CVE-2025-23353

Local code execution via preprocessing data injection

Published Sep 24, 2025 · Updated Sep 24, 2025

Code injection in NVIDIA Megatron-LM before 0.13.1 and 0.12.3 allows local users to execute code through malicious preprocessing data. The msdp preprocessing script accepts attacker-created data in an injection path, but NVIDIA has not disclosed the unsafe operation or input field. A low-privileged local account is required; successful exploitation runs code with the script's privileges and can expose or alter data.
