Abstract
Generally discussed herein are devices, systems, and methods for software memory tagging that provides buffer overflow protection. A method can include responsive to a memory write operation to write data to a heap of a memory, identifying a first tag value associated with a first address of the memory write operation in the bit map, comparing, for each address after the first address affected by the memory write operation, respective tag values in a bit map of the memory to the identified first tag value, and halting execution of the application if any of the respective tag values do not match the first tag value.
