CVE-2025-23348

Local code execution via crafted training data

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 training data. NVIDIA identifies the pretrain_gpt script but has not disclosed which parser or evaluator generates code from the crafted input. Exploitation requires local low-privileged access and delivery of the data to that script; successful execution can disclose or alter data and escalate privileges.
