CVE-2025-33188

Hardware-control tampering via improper privilege management

Published Nov 25, 2025 · Updated Nov 25, 2025

Improper privilege management in NVIDIA DGX Spark before OTA0 allows local users to tamper with GB10 hardware controls. NVIDIA identifies the locus only as hardware resources and does not disclose which control or missing privilege check permits the operation. Local access without prior privileges is sufficient; exploitation discloses information, tampers with data, or denies service by an undisclosed failure mode.
