Excited to share our research on Kernel Streaming! We discovered several vulnerabilities in it that we used at Pwn2Own this year.

Thanks @BlackHatEvents for the #BHUSA acceptance! It's pure web hacking research this time! 🔥

However, I'm still not sure if I can enter the US or not. In advance, I reapplied for the VISA and had the interview in March. Two months have passed, and my case is still under review. I really want to be back on stage. Is there any effort or help I can try? 😫

I'm probably lagged but just found this website is pretty good for learning kernel exploitation! https://t.co/ErVChPhncC

@JinBlackx I didn't know there's a UAF bug until now.. And yes there are deadlock bugs.
