CVE-2026-24249

Local code execution via untrusted data deserialization

Published Jul 1, 2026 · Updated Jul 1, 2026

Deserialization of untrusted data in NVIDIA Megatron Bridge 0.4.0 and earlier allows local users to execute code via unspecified vectors. NVIDIA has not published the affected function, deserializer, input format, or exact unsafe operation, so the concrete code-level mechanism remains undisclosed. Exploitation requires local low-privileged access and can result in code execution, privilege escalation, data modification, and information disclosure.
