ABSTRACT:
Machine-readable media, methods, apparatus and system for detecting a data access violation are described. In some embodiments, current memory access information related to a current memory access to a memory address by a current user thread may be obtained. It may be determined whether a cache includes a cache entry associated with the memory address. If the cache includes the cache entry associated with the memory address, then, an access history stored in the cache entry and the current memory access information may be analyzed to detect if there is at least one of an actual violation and a potential violation of accessing the memory address.
