CVE-2021-1066
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA 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).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA vGPU manager contains an input validation vulnerability in the vGPU plugin where unvalidated input data can cause unexpected resource consumption, leading to denial of service. The issue affects vGPU versions 8.x prior to 8.6 and version 11.0 prior to 11.3.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify NVIDIA vGPU Manager installationLocate and retrieve the installed version of the NVIDIA vGPU Manager software on the hypervisor host. This may be visible in the system package manager, driver inventory, or NVIDIA control panel components.Affected if vGPU Manager is present on the system and its version falls within 8.0 to 8.5 (inclusive) or 11.0 to 11.2 (inclusive).
-
Confirm vGPU plugin is in useDetermine whether the vGPU plugin or virtual GPU functionality is enabled and actively providing virtual GPU resources to guest virtual machines. Inspect hypervisor settings, vGPU pool configuration, or VM assignment profiles.Affected if The vGPU plugin is enabled and serving vGPU resources to virtual machines, making the input validation flaw reachable.
-
Compare installed version to affected rangesTake the installed version number identified in step 1 and compare it against the vulnerable ranges: version 8.x prior to 8.6, or version 11.0 prior to 11.3.Affected if The installed version is less than 8.6 for the 8.x branch, or less than 11.3 for the 11.x branch.
-
Review resource consumption logsExamine hypervisor and vGPU service logs for any unusual or excessive resource consumption patterns, error messages, or warnings related to the vGPU plugin that may indicate exploitation of this vulnerability.Affected if Logs show unexpected resource consumption or errors originating from the vGPU plugin component.
A system is affected if NVIDIA vGPU Manager is installed with a version in the 8.0 to 8.5 range or 11.0 to 11.2 range AND the vGPU plugin is enabled and actively providing virtual GPU resources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data8.611.3
Apply the vendor patch by upgrading NVIDIA vGPU manager to version 8.6 or later (for 8.x branch) or version 11.3 or later (for 11.0 branch). Schedule maintenance windows for patching and validate vGPU functionality post-update.
