CVE-2023-25515

7.8 HIGH

📋 TL;DR

This vulnerability in NVIDIA GPU display drivers allows attackers to execute arbitrary code, escalate privileges, or cause denial of service by sending specially crafted untrusted data to the driver. It affects Windows and Linux systems with vulnerable NVIDIA GPU drivers installed.

💻 Affected Systems

Products:
  • NVIDIA GPU Display Driver
Versions: Multiple versions prior to security updates released in February 2023
Operating Systems: Windows, Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Affects both consumer and professional GPU lines; specific version ranges vary by product line and OS.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with kernel-level code execution leading to complete data theft, ransomware deployment, or persistent backdoor installation.

🟠

Likely Case

Local privilege escalation allowing attackers to gain administrative access on compromised systems, potentially leading to lateral movement within networks.

🟢

If Mitigated

Limited impact with proper network segmentation, least privilege access controls, and endpoint protection that blocks driver-level exploits.

🌐 Internet-Facing: LOW - This is primarily a local vulnerability requiring access to the system, though could be combined with other exploits in attack chains.
🏢 Internal Only: HIGH - Significant risk for internal systems where attackers could gain initial access through phishing or other means and then escalate privileges.

🎯 Exploit Status

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

Requires local access or ability to execute code on target system; exploitation involves parsing untrusted data through vulnerable driver interfaces.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Varies by product line - check NVIDIA security bulletin for specific version numbers

Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5468

Restart Required: Yes

Instructions:

1. Visit NVIDIA Driver Downloads page 2. Select your GPU model and OS 3. Download latest driver version 4. Run installer with administrative privileges 5. Restart system when prompted

🔧 Temporary Workarounds

Restrict GPU driver access

all

Limit which users and applications can interact with GPU drivers through system policies

Disable unnecessary GPU features

all

Turn off GPU acceleration for non-essential applications to reduce attack surface

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate systems with vulnerable drivers
  • Apply principle of least privilege and monitor for privilege escalation attempts

🔍 How to Verify

Check if Vulnerable:

Check NVIDIA driver version against affected versions listed in security bulletin ID 5468

Check Version:

Windows: nvidia-smi | findstr "Driver Version" | Linux: nvidia-smi --query-gpu=driver_version --format=csv

Verify Fix Applied:

Verify driver version matches or exceeds patched version specified in NVIDIA advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual GPU driver process activity
  • Privilege escalation attempts
  • Suspicious driver-level API calls

Network Indicators:

  • Lateral movement from systems with vulnerable drivers
  • Command and control traffic following local compromise

SIEM Query:

EventID=4688 AND ProcessName contains "nvidia" AND ParentProcess NOT IN (expected_parent_processes)
