This is one of the most consequential misunderstandings in modern infrastructure security. Where a virtual machine has a full hypervisor isolation layer separating guest and host kernels, a container shares the host kernel directly. The isolation that makes containers lightweight — Linux namespaces and cgroups — is also what makes them escapable when misconfigured or when vulnerabilities are present.</p> <p>This post examines how container isolation works at the kernel level, walks through the primary escape vectors with working demonstrations, covers real CVEs that enabled escapes, and provides a concrete detection and hardening framework.</p>
