Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. Prior to version 4.0.0, kata-runtime is vulnerable to host code execution via an unvalidated configuration path annotation. The runtime accepts an arbitrary io.katacontainers.config_path pod annotation and loads the referenced host TOML file without restriction. As a result, a pod user who can place a file at a host-visible path can supply a configuration that selects an attacker-controlled hypervisor or virtio-fs daemon binary, executing code as root on the host. This issue is fixed in version 4.0.0.

Affected: openEuler:24.03-LTS-SP4: kata-containers, openEuler:20.03-LTS-SP4: kata-containers, openEuler:22.03-LTS-SP4: kata-containers, openEuler:24.03-LTS-SP1: kata-containers, openEuler:24.03-LTS-SP3: kata-containers

This is core component of Kata Container, to make it work, you need a isulad/docker engine. Security Fix(es):
