Local code execution via untrusted deserialization
Published Sep 1, 2026 · Updated Sep 1, 2026
Untrusted-data deserialization in NVIDIA Megatron Bridge 0.0 through 0.5.0 allows local users to execute code within its process. NVIDIA has not disclosed the affected deserialization locus, accepted data format, or operation that processes attacker-controlled input. Exploitation requires low-privileged local access and no user interaction, and successful attacks can execute code, tamper with data, or disclose information in the process context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
