Abusing Processor Exception for General Binary Instrumentation on Bare-metal Embedded Devices

arXiv:2311.16532v2 Announce Type: replace
Abstract: Analyzing the security of closed-source drivers and libraries in embedded systems holds significant importance, given their fundamental role in the supply chain. Unlike x86, embedded platforms lack comprehensive binary manipulating tools, making it difficult for researchers and developers to effectively detect and patch security issues in such closed-source components. Existing works either depend on full-fledged operating system features or suffer from tedious corner cases, restricting their application to bare-metal firmware prevalent in embedded environments. In …
