CVE-2024-0127
📋 TL;DR
This vulnerability in NVIDIA vGPU software allows a guest OS user with kernel access to exploit improper input validation in the GPU kernel driver. Successful exploitation could lead to code execution, privilege escalation, data tampering, denial of service, or information disclosure. Organizations using NVIDIA vGPU software on supported hypervisors are affected.
💻 Affected Systems
- NVIDIA vGPU software
⚠️ 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).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the vGPU Manager leading to host escape, full control of the hypervisor, and compromise of all virtual machines on the host.
Likely Case
Guest-to-host escape allowing attacker to compromise the hypervisor and potentially other VMs on the same host, leading to data theft and service disruption.
If Mitigated
Isolated impact limited to the compromised guest VM if proper network segmentation and access controls are implemented.
🎯 Exploit Status
Requires guest OS kernel compromise as prerequisite; exploit chain complexity depends on initial guest access
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check NVIDIA security bulletin for specific fixed versions
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5586
Restart Required: Yes
Instructions:
1. Review NVIDIA security bulletin 2. Download appropriate vGPU software update 3. Apply update to vGPU Manager 4. Restart affected hypervisor hosts 5. Verify patch installation
🔧 Temporary Workarounds
Isolate Guest VMs
allImplement strict network segmentation between guest VMs to limit lateral movement
Harden Guest OS
allApply guest OS hardening measures to prevent initial kernel compromise
🧯 If You Can't Patch
- Implement strict access controls to prevent unauthorized guest OS kernel access
- Isolate vGPU-enabled VMs on dedicated hosts with no critical workloads
🔍 How to Verify
Check if Vulnerable:
Check NVIDIA vGPU software version against security bulletin; vulnerable if running affected versionsCheck Version:
On hypervisor host: nvidia-smi -q | grep 'Driver Version' or check vGPU Manager versionVerify Fix Applied:
Verify vGPU software version matches or exceeds fixed version in NVIDIA advisory📡 Detection & Monitoring
Log Indicators:
- Unexpected vGPU driver errors
- Guest VM kernel privilege escalation attempts
- Hypervisor security event logs showing vGPU anomalies
Network Indicators:
- Unusual guest-to-hypervisor communication patterns
- Anomalous vGPU-related network traffic
