CVE-2025-23284

7.8 HIGH

📋 TL;DR

This vulnerability in NVIDIA vGPU software allows a malicious guest virtual machine to trigger a stack buffer overflow in the Virtual GPU Manager. Successful exploitation could lead to code execution, denial of service, information disclosure, or data tampering. Organizations using NVIDIA vGPU technology in virtualized environments are affected.

💻 Affected Systems

Products:
  • NVIDIA vGPU software
Versions: Multiple versions prior to the security update
Operating Systems: Linux (vGPU host platforms)
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects environments using NVIDIA vGPU technology with guest VMs that have vGPU capabilities.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full compromise of the host system through remote code execution, allowing attacker to access all guest VMs, steal data, or deploy ransomware.

🟠

Likely Case

Denial of service affecting vGPU functionality and potentially crashing the hypervisor, disrupting multiple virtual machines.

🟢

If Mitigated

Isolated impact limited to the affected guest VM if proper segmentation and least privilege controls are implemented.

🌐 Internet-Facing: LOW - This vulnerability requires access to a guest VM within the virtualized environment, not directly internet-exposed.
🏢 Internal Only: HIGH - Malicious insiders or compromised internal systems with guest VM access could exploit this to escalate privileges.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires guest VM access and knowledge of the vulnerability. No public exploits are currently available.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Refer to NVIDIA security bulletin for specific patched versions

Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5670

Restart Required: Yes

Instructions:

1. Review NVIDIA security bulletin for affected versions. 2. Download and install the updated vGPU software from NVIDIA. 3. Restart the hypervisor host system. 4. Verify guest VMs are functioning correctly.

🔧 Temporary Workarounds

Isolate vGPU-enabled VMs

all

Segment vGPU-enabled virtual machines onto separate hosts from critical infrastructure

Restrict vGPU access

all

Limit vGPU assignments to trusted guest VMs only and implement strict access controls

🧯 If You Can't Patch

  • Implement network segmentation to isolate vGPU hosts from critical systems
  • Enhance monitoring of vGPU host systems for unusual activity or crashes

🔍 How to Verify

Check if Vulnerable:

Check NVIDIA vGPU software version against the security bulletin. Run: nvidia-smi -q | grep 'Driver Version'

Check Version:

nvidia-smi -q | grep 'Driver Version'

Verify Fix Applied:

Verify installed vGPU software version matches or exceeds the patched version listed in the NVIDIA advisory

📡 Detection & Monitoring

Log Indicators:

  • Hypervisor crashes or instability
  • vGPU service failures
  • Unexpected guest VM behavior with vGPU access

Network Indicators:

  • Unusual network traffic from vGPU hosts
  • Connection attempts to vGPU management interfaces from guest VMs

SIEM Query:

source="hypervisor_logs" AND (event="crash" OR event="vGPU_error") OR source="guest_vm_logs" AND process="nvidia" AND event="exception"
