Consider an MMU that implements the base & bound approach. However, it does not perform the bound check and immediately returns the base + the input virtual memory address.

Consider two single-threaded processes, P1 and P2.
Which of the following statements are true?

 Many may be true.

Answer

P1 may be able to access memory that it is not supposed to.

Answer

P1 may interfere with P2's execution, e.g., if P2 makes a function call, when the function returns, the CPU may not execute the instruction coming after the call.

Answer

P1 may be able to read and/or modify P2's data.

Answer

P1 may change the values that have been pushed into P2's stack, causing P2 to pop the wrong values from the stack.
