Medium (6.3) in katacontainers runtime. EPSS 1.1% chance of exploitation in the next 30 days. Fixed in github.com/kata-containers/agent 1.10.5, 1.11.1, 1.9.1.
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.
