CVE-2025-33192

Firmware disclosure and service interruption via NULL dereference

Published Nov 25, 2025 · Updated Nov 25, 2025

Unchecked return-value handling in NVIDIA DGX Spark before OTA0 allows local users to read arbitrary SROOT firmware memory. The SROOT firmware fails to check a function return value before dereferencing a resulting NULL pointer, permitting the arbitrary read. Local access is required, but no privileges or user interaction are required; the bounded effects are firmware-memory disclosure and service interruption.
