CVE-2026-102165
HighCVSS 7.5Summary
Arista Wi-Fi access points contain a vulnerability in the capture service. An unauthenticated attacker with network access can send a crafted packet to crash the service or potentially achieve remote code execution. This requires an uncommon non-default streaming mode.
Risk Assessment
The risk includes service disruption or device compromise. The attack is only possible in a specific configuration but could lead to system integrity compromise.
Recommendation
Upgrade firmware to a patched version. Also disable unused streaming modes and restrict access to the service.
Other vulnerabilities in Arista Wi-Fi access points
See all- CVE-2026-102169Medium
On affected Arista Wi-Fi access points with Captive Portal enabled, an unauthenticated wireless client can crash the portal service with a crafted HTTP request. The service restarts automatically, but a sustained low-rate attack can cause persistent denial of service. Remote code execution is not possible.
- CVE-2026-102168Medium
On affected Arista Wi-Fi access points with Captive Portal enabled, an unauthenticated wireless client can crash the portal service with a crafted HTTP request. This results in temporary denial of service until the service restarts automatically. Remote code execution is not possible.
- CVE-2026-102167High
Arista Wi-Fi access points contain a memory corruption vulnerability in the wired uplink network endpoints. An unauthenticated attacker on the same network segment can crash the sensor service or potentially achieve remote code execution.
- CVE-2026-102162High
Arista Wi-Fi access points with captive portal or application firewall enabled on at least one SSID contain a vulnerability in the wireless gateway service. An unauthenticated network-adjacent attacker can send a crafted packet that triggers a stack overflow, resulting in a denial-of-service condition or potentially execute arbitrary code on the device.
