Overview

As part of Arista’s ongoing commitment to security and transparency, we are providing advance notice for multiple Security Advisories scheduled for publication on September 09, 2026.

Background

Recent enhancements to our vulnerability detection processes have resulted in a higher-than-usual volume of security updates. Arista is providing this advance notification to help our customers plan. To streamline remediation efforts and allow customers to address them in a consolidated maintenance window, Arista is consolidating a larger volume of discrete advisories into aggregated bulk advisory releases. For more information about Arista’s Vulnerability Management process, see Device Hardening and Vulnerability Management.

Scope of the Upcoming Release

We expect multiple advisories to be included in this upcoming release, affecting Arista EOS and VeloCloud.

Next Steps for Our Customers

This notice is intended solely to help you prepare for the upcoming releases.  Customers are encouraged to subscribe to notifications on new software releases and be ready to begin testing once advisories are available.

On September 09, 2026, the full details of each advisory—including specific CVE information, severity scores, affected versions, and remediation instructions—will be published here on the Arista Advisories and Notices page. This document will be updated as more information becomes available.
