CVE-2026-24245

Local code execution through unsafe deserialization

Published Jul 1, 2026 · Updated Jul 1, 2026

Deserialization of untrusted data in NVIDIA Megatron Bridge before 0.4.1 allows local users to execute code through crafted input. NVIDIA has not disclosed the affected loader or the operation that deserializes attacker-controlled content, and public release notes list several separate deserialization hardenings without mapping this CVE to one change. Exploitation requires a user to load the malicious input locally; successful execution runs with that user's privileges and permits data disclosure or tampering.
