MSFT released a patch for CVE-2024-30078 (Wi-Fi Driver RCE) on June cumulative update, however details on the advisory have been very limited.
I'm leaving some quick notes from a quick reverse engineering of the patch that hopefully will shed a little more light on the issue. 🧵 I am not an expert on wireless network protocols so feel free to correct me or add up on the provided info in the comments or through a DM.
The patch targets Dot11Translate80211ToEthernetNdisPacket() of the native wifi driver (nwifi.sys).

Inspired by @osxreverser analysis of NSA BPF port-knocking implant, I decided to take a 2nd look at #ShadowBrokers leak of windows implants. Lo and behold, a couple of hardly mentioned kernel drivers (#DoormanGauze and #FlewAvenue) caught my attention. (1/11) Information publicly available on these drivers is scarce and for the most part flat out wrong. Instead of going for the usual deep-dive blog post, lets try a light-speed tweeter thread analysis. In this thread we'll take a brief look at #DoormanGauze. (2/11)
