What is CVE-2026-31431-Copy-Fail---Vulnerability-Detection-Script?

This Shell and Python script scans Linux systems for vulnerability to CVE-2026-31431, a kernel logic flaw letting unprivileged users grab root via page cache corruption in the crypto subsystem. Run it as a non-root user for a color-coded report covering kernel version, patch status, module configs, AF_ALG sockets, setuid binaries, and mitigations like modprobe blacklists—detection only, no exploits. It outputs summaries, JSON for SIEM, or quiet mode with exit codes (0=safe, 1=vulnerable) perfect for automation.

Why is it gaining traction?

Unlike generic kernel checkers, it runs 13 precise tests (10 in Shell) tailored to this CVE, spotting built-in vs module configs that block blacklists, plus container warnings since hosts share kernels. Pipeline-friendly flags like --json and --quiet hook into GitHub Actions or Ansible, failing deploys on vulns—think modsecurity detection only or crowdstrike detection only, but for github detection rules on kernel privesc. No deps beyond Python 3.6+, stdlib-only keeps it lightweight.

Who should use this?

Sysadmins auditing Ubuntu/RHEL/SUSE fleets for the 4.10-6.14 kernel range. DevSecOps engineers gating CI/CD on host scans before container deploys. Security teams building github detection lab playbooks, especially with unpatched systems or IPsec setups.

Verdict

Grab this for fast, actionable CVE-2026-31431 checks—docs and integration shine despite 17 stars and 1.0% credibility score hinting at early maturity. Patch your kernels first, then automate with it.
