Privileged information disclosure via uncleared resource reuse
Published Nov 25, 2025 · Updated Nov 25, 2025
Information disclosure in NVIDIA DGX Spark before OTA0 allows local users with high privileges to read residual SROOT firmware data. SROOT firmware reuses a resource without removing sensitive information left by its prior use, exposing residual data to the next privileged consumer. Exploitation requires local access and high privileges; the published impact is limited to information disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
