On April 22, 2025, NVIDIA released security patches and advised users to update immediately to prevent potential exploitation on Windows, Linux, and macOS.
High-Severity Vulnerabilities in NVIDIA NeMo Framework:
CVE-2025-23249 is a vulnerability that permits unsafe deserialization of untrusted data, enabling attackers to execute arbitrary code remotely.
CWE-502 allows attackers to manipulate serialized objects and inject malicious code during data processing.
“NVIDIA 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,” states the official security bulletin.
The second vulnerability (CVE-2025-23250) involves improper path validation (CWE-22), allowing attackers to exploit path traversal techniques to write arbitrary files.
Security researchers warn that this vulnerability may let attackers overwrite sensitive files or alter configurations, which could disrupt training pipelines or contaminate datasets in AI processes.
The third vulnerability (CVE-2025-23251) involves improper code generation control (CWE-94) that could allow for remote code execution.
This is particularly worrying for a framework meant for generative AI, as it affects the line between trusted and untrusted code execution.
NVIDIA acknowledged security researcher Peng Zhou from Shanghai University for reporting three vulnerabilities in April.
All three vulnerabilities share the same attack vector specifications (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:L), indicating they can be exploited remotely with low attack complexity and no privileges required, though user interaction is needed.
The NeMo Framework is a scalable, cloud-native AI platform used by researchers and developers for large language models, multimodal models, and AI applications like speech recognition and computer vision.
The company released version 25.02 to fix these issues and urges all affected systems to update immediately.
