CVE-2025-23246
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 software for Windows and Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it allows a guest to consume uncontrolled resources. A successful exploit of this vulnerability might lead to denial of service.
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 software contains a vulnerability in the Virtual GPU Manager where a guest virtual machine can consume uncontrolled resources, potentially leading to resource exhaustion and denial of service on the host system or other VMs.

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.
-
Confirm NVIDIA vGPU software is installedOn the hypervisor host, check for the presence of NVIDIA vGPU Manager by running: lsmod | grep nvidia or checking the NVIDIA software package installation (e.g., dpkg -l | grep nvidia-vgpu on Linux, or check Programs and Features on Windows).Affected if NVIDIA vGPU software is not installed on the system.
-
Identify the Virtual GPU Manager versionRun nvidia-smi -v or check the NVIDIA vGPU Manager package version on the hypervisor (e.g., nvidia-vgpu-*.rpm/.deb, or the driver version shown in nvidia-smi output under Driver Version).Affected if The installed Virtual GPU Manager version falls within an affected version range (compare your version against NVIDIA's published affected versions for CVE-2025-23246).
-
Verify vGPU functionality is enabledCheck if any VMs are configured with vGPU devices. On the hypervisor, list active vGPU assignments: virsh list --all and inspect VM XML configs for vGPU device entries (like <mdev type='nvidia-...'/>), or check VMware/Hyper-V vGPU allocation settings.Affected if vGPU pass-through or virtual GPU devices are assigned to guest virtual machines.
-
Check resource quota configurationReview the hypervisor's vGPU resource quota or scheduling settings. On Citrix Hypervisor, check xenpmg pool配置; on VMware, check the vGPU profile resource settings; on KVM, check any cgroup or libvirt vGPU resource limits configured.Affected if No resource quotas or limits are configured for vGPU consumption, allowing unbounded guest resource usage.
A system is affected if it runs a vulnerable version of NVIDIA Virtual GPU Manager with vGPU functionality enabled and without resource quota limits configured, allowing a guest VM to potentially exhaust host 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 dataApply NVIDIA vGPU software updates when available and implement proper vGPU resource quota configurations in the hypervisor to limit guest resource consumption.
