This patch day, Microsoft introduced new garbage collection mechanism in win32k. In addition to the previously introduced type isolation mechanism, there is now garbage collection, making it more difficult to control the heap feng shui.

My VR journey so far is like 4 bugs, 1 doesn't work on the latest version due to unknown fix my MS, 1 bug found by XYZ person at Pwn2Own, 1 bug reported by someone else a bit before me and a new bug that seems to be un-exploitable :( Sucks to the core but gotta keep going !

My first coin ! A year ago even in my dreams I could have never imagined getting myself one. Had only seen others getting such things. A huge thing for me and something I'm never gonna forget in my life. Thanks to Google for making this happen. Security Research ❤️
