This offset\ncalculation is what triggers the stack-out-of-bounds error.\n\nIn order to fix this, pass in a bprm_is_check boolean which can be set\ndepending on how process_measurement is called. If the caller has a\nlinux_binprm pointer and the function is BPRM_CHECK we can determine\nis_check and set it then. Otherwise set it to false.",
