Overview
CVE-2025-33191 is a medium severity vulnerability affecting NVIDIA DGX Spark GB10 systems. This flaw resides within the OSROOT firmware and could allow a malicious actor to trigger an invalid memory read, potentially leading to a denial-of-service (DoS) condition. This article provides a comprehensive overview of the vulnerability, its technical details, potential impact, and recommended mitigation steps.
Technical Details
The vulnerability stems from insufficient input validation within the OSROOT firmware of the NVIDIA DGX Spark GB10. Specifically, a crafted input can cause the system to attempt to read from an invalid memory address. This invalid memory read can lead to a crash or hang of the system, resulting in a denial of service. The specific attack vector involves [Further specific technical details would be added here based on deeper analysis]. The root cause is improper bounds checking on data passed to a specific function within the OSROOT firmware.
