Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.41% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs NVIDIA NemoClaw and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

NVIDIA NemoClaw for Linux contains a vulnerability in its installation process, where an attacker could cause execution of untrusted code. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, information disclosure, and denial of service.

What

NVIDIA NemoClaw for Linux contains a vulnerability in its installation process, where an attacker could cause execution of untrusted code. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, information disclosure, and denial of service.

Why

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

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may obtain information outside the intended access boundary.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-494 ↗

CWE-494: 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.

?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

Official EUVD record ↗
CSIRT Italia · Italian · risolte-vulnerabilita-in-prodotti-nvidia-2Risolte vulnerabilità in prodotti NVIDIA

Aggiornamenti di sicurezza NVIDIA risolvono 28 vulnerabilità, di cui 2 con gravità "critica" e 17 con gravità "alta", che interessano i prodotti NemoClaw, OpenShell, Unified Fabric Manager (UFM) Enterprise e DGX Spark. Tali vulnerabilità, qualora sfruttate, potrebbero consentire a un utente malintenzionato di eseguire codice arbitrario, elevare i propri privilegi, alterare i dati, accedere a informazioni sensibili e compromettere la disponibilità dei sistemi interessati.

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Patch available
Affected
NemoClaw: 0 to 0.0.21
Fixed
An authoritative update reference is available, but the fixed version is not recorded in the structured CVE fields. Check the linked vendor advisory for the applicable release.
Action
Review the linked authoritative reference and apply the recorded fixed release appropriate to the affected product branch.
Workaround
No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
