CVE-2025-23314
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA NeMo Framework for all platforms contains a vulnerability in the NLP component, where malicious data created by an attacker could cause a code injection issue. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA NeMo Framework's NLP component contains a code injection vulnerability where maliciously crafted input data can be leveraged to inject and execute arbitrary code. Successful exploitation could allow an attacker to achieve code execution, escalate privileges, disclose sensitive information, or tamper with data within the affected system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed NeMo versionRun `pip show nemo` or `pip show nemo-framework` to retrieve the installed version number. If using a container, check the image manifest or label.Affected if The installed version is below 2.4.0 (e.g., 2.3.0, 2.2.0, etc.)
-
Confirm NLP component is in useInspect your codebase or pipeline configuration for imports or usage of NeMo NLP modules such as `nemo.collections.nlp` or related tokenizers, language models, or text processing pipelines.Affected if The NLP component from NeMo is actively imported or instantiated in your environment
-
Verify input source handlingReview data ingestion points where external or untrusted text data enters the NLP pipeline, such as API endpoints, file uploads, or streaming inputs that feed into NeMo NLP models.Affected if The NLP pipeline processes input from untrusted or external sources without strict validation applied beforehand
-
Check for input sanitization implementationAudit the code that passes data to NeMo NLP models for the presence of input validation or sanitization routines. Look for explicit checks on text input before model inference.Affected if No input validation or sanitization is performed on data passed to the NLP component, or such checks are absent from the pipeline
You are affected if NeMo version is below 2.4.0 and your system processes untrusted external input through the NLP component without validation.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.4.0
Apply the NVIDIA-provided patch when available. In the interim, implement strict input validation and sanitization on all data entering the NLP pipeline, and restrict network access to services processing untrusted input.
2.4.0
- Check current Nemo installation version using 'pip show nemo' or your package manager
- Upgrade Nemo to version 2.4.0 or later using your package manager (e.g., pip install --upgrade nemo==2.4.0 or conda install nemo=2.4.0)
- After upgrade, verify the NLP component is functioning correctly and test your pipelines
- Ensure any custom code or configurations that interact with the NLP component are reviewed for compatibility
