CVE-2025-23294
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 WebDataset for all platforms contains a vulnerability where an attacker could execute arbitrary code with elevated permissions. A successful exploit of this vulnerability might lead to escalation of privileges, data tampering, information disclosure, and denial of service.
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.

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.
-
Verify NVIDIA WebDataset installationCheck for WebDataset package installation using pip list, conda list, or system package manager depending on installation method. Look for package name 'webdataset' or 'nvidia-webdataset'.Affected if WebDataset is not found in the environment, the vulnerability does not apply.
-
Identify installed WebDataset versionRun 'pip show webdataset' or 'pip list | grep -i webdataset' to retrieve the installed version number. Document the exact version string.Affected if Version cannot be determined or is not documented in available version records.
-
Compare version against affected releasesCross-reference the installed version with NVIDIA security bulletins or release notes for CVE-2025-23294. Since no specific version range is provided, treat any version as potentially affected until official guidance is available.Affected if Installed version matches or predates the patched version referenced in NVIDIA's security advisory.
-
Review WebDataset execution contextExamine how WebDataset is invoked in your environment - check application code, scripts, or services that import and use the webdataset library. Look for user-controlled input paths, data loading pipelines, or deserialization operations.Affected if WebDataset processes untrusted data or operates with elevated privileges without additional security controls.
-
Audit related configuration and dependenciesInspect requirements.txt, environment files, or container definitions for WebDataset and its dependencies. Check for known vulnerable dependency versions that may be bundled.Affected if Outdated or vulnerable dependencies are present alongside WebDataset.
If NVIDIA WebDataset is installed and running with elevated privileges or processing external data, the environment is potentially affected by this arbitrary code execution vulnerability until the specific patched version is confirmed.
