💻 AI Helped Fix a Critical Bug in a Legacy Router
A developer used AI as an assistant to create a binary patch just 8 bytes in size to fix a critical bug in the legacy dhcrelay3 daemon for EdgeOS routers. The bug caused an RFC 2131 violation and a cascading duplication of DHCP packets. Since the source code was unavailable, the patch was applied directly to the MIPS binary file.
🌍 This demonstrates a new approach to supporting "abandonware" and legacy hardware using AI, which accelerates the reverse engineering process and allows for fixing critical vulnerabilities without access to the original source code.
👤 This serves as an example of how AI can be an effective tool for highly specialized technical tasks, acting not as an autonomous engineer, but as a super-fast mechanical assistant for analyzing assembly code and verifying instructions.
