Some of this sounds like the "magic svcs" that I've seen people use for 
"testing".

  -    Some code that is executing in an authorized state
         - Supervisor state
         - PSW key 0-7
         - Ability to issue MODESET SVC (APF authorized)

-    This code would have one of the following flaws:
         - Store into requester provided storage address while in an authorized 
state (usually means running in a system psw key (0-7))
         - Branch to a requester provided storage address
         - Returning control to the requester in an authorized state

SVCs, PC routines, and system exits all would have this potential.
