## What it is
Dirty Frag is a proof-of-concept Linux kernel local privilege escalation exploit written in C. It chains the xfrm-ESP (CVE-2026-43284) and RxRPC (CVE-2026-43500) page-cache write vulnerabilities to gain root privileges deterministically without race conditions.

## Use cases
- escalate privileges to root on vulnerable Linux kernels
- test whether a Linux system is affected by CVE-2026-43284 or CVE-2026-43500
- study page-cache write kernel exploit techniques
- demonstrate a Dirty Pipe-style logic bug exploit
- verify kernel patches against page-cache write vulnerabilities

## When to choose
- you need to test a Linux system for the Dirty Frag vulnerabilities
- you are researching kernel page-cache write exploit classes
- you need a deterministic LPE PoC that does not rely on race conditions

## When to avoid
- you want a general-purpose security scanning tool
- your kernels are patched against both CVEs
- you are not authorized to test the target system

## Facets
- artifact type: cli-tool
- maturity: active
- function: security, penetration-testing, vulnerability-scanning
- domain: security, operating-systems, developer-tools
- platform: cli
