kernelstub/exptemp

ExpTemp is a starter template in the C programming language, aimed at people who do low-level exploit development and reverse engineering. The name suggests Exploit Template. The README is short and lists the building blocks it provides, then tells you to copy the project into a research workspace, edit the main file, and keep reusable logic inside the helper modules. The layout is modular: there are reusable header files and source files that you can include in your own work without rewriting them. The discovery helpers cover system information, process data, the memory map, environment variables, the auxiliary vector (a small block of values the kernel passes to a process at startup), and file descriptors. These are the kind of values a researcher reads early on to figure out what a running program looks like from the inside. For working with another running process, the template ships helpers for authorized PID attach (asking the kernel to let you inspect a process by its ID), reading and inspecting CPU registers, reading memory, writing memory, and dumping memory regions out to a file. Byte-level helpers cover entropy measurement, pattern search, ASCII detection, and basic file input and output. The build setup offers three modes: a normal build for regular use, a debug build, and a sanitizer build. The sanitizer mode lets the compiler add extra runtime checks for things like memory errors, which is useful while developing exploit code that pokes at low-level memory in ways that can crash easily. The README itself is brief and does not describe a specific exploit or target. It positions the project as a scaffold rather than a finished tool, leaving the actual research code for the user to write inside the modules it provides.
