Company
Arista Networks makes cloud networking hardware and software, including high-performance switches and routers used in data centers and AI clusters.
Arista paired its 7060EX7 switches with three Ethernet rack designs, the largest reaching 1,024 accelerators in one scale-up domain across racks. Teams on non-Nvidia chips such as Microsoft's Maia, the market Arista expects to grow, get a second scale-up fabric to evaluate.
Reality
Nvidia director Mark Stevens led third-quarter insider sellers with $946.6 million of stock, ahead of Arista's Jayshree Ullal and Jeff Bezos. The three sellers' sales came to about 0.6% of their combined $302 billion fortune, so on the evidence they look more like diversification than a judgement on AI prices.
Reality
Arista's Etherlink SU-144 links up to 144 accelerators in one Ethernet hop and 1,024 across racks, built on the ESUN initiative. Arista says Nvidia-based racks stay on proprietary NVLink for now, so the open choice belongs to buyers of other accelerators.
Reality
Arista says the pre-authentication flaw is already being used against on-premises orchestrators that issue certificates to their Edge devices, and the fixed build an operator needs may not exist for their release train yet.

Check Point says a handful of its customers have already been attacked through the Security Management Server, and F5 confirmed exploitation of BIG-IP APM when it disclosed the bug on September 22.

Eclypsium tracked 158 infrastructure advisories between August 25 and September 17. The exploited maximum-severity flaws it highlights are authentication bypasses in Cisco's Firewall Management Center and Identity Services Engine.
Reality
Cornelis Networks launched a fabric that performs reductions and gradient compression in transit, and the only number attached to it, a traffic cut of up to 50%, comes from the company's own pre-production simulations.
Reality
Arista says AI-assisted bug hunting on its own code will keep its advisory volume elevated for months. Nothing in the first batch can be assessed until the CVEs and severity scores publish on September 9.
Reality
Arista scores CVE-2026-7473 at 5.8 and says it is already being exploited. With every EOS train on the affected list, the thing that decides your exposure is whether a given device terminates a tunnel at all.
Reality
CVE-2026-16812 scores 10.0 on both CVSS scales because the scope metrics say a compromise of the orchestrator host does not stay inside the orchestrator, and on-prem operators are the ones who have to schedule the fix.
