Demonstrative Examples
Example 1:
Suppose a processor's Memory Management Unit (MMU) has 5 other shadow MMUs to distribute
its workload for its various cores. Each MMU has the start address and end address of "accessible"
memory. Any time this accessible range changes (as per the processor's boot status), the main
MMU sends an update message to all the shadow MMUs.
Suppose the interconnect fabric does not prioritize such "update" packets over other general traffic
packets. This introduces a race condition. If an attacker can flood the target with enough messages
so that some of those attack packets reach the target before the new access ranges gets updated,
then the attacker can leverage this scenario.
