Common attack vectors include: privileged containers (--privileged), incorrectly mounted host directories, insecure cgroup/namespace configuration, Docker socket mounts, kernel exploits, and Runc CVEs. Protection: unprivileged containers, read-only filesystems, Seccomp/AppArmor profiles, no privileged ports below 1024.
