Abstract
A technique is provided for detecting vulnerabilities in system code on a computer. Supervisor call routines and program call routines of the system code are analyzed to determine which are available to a caller program that is an unauthorized program and has a PSW key-. Predefined input parameters are provided to test cases for use by the supervisor call routines and the program call routines in order to generate an output for analysis. The output is analyzed to determine when supervisor call routines and/or program call routines performed a potential vulnerability action. The potential vulnerability action include reading from fetch protected storage, writing to system key (key-) storage, and attempting to access unallocated storage while running with a PSW key-
