Abstract
Memory corruption detection technologies are described. A processor can include a memory to store a memory corruption detection (MCD) table. A processor core of the processor can receive, from an application, an allocation request for an allocation of a memory object within a contiguous memory block in the memory. The processor core can allocate the contiguous memory block in view of a size of the memory object requested and write MCD meta-data into the MCD table, including a MCD identifier (ID) associated with the contiguous memory block and a MCD border value indicating a size of a memory region of the contiguous memory block.
