Security Responses and Updates

NVIDIA believes in the Linux model of security through transparency. NVIDIA constantly monitors security advisories and provides updated packages and notifies users when major vulnerabilities affect Cumulus Linux.

Subscribe to the Cumulus Networks Security Announcements mailing list so you can receive notification from NVIDIA whenever the team discovers a security issue.

NVIDIA tracks all security issues on the mailing list and references them in this article.

Security Policy

Because Cumulus Linux is based on Debian, NVIDIA will, within a reasonable time frame, address security problems that adhere to the Debian policies in place.

Every Cumulus Linux release includes all applicable security patches available before the build date. NVIDIA evaluates any new vulnerabilities listed by Debian after the release and addresses them in a package update in the Cumulus Linux repository.

Upgrading Cumulus Linux for Security Updates

When NVIDIA or issue a critical security update, NVIDIA updates Cumulus Linux and describes the nature of the update in an article in the Security section of the knowledge base. NVIDIA adds other security fixes to the Cumulus Linux repositories without announcements (Debian announces all security updates).

If the article does not specify a procedure for upgrading Cumulus Linux, follow these steps instead:

  1. Run apt-get update.
  2. Run apt-get upgrade.

Do not install security patches from Debian directly unless you have consulted with NVIDIA directly.

Discovering Security Issues

Users who become aware of a security vulnerability in Cumulus Linux should contact NVIDIA with details of the vulnerability. Send descriptions of any vulnerabilities to

Any vulnerability reported through customers, and not yet reported by Debian get reported to the Debian security team ( or As a result, a bug gets filed in Debian BTS with a tag of security.

In addition, NVIDIA works in conjunction with Debian’s security team to resolve the issue and publish an advisory as quickly as possible.
