Docker Layer 2 ICC Bug vs Bitdefender GravityZone Security for Containers: 2026 Comparison

Docker Layer 2 ICC Bug

Teams running multi-tenant Docker environments who need to validate that inter-container isolation actually works should test Docker Layer 2 ICC Bug immediately; it exposes a real bypass in ICC enforcement that raw socket access creates, one that most container security tools and network policies silently miss. The 66 GitHub stars reflect active adoption among practitioners who've caught this in production, and the vulnerability remains unpatched in older Docker versions still in heavy use. Skip this if you're already using eBPF-based runtime monitoring or running only single-tenant clusters where container-to-container trust assumptions hold; this tool does one thing and doesn't prevent the vulnerability, only detects that it exists.
