of this vulnerability, organizations running affected versions of NVIDIA vGPU Manager should take immediate action.
As of now, there are no known public exploits or proof-of-concept code available, but the nature of the vulnerability means attackers may develop such methods over time. Organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability in NVIDIA vGPU Manager occurs due to improper validation of input data, allowing for unexpected resource consumption. The CVSS score of 5.5 indicates a medium severity level, reflecting a high impact on availability but no impact on confidentiality or integrity. The affected products are versions 8.x (prior to 8.6) and 11.0 (prior to 11.3). This vulnerability has been cataloged under CWE-20, indicating improper input validation.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper input validation within the vGPU plugin of the NVIDIA vGPU manager. This flaw can be exploited locally, requiring low privileges and no user interaction, making it relatively straightforward for an attacker with local access to exploit the vulnerability. The attack complexity is low, which increases the risk of exploitation.
The confidentiality impact is rated as none, which means that sensitive information is not disclosed. The integrity impact is also rated as none, indicating that data remains unaltered. However, the availability impact is high, representing a significant risk of service disruption.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is notable. Organizations utilizing NVIDIA vGPU Manager are at risk of service interruptions due to the denial of service potential. Given the reliance on GPU resources in many modern environments, the blast radius could affect multiple systems and services.
Organizations should address this vulnerability in their priority patch cycle. With a CVSS score of 5.5, it is classified as medium severity; however, the implications of a denial of service attack are significant enough to warrant immediate action.
