Abstract

Memory corruption detection technologies are described. A processor can include a memory to store data from an application, wherein the memory comprises a memory corruption detection (MCD) table. The processor can also include processor core coupled to the memory. The processor core can receive, from an application, a memory access request to access data of one or more contiguous memory blocks in a memory object of the memory. The processor core can also retrieve data stored in the one or more contiguous memory blocks based on the location indicated by the pointer. The processor core can also retrieve, from the MCD table, allocation information associated with the one or more contiguous memory blocks. The processor core can also send, to the application, a fault message when a fault event associated with the retrieved data occurs based on the allocation information.
