salt

Welcome to salt , a tool to reverse and learn kernel heap memory management. It can be useful to develop an exploit, to debug your own kernel code, and, more importantly, to play with the kernel heap allocations and learn its inner workings. This tool helps tracing allocations and the current sta...
