Description Guilherme de Almeida Suckevicz 2021-10-05 14:02:51 UTC
'Specifically timed and handcrafted traffic can cause internal errors 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' in certain Atherons based chipsets.  THis could allow an attacker to infer previous keys
