Exploring a New Class of Kernel Exploit Primitive

The security landscape is dynamic, changing often and as a result, attack surfaces evolve. MSRC receives a wide variety of cases spanning different products, bug types and exploit primitives. One particularly interesting primitive we see is an arbitrary kernel pointer read. These often happen whe...
