Linux Container Escape PoCs for CVE-2026-52910 & CVE-2026-80521

Summary

A target-specific proof-of-concept exploit toolkit and disposable QEMU VM testing harness for two destructive Linux kernel vulnerabilities leading to container escape: CVE-2026-52910 (reuseport classic BPF) and CVE-2026-80521 (AF_UNIX garbage collection). It includes automated golden VM image builders for Ubuntu 24.04 and 26.04 to safely evaluate container isolation boundaries.

Why it matters

Demonstrates that container isolation can be completely compromised via Linux kernel subsystem flaws, providing security researchers with reproducible testbeds to evaluate kernel-level container escape threats.
