Key GPU Vulnerabilities & Exploits

1. NVIDIAScape: Critical Container Escape in NVIDIA Container Toolkit — CVE-2025-23266

A Container Escape vulnerability in NVIDIA's Container Toolkit allows a malicious container to gain root access to the host, bypassing isolation with just a few lines of Dockerfile code.

• CVSS: 9.0 (Critical)

• Affects: Up to 37% of cloud GPU environments.

• Mitigation: Update to version 1.17.8 (Container Toolkit) or 25.3.1 (GPU Operator).

2. Local Driver Vulnerabilities in NVIDIA Display Drivers — Multiple CVEs

A batch of GPU driver flaws was patched in July 2025, including:

• CVE-2025-23276: Privilege escalation via installer.

• CVE-2025-23277: Out-of-bounds memory access.

• CVE-2025-23278: Improper index validation.

• CVE-2025-23279 & 23281: Race condition and use-after-free attacks enabling system compromise.

• CVE-2025-23283/2-23284: vGPU buffer overflow vulnerabilities.

5. GPUHammer: Rowhammer-Style Bit-Flipping Attack in VRAM

Researchers demonstrated bit-flip attacks targeting GPU VRAM (e.g., RTX A6000), drastically degrading AI model accuracy from 80% to 0.1%—without modifying code.

• Affects Ampere, Ada, Hopper, Turing architectures.

• Defense: Enable Error Correction Code (ECC) memory.

Proactive Mitigation Guide by CyberDudeBivash

• Patch Immediately

  • Apply updates for Triton, container toolkit, and GPU drivers promptly.

  • Mobile users should install August 2025 security updates.

• Architectural Hygiene

  • Isolate containers with GPU-critical workloads in secure FIPS-compliant environments.

  • Restrict access to Triton servers and monitor management consoles.

• Enable ECC Memory

  • Use ECC-enabled GPUs to guard against VRAM bit-flip attacks like GPUHammer.

• Threat Detection

  • Deploy CrowdStrike Falcon to detect kernel-level compromise attempts.

  • Integrate Threat Analyser App to flag suspicious driver/system behavior.

• Secure Mobile Ecosystems

  • Enforce OEM GPU driver patches via fleet management systems.

  • Raise awareness on GPU-related security in mobile device management.
