CVE-2025-33214
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 NVTabular for Linux contains a vulnerability in the Workflow component, where a user could cause a deserialization issue. A successful exploit of this vulnerability might lead to code execution, denial of service, 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 NVTabular for Linux contains a deserialization vulnerability in its Workflow component where user-controlled data can be processed unsafely during deserialization operations. This could allow an attacker to manipulate serialized data to achieve code execution, cause denial of service, disclose information, or tamper with data.

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.
-
Confirm NVIDIA NVTabular installationRun 'pip show nvt' or 'pip show nvtabular' to display installed package details, or check for the package in your Python environment using 'pip list | grep -i nvt'Affected if NVTabular/nvtabular package is present in the environment
-
Identify the installed NVTabular versionReview the version number from the package metadata obtained in the previous stepAffected if The installed version falls within a vulnerable range (compare to official NVIDIA security advisory for CVE-2025-33214)
-
Verify Workflow component usageSearch codebase or configuration for imports of 'nvtabular.workflow' module and usage of Workflow class, such as 'from nvtabular.workflow import Workflow' or workflow object instantiationAffected if The NVTabular Workflow component is being used to process data
-
Inspect serialized data intake pointsSearch for files or data streams loaded via 'workflow.load_serialized()', 'workflow.from_schema()' with serialized inputs, or pickle/cloudpickle deserialization calls in workflowsAffected if The workflow processes serialized data from untrusted or external sources
-
Check access controls on workflow input dataReview file permissions and access controls on any directories or files containing serialized workflow artifacts (.parquet, .csv, or custom serialized files used as workflow input)Affected if Serialized data processed by NVTabular is accessible to untrusted users or originates from unvalidated sources
You are affected if NVTabular with a vulnerable version is installed AND its Workflow component processes serialized data from sources with insufficient access controls.
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.
From vendor dataUpdate to the latest version of NVTabular that addresses the deserialization vulnerability. If no patch is available, review and restrict input to the Workflow component, implement input validation on serialized data, and consider using safer serialization formats such as JSON instead of pickle where possible.
