CVE-2026-102163: CWE-787 Out-of-bounds Write in Arista Networks Wi-Fi Access Points
Description
On affected Arista access points with Wireless Intrusion Prevention System (WIPS) active, an unauthenticated attacker within radio frequency (RF) proximity can send a crafted frame to crash the sensor service, disabling WIPS monitoring on the access point, or potentially achieve remote code execution. No wireless association or authentication is required.

Technical Analysis
This vulnerability (CWE-787) affects Arista Networks Wi-Fi Access Points running affected firmware versions with WIPS active. An attacker in RF proximity can send a crafted frame that triggers an out-of-bounds write, causing the sensor service to crash and disabling WIPS monitoring. The flaw may also allow remote code execution. Exploitation does not require authentication or association with the access point. The CVSS 3.1 base score is 8.8, indicating high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to denial of service by crashing the sensor service and disabling wireless intrusion prevention monitoring. Additionally, it may allow remote code execution, potentially compromising the device and network security. The attacker requires only RF proximity and no authentication, increasing the risk in wireless environments.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, consider disabling WIPS if feasible or restricting RF proximity to trusted environments to reduce exposure. Monitor vendor communications for official fixes or temporary mitigations.
