## Overview

NVIDIA Spatial Intelligence Lab's (SIL) GEN3C contains an unauthenticated remote code execution vulnerability in the inference API server where the /request-inference and /seed-model endpoints deserialize raw HTTP request bodies using Python's pickle.loads() without authentication or input validation. Attackers can supply a crafted payload containing a __reduce__ gadget to the inference API port to achieve remote code execution as the inference process.

## Affected

- `GEN3C < db2ffe12ced12ddafcec5e0422ee46ce8520746b`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
