## What it is
A C-based root privilege escalation exploit for CVE-2022-0847 (Dirty Pipe), a Linux kernel vulnerability. It modifies Max Kellermann's proof of concept to overwrite root's password field in /etc/passwd, pop a root shell, and then restore the file.

## Use cases
- exploit dirty pipe vulnerability on vulnerable linux kernels
- gain root shell via CVE-2022-0847
- test whether a linux system is patched against dirty pipe
- privilege escalation demonstration in penetration testing
- learn how the dirty pipe kernel bug works

## When to choose
- you need a quick, ready-to-run exploit for CVE-2022-0847 on a vulnerable Linux host
- you are doing authorized penetration testing or security research on dirty pipe
- you want a minimal C exploit that restores /etc/passwd after use

## When to avoid
- the target kernel is patched against CVE-2022-0847 (fixed in 5.16.11, 5.15.25, 5.10.102)
- you need a general-purpose privilege escalation toolkit rather than a single-CVE exploit
- unauthorized use - exploiting systems you do not own or have permission to test is illegal
