AI Summary

Toolkit with a non-destructive detector and proof-of-concept for escalating user privileges on vulnerable Linux systems affected by CVE-2026-31431.

How It Works

1
🔍 Discover the toolkit

You learn about a potential security flaw in Linux systems from a research blog and find this helpful testing toolkit.

2
📥 Get the testing tools

You download the safe checker and escalator tools to the Linux computer you own or are authorized to test.

3
🧪 Run the safe checker

You start the checker, which creates its own temporary test file to quietly probe for the hidden weakness.

4
🚨 Weakness detected

The checker confirms the flaw exists by spotting a special marker it placed, meaning your system could let regular users gain extra powers.

5
🔧 Set up the power boost

The escalator tool scans your user details in the system list and prepares to swap your access code to the top level in memory.

6
🔓 Boost to full access

You trigger the boost, which updates the memory view of your user info, then switch to super user mode by entering your own password.

7
🧹 Clean up afterward

You clear the temporary memory change using a simple command or reboot to return everything to normal.

✅ Test finished safely

You've verified the issue, gained insight into the risk, and know exactly how to protect your system by applying fixes.

What is cve_2026_31431?

This Python repo delivers a detector and proof-of-concept exploit (POC meaning a working demo) for CVE-2026-31431, a Linux kernel bug in the algif_aead AF_ALG socket that enables local privilege escalation via page-cache corruption. Run the detector script to safely check vulnerability on kernels like Ubuntu 24.04 or RHEL without touching system files—it exits with codes signaling patched, vulnerable, or error states. The exploit script patches your user's UID to 0 in /etc/passwd's page cache, then chains into su for a root shell using your real password, all in pure stdlib Python 3.10+.

Why is it gaining traction?

Unlike messy eternalblue exploit GitHub repos or web app POCs like crushftp exploit GitHub and nextcloud exploit GitHub, this stands out with a non-destructive detector that confirms the primitive before escalation—ideal for authorized testing without risk. Its reversible changes (evict cache post-exploit) and detailed mitigation steps (disable algif_aead module) make it practical, beating half-baked pocketbase exploits or exploit GitHub as infinite storage gimmicks. At 88 stars, it hooks security devs verifying 2026-era kernel patches.

Who should use this?

Kernel security researchers auditing distros like Amazon Linux 2023 or SUSE. Red teamers on authorized pentests needing reliable LPE on affected systems. Distro maintainers confirming fixes before deployment.

Verdict

Grab it for legit vuln hunting—excellent docs and detector make it mature despite 88 stars and 1.0% credibility score; low score flags niche risks, but tests cover edge cases well. Skip for prod or unauthorized use; pair with the disclosure writeup.
