Kata Containers doesn't restrict containers from accessing the guest's root filesystem device. Malicious containers can exploit this to gain code execution on the guest and masquerade as the kata-agent. This issue affects Kata Containers 1.11 versions earlier than 1.11.1; Kata Containers 1.10 versions earlier than 1.10.5; and Kata Containers 1.9 and earlier versions.
