Safe read-only check script for Copy Fail / CVE-2026-31431

Safe read-only check script for Copy Fail / CVE-2026-31431

Hi,

I created a small Bash script to help Linux admins safely check systems for the known algif_aead-based Copy Fail / CVE-2026-31431 attack path.

The goal is to provide a defensive check without running exploit code.

What it does:

  • checks whether algif_aead is currently loaded
  • checks whether algif_aead can be loaded via modprobe dry-run
  • checks for modprobe block rules
  • checks Debian/Ubuntu kernel/kmod update status
  • checks whether a reboot is required
  • prints a clear final result for non-specialists

What it does not do:

  • does not run exploit code
  • does not modify the system
  • does not download additional payloads
  • does not attempt privilege escalation

I mainly built this because I did not want to run public PoC exploit code on production systems just to check exposure.

Feedback, improvements, and distro-specific suggestions are welcome.

Looking for feedback on a small Windows Robocopy GUI I built

Hi everyone,

I hope this is okay to post here. I’m not selling anything — I built a small free Windows tool and would appreciate feedback from people who regularly copy, sync or compare larger folders.

Required info:

  • OS: Windows
  • Use case: personal and business use
  • Data size: from a few GB up to multiple TB, depending on the backup / sync job

The tool is a GUI for Robocopy called RoboSync Manager. The idea is to make Robocopy a bit easier to use without hiding what it actually does.

It includes source/destination selection, compare mode, live output, command preview and HTML reports. It also supports local folders and network shares.

GitHub:

I would really appreciate honest feedback, especially from people who already use Robocopy, FreeFileSync, SyncBack, TeraCopy or similar tools.

Would this be useful, or is there something important missing?
