Abstract:
Memory corruption detection technologies are described. A method may store in a register an address of a memory corruption detection (MCD) table. The method receives, from an application, a memory store request to store data in a first portion of a contiguous memory block of a memory and sends, to the application, a fault message when a fault event associated with the first portion occurs in view of a protection mode of the first portion, wherein the protection mode indicates that the first portion is write protected.

Claim (Index 1):
A method comprising:\n storing in a register an address of a memory corruption detection (MCD) table; receiving, from an application, an allocation request for allocation of a memory object with a contiguous memory block in memory; allocating the contiguous memory block for the memory object in view of a size of the memory object requested; writing, into the MCD table, a MCD metadata word, wherein the MCD metadata word comprises:\n a first MCD unique identifier (ID) associated with the contiguous memory block; and \n a write protection indicator that indicates a first protection mode of a first portion of the contiguous memory block; \n receiving, from the application, a memory store request to store data in the first portion of the contiguous memory block of the memory object of the memory, wherein the memory store request comprises a first pointer indicating a first location of the first portion in the memory block to store the data; retrieving, from the MCD table, the write protection indicator that indicates the first protection mode of the first portion; and sending, to the application, a fault message when a fault event associated with the first portion occurs based on the first protection mode of the first portion.
