CVE-2021-1062
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 an input data length is not validated, which may lead to tampering of data or 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 · high confidenceNVIDIA vGPU manager contains an input validation vulnerability in the vGPU plugin where input data length is not properly checked. This could allow an attacker to manipulate input data or cause denial of service by sending specially crafted requests with incorrect length parameters.

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 installed vGPU Manager versionUse the hypervisor's package management or software listing command to find the NVIDIA vGPU Manager package version. On ESXi, run 'esxcli software vib list | grep -i nvidia'. On Linux-based hypervisors, use 'rpm -qa | grep -i vgpu' or 'dpkg -l | grep -i nvidia' depending on the package manager.Affected if The installed version falls within >= 8.0 and < 8.6, OR >= 11.0 and < 11.3
-
Confirm vGPU plugin is activeCheck if the vGPU plugin or driver component is loaded and active on the hypervisor host. On ESXi, run 'esxcfg-nics -l' or check the NVIDIA driver status. On other hypervisors, verify the nvidia-vgpu or vgpu service is running.Affected if The vGPU plugin is loaded and operational, enabling the vulnerable code path to be reachable
-
Verify vGPU virtual machine configurationList any VMs that have vGPU devices assigned. On ESXi, use 'vim-cmd vmsvc/getallvms' and check VM configuration for vGPU profile assignment. Confirm vGPU profiles are configured for any guest VMs.Affected if Any VMs are configured with vGPU profiles, indicating the vulnerable input handling code is exercised during vGPU operations
You are affected if the installed vGPU Manager version is 8.0 through 8.5.x or 11.0 through 11.2.x AND the vGPU plugin is enabled or any VMs use vGPU profiles.

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
Update NVIDIA vGPU manager to version 8.6 or later (for 8.x branches) or version 11.3 or later (for 11.0 branch) to incorporate the missing input length validation.
