Consider a variant of the round robin (RR) scheduling algorithm in which the entries in the ready queue are pointers to the Process Control Blocks (PCBs), rather than the PCBs. A malicious user wants to take advantage and somehow, through a security loophole in the system, manages to put two pointers to the PCB of his/her process with the intention that it can run twice as much. Explain what serious consequence(s) it could have if the (malicious) intention goes undetected by the OS.
