CVE-2026-9030

A denial-of-service vulnerability exists in httpd service on Archer A6 v4 where the asynchronous systool instruction handlng path in httpd does not properly synchronize or safely manage concurrent systool operations. By sending crafted systool instructions through the asynchronous request path, successful exploitation may cause the httpd process or device management service to crash and may result in temporary loss of access to the web management interface or device reboot.

Summary		(es) Existe una vulnerabilidad de denegación de servicio en el servicio httpd en Archer A6 v4 donde la ruta de manejo de instrucciones asíncronas de systool en httpd no sincroniza adecuadamente o gestiona de forma segura las operaciones concurrentes de systool. Al enviar instrucciones systool diseñadas específicamente a través de la ruta de solicitud asíncrona, la explotación exitosa puede causar que el proceso httpd o el servicio de gestión del dispositivo se bloquee y puede resultar en la pérdida temporal de acceso a la interfaz de gestión web o el reinicio del dispositivo.
