Abstract
An apparatus has a data memory region with multiple data symbols and inaccessible zones, a first inaccessible zone placed before each data symbol and a second inaccessible zone placed after each data symbol. The apparatus also has a shadow memory region corresponding to the data memory region. The shadow memory region includes multiple data elements. Each data element corresponds to one of the data symbols or inaccessible zones and indicates an accessibility state of the corresponding data symbol or inaccessible zone. The apparatus includes an address sanitizer hardware block within a processing core and coupled to the shadow memory region. The address sanitizer hardware block checks a selected data element of the shadow memory region, corresponding to a selected data symbol or inaccessible zone being accessed, to determine the accessibility state of the selected data symbol or inaccessible zone, prior to accessing the selected data symbol or inaccessible zone.
