CVE-2026-53805Public exploitNetwork attack vector

Unauthenticated code execution via pickle deserialization

Published Jun 17, 2026 · Updated Jun 17, 2026

Unsafe deserialization in NVIDIA GEN3C before commit db2ffe1 allows remote attackers to execute code through its inference API. The /request-inference and /seed-model handlers pass raw HTTP bodies to pickle.loads(), allowing a reduce gadget to run during decoding. Any client that can reach the unauthenticated API port can run commands and access or alter data available to the inference process, or interrupt that process.
