Original source text (not a translation)
A flaw was found in Kata Containers. In configurations utilizing genpolicy for Confidential Containers guest protection, a malicious host operator can exploit insufficient validation of CreateContainer mount and storage rules. This allows them to mount arbitrary container-rootfs paths over sensitive host locations or provision arbitrary content, potentially exposing confidential information or enabling the acceptance of attacker-controlled input.
