proc_pid_mem(5)

💖 proc_pid_mem — memory 💖

okay bestie, welcome to proc_pid_mem(5), straight out of the File Formats Manual section of the man pages. it's a lil one, but it's iconic. let's get into it 🫶

✨ NAME ✨

/proc/pid/mem — memory. that's it. that's the whole name. short, sweet, main character energy 💅

🌸 DESCRIPTION 🌸

🦋 /proc/pid/mem

okay so this file is literally the cheat code to a process's brain 🧠✨. you can use it to access the pages of a process's memory — and you do that through open(2), read(2), and lseek(2).

so like, open(2) it, read(2) from it, lseek(2) around in it. three syscalls, one file, endless possibilities. it's giving "i have the keys to the kingdom" 🔥

⚠️ okay but listen — you do NOT just get to walk in here. permission to access this file is governed by a ptrace access mode PTRACE_MODE_ATTACH_FSCREDS check. yeah. that check. see ptrace(2) for the whole rundown, bestie. no cap, they will vibe check you at the door 💀
