Summary

Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. In Kata Containers versions from 3.20.0 and before, a malicious host can circumvent initdata verification. On TDX systems running confidential guests, a malicious host can selectively fail IO operations to skip initdata verification. This allows an attacker to launch arbitrary workloads while being able to attest successfully to Trustee impersonating any benign workload. This issue has been patched in Kata Containers version 3.21.0.
