NemoClaw: Download of Code Without Integrity Check

Published Updated By the CyberSecBulletin desk

CVE-2026-65097 is a high-severity download of code without integrity check vulnerability in NemoClaw from NVIDIA, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected NemoClaw versions: 0 to 0.0.21. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.32% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of NemoClaw you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

NVIDIA NemoClaw for Linux contains a vulnerability in its installation scripts, where an attacker could cause a download of code without integrity check. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Download of Code Without Integrity Check

The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.

How developers prevent this class of flaw

  • Perform proper forward and reverse DNS lookups to detect DNS spoofing.
  • Encrypt the code with a reliable encryption scheme before transmitting.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
