NVIDIA has issued a security bulletin disclosing three high-severity vulnerabilities in its NeMo Framework, a scalable, cloud-native generative AI platform designed for developers working with Large Language Models (LLMs), Multimodal Models (MMs), Speech Recognition (ASR), Text-to-Speech (TTS), and Computer Vision (CV).
Each of the vulnerabilities carries a CVSS base score of 7.6, indicating serious risks that could allow remote code execution and data tampering if successfully exploited.
The first flaw, CVE-2025-23249, involves unsafe deserialization. According to NVIDIA, the NeMo Framework: “contains a vulnerability where a user could cause a deserialization of untrusted data by remote code execution. A successful exploit of this vulnerability might lead to code execution and data tampering.”
Deserialization attacks can allow attackers to manipulate serialized objects and execute malicious code during the rehydration process—making this flaw particularly dangerous in collaborative or distributed AI development environments.
The second vulnerability, CVE-2025-23250, results from inadequate restrictions on file pathnames: “An attacker could cause an improper limitation of a pathname to a restricted directory by an arbitrary file write. A successful exploit… might lead to code execution and data tampering.”
This weakness can allow adversaries to overwrite sensitive files or introduce malicious configurations—potentially hijacking training pipelines or poisoning datasets in AI workflows.
The third vulnerability, CVE-2025-23251, impacts the code generation process itself: “A user could cause an improper control of generation of code by remote code execution. A successful exploit of this vulnerability might lead to code execution and data tampering.”
This flaw is especially concerning in generative AI environments where the boundary between trusted and untrusted code can be blurry.
NVIDIA has released an updated version of the NeMo Framework to address these security concerns. The updated version is 25.02. Users of the NVIDIA NeMo Framework are strongly advised to update to version 25.02 as soon as possible to mitigate the risks associated with these vulnerabilities.
