CVE-2026-24157
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 contains a vulnerability in checkpoint loading where an attacker could cause remote code execution. 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 contains a critical vulnerability in its checkpoint loading mechanism that allows remote code execution. The vulnerability stems from insufficient validation or insecure handling during the checkpoint loading process, enabling attackers to execute arbitrary code with the privileges of the running application.

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 NeMo Framework versionRun 'pip show nemo' or check the installed package version using your Python package managerAffected if The installed version is lower than 2.6.2
-
Locate checkpoint loading codeSearch for code that imports or uses checkpoint loading modules such as 'from nemo.utils import checkpoint' or similar checkpoint-related imports in your applicationAffected if Checkpoint loading functionality is present in the environment
-
Verify checkpoint sourcesReview configuration files and environment variables that specify checkpoint file paths or URLs (e.g., checkpoint_dir, checkpoint_path, model_path settings)Affected if Checkpoint loading sources are not restricted to explicitly trusted locations or network sources are allowed
-
Inspect deserialization behaviorMonitor or log the checkpoint loading process to observe if arbitrary code execution occurs during deserializationAffected if The application deserializes checkpoint files without additional validation beyond the framework's built-in mechanisms
-
Check for network exposureReview whether the NeMo service or API that loads checkpoints is exposed to untrusted networks or accepts checkpoint paths from user inputAffected if Checkpoint loading accepts input from untrusted sources or is accessible to unauthorized users
A defender is affected if their NeMo Framework version is below 2.6.2 AND the checkpoint loading feature is actively used with untrusted or external checkpoint sources.
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 · scoped2.6.2
Apply NVIDIA's official patch for NeMo Framework as soon as it becomes available. As a temporary measure, restrict checkpoint loading to trusted sources and implement additional input validation around checkpoint deserialization.
NeMo Framework 2.6.2
- Identify current NeMo Framework version in use
- Review release notes for 2.6.2 to understand changes
- Plan upgrade scheduling and testing approach
- Backup existing configurations and checkpoints
- Upgrade NeMo to version 2.6.2 or later
- Verify installation and test checkpoint loading functionality
