CVE-2025-33226

Local code execution via untrusted deserialization

Published Dec 16, 2025 · Updated Dec 16, 2025

Deserialization of untrusted data in NVIDIA NeMo Framework before 2.5.3 allows local users to execute code through malicious data. NVIDIA has not published the affected component, function, data format, or unsafe deserialization operation. Exploitation requires local low-privileged access but no user interaction, and successful execution can disclose or alter data and elevate privileges.
