Abstract
A system includes a memory system and a processing system operably coupled to the memory system. The memory system includes a plurality of address spaces. The processing system is configured to perform operations including creating a data space from within a primary address space and a primary address space number access list entry referencing the data space. An unauthorized caller routine in a home address space configured to issue a service request including an address space-switching program call from the home address space to a program call target routine in the primary address space. The address space-switching program call references the primary address space number access list entry in the primary address space. A vulnerability identifier associated with the program call target routine is created and logged based on one or more conditions indicative of a cross-memory integrity violation detected responsive to the service request.
