hope everyone has fun playing with it~

AI is getting really useful for vuln research. With some manual guidance, I used GPT-5.4 to find some Windows kernel bugs, and the points in the image still feel obvious.
Even so, its already a fun and powerful tool in the workflow. Curious how other researchers are using it😃

Here is my writeup for 2 Windows kernel bugs I reported to MSRC. Both are race conditions that cause Use-After-Free. As there is very few windows kernel writeups I share my research methodology and more. Hope it helps other researchers. Share it😀

Recently discovered some unauthenticated RCEs~

[RyeLv @b2ahex]

@NikitaTarakanov Thanks!

[RyeLv @b2ahex]

@NikitaTarakanov Not for the time being, but it shouldn't be difficult to reproduce through patch diff

[RyeLv @b2ahex]

Sadly, the nt object reference count overflow vulnerability I reported earlier was defined as a "moderate severity, non-persistent denial of service vulnerability"
no bounty..😑

[Sungyup Nam @REDPACK_kr]

I make a BSOD of Win10 with CVE-2022-30151, which was discovered by @b2ahex and patched last week. This vulnerability is a race condition bug, which results in Double-Free. I share my scenario slide to trigger this vulnerability and a crash screenshot. Thx.

[RyeLv @b2ahex]

@REDPACK_kr wow👍
