CVE-2025-33199

Data tampering via incorrect firmware control flow

Published Nov 25, 2025 · Updated Nov 25, 2025

Incorrect control flow in SROOT firmware in NVIDIA DGX Spark before OTA0 allows local users with high privileges to tamper with data. NVIDIA identifies SROOT firmware as the locus but has not disclosed the faulty control-flow path or the input that reaches it. Exploitation requires local access and high privileges; the reported consequence is limited to integrity loss through data tampering.
