“…Vendors deliver higher-capacity, more capable SSDs, which can serve millions of I/O requests per second [9,55,56]. Flash memories lack support for in-place writes and perform accesses in large units due to physical limitations of flash cell technology.…”

Peripheral devices like SSDs are growing more complex, to the point they are effectively small computers themselves. Our position is that this trend creates a new kind of attack vector, where untrusted software could use peripherals strictly as intended to accomplish unintended goals. To exemplify, we set out to rowhammer the DRAM component of a simplified SSD firmware, issuing regular I/O requests that manage to flip bits in a way that triggers sensitive information leakage. We conclude that such attacks might soon be feasible, and we argue that systems need principled approaches for securing peripherals against them.
