Bochspwn Reloaded is an instrumentation module for the Bochs IA-32 emulator, similar to the original Bochspwn project from 2013. It performs taint tracking of the kernel address space of the guest operating systems, to detect the disclosure of uninitialized kernel stack/heap memory to user-mode and other data sinks. It helped us identify over 70 bugs in the Windows kernel, and more than 10 lesser bugs in Linux in 2017 and early 2018.
