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.
Broadcom no longer supports their hardware on any Windows platforms. As such there is no security update available to address this vulnerability. We recommend that customers using HoloLens 1 devices with this WiFi client device do the following to protect themselves from this vulnerability:
