Summary

Arista Networks Wi-Fi access points from 22.0.0 through 22.0.1F-32, from 21.3.0 through 21.3.0M-13, and from 1.0.0 before 21.3.0 contain a memory corruption flaw in the wired uplink network endpoints, classified as a stack-based buffer overflow (CWE-121). An unauthenticated attacker on the same network segment as the access point's wired uplink can crash the sensor service or potentially execute code remotely.

Description from the CNA

On affected Arista Wi-Fi access points, a memory corruption vulnerability exists in access point's wired uplink network endpoints. An unauthenticated attacker can crash the sensor service or potentially achieve remote code execution. Exploitation requires the attacker to be on the same network segment as the access point's wired uplink.
