NVIDIA vGPU software contains a vulnerability in the guest kernel mode driver and vGPU plugin, in which an input data size is not validated. This may lead to tampering of data or denial of service. The vulnerability affects vGPU versions 8.x (prior to 8.6) and version 11.0 (prior to 11.3). Given its high CVSS score of 7.1, it poses a significant risk to organizations utilizing this software.
The vulnerability's exploitation could allow unauthorized access and manipulation of critical system data, thereby compromising the integrity and availability of systems. Organizations should prioritize patching immediately.
No known exploits have been confirmed in the wild, but the potential impact is severe. The vulnerability is classified as high due to the combination of low attack complexity and the requirement for low privileges.
Organizations running affected versions of NVIDIA vGPU software should consider this vulnerability a critical issue and implement remediation strategies without delay.
Vulnerability Details
The vulnerability occurs due to insufficient validation of input data sizes within the NVIDIA vGPU software. The vulnerability is categorized under CWE-1284 and falls under the local attack vector with low complexity.
The CVSS v3.1 score of 7.1 indicates a high severity, with potential impacts on the integrity and availability of the system, while confidentiality is not affected. This highlights the critical need for organizations to address this vulnerability to protect their systems.
Technical Analysis
The root cause of this vulnerability stems from the lack of validation of input data sizes in the guest kernel mode driver and vGPU plugin. Attackers with local access can exploit it, leveraging low privileges without the need for user interaction.
The attack complexity is low, making it easier for attackers to leverage this vulnerability if they gain local access. The impact on integrity and availability is high, which can lead to significant disruption in services.
Risk & Impact Analysis
Risk to organizations includes potential data tampering and denial of service, which can critically affect operational capabilities. The blast radius of this vulnerability can be extensive if exploited, particularly in environments utilizing vGPU for virtualized graphics.
Given the growing reliance on virtualized environments, organizations must prioritize the remediation of this vulnerability as part of their security posture. The CVSS score indicates an urgent need for patching to prevent exploitation.
