CVE-2026-24220

Code execution via unauthenticated ZeroMQ pickle deserialization

Published Jul 14, 2026 · Updated Jul 14, 2026

Unsafe deserialization in NVIDIA TensorRT-LLM 0.0 through 1.3.0rc11 allows local users to execute code through VisualGen ZeroMQ IPC. VisualGen's DiffusionRemoteClient and DiffusionExecutor configured request and response queues without HMAC authentication, allowing untrusted ZeroMQ messages to reach Python pickle deserialization. Exploitation requires high local privileges and high-complexity access to a VisualGen worker IPC channel; successful payloads execute code in the affected process context.
