Descriptions
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.
Se presenta una vulnerabilidad de denegación de servicio explotable en el kernel de Linux anterior a mainline 5.3. Un atacante podría explotar esta vulnerabilidad al activar AP para enviar actualizaciones de ubicación IAPP para las estaciones antes de que el proceso de autenticación requerido haya sido completado. Esto podría conllevar a diferentes escenarios de denegación de servicio, bien sea causando ataques de tabla CAM o provocando aleteo de tráfico si falsifica clientes ya existentes en otros AP cercanos de la misma infraestructura inalámbrica. Un atacante puede falsificar paquetes de Petición de Autenticación y Asociación para activar esta vulnerabilidad.
A flaw was found in the Linux kernel’s implementation of the WiFi station handoff code. An attacker within the radio range could use this flaw to deny a valid device from joining the access point.
