Listen to this Post
The CVE-2025-33193 vulnerability resides within the SROOT firmware of NVIDIA DGX Spark GB10 systems, specifically involving improper validation of integrity checks. During firmware boot or update processes, the system fails to adequately verify cryptographic signatures or checksums of critical components. This flaw allows an attacker with local or network access to craft malicious inputs or tamper with firmware images. By bypassing these integrity checks, the attacker can trigger unauthorized read operations from protected memory regions or storage areas. This exploitation leads to information disclosure, where sensitive data such as encryption keys, configuration files, or proprietary information may be leaked. The vulnerability stems from insufficient validation routines in the firmware’s trusted boot chain, potentially enabling attackers to extract data without elevating privileges.
