Descriptions
An issue was discovered on Broadcom Wi-Fi client devices. Specifically timed and handcrafted traffic can cause internal errors (related to state transitions) in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for a discrete set of traffic, a different vulnerability than CVE-2019-9500, CVE-2019-9501, CVE-2019-9502, and CVE-2019-9503.
Se detectó un problema en los dispositivos cliente de Broadcom Wi-Fi. Específicamente un tráfico diseñado minuciosamente y sincronizado puede causar errores internos (relacionados con las transiciones de estado) en un dispositivo WLAN que conllevan a un cifrado de Wi-Fi de Capa 2 inapropiado con una consiguiente posibilidad de divulgación de información por medio del aire para un conjunto de tráfico discreto, una vulnerabilidad diferente de CVE-2019-9500, CVE-2019-9501, CVE-2019-9502 y CVE-2019-9503.
