CVE-2025-33198

Local information disclosure via reused firmware resource

Published Nov 25, 2025 · Updated Nov 25, 2025

Information disclosure in SROOT firmware in NVIDIA DGX Spark before OTA0 allows local users to read residual resource data. SROOT makes a firmware-managed resource available for reuse without first removing sensitive information left by its prior use. Exploitation requires local low-privilege access and affects confidentiality only; NVIDIA has not identified the resource type or trigger path.
