Unauthorized Error Injection Can Degrade Hardware Redundancy

Hardware designers often add duplicate components, like backup processors or memory channels, to maintain system performance and reliability if a primary part fails. This vulnerability undermines that safety net by allowing an unauthorized user or process to inject errors into these backup blocks, corrupting them and making the redundant path unusable. Once the redundancy is compromised, the system is forced to operate in a degraded mode with reduced fault tolerance. This weakened state is often the primary goal of the attack, as it makes the entire system more susceptible to follow-up exploits that could cause complete failure or data corruption.
