Contrast is a confidential-computing runtime for Kubernetes that, before version 1.18.0, contains a vulnerability in the guest kernel's ACPI/AML handling. This vulnerability allows an attacker controlling the host to inject malicious AML bytecode, leading to arbitrary code execution and disclosure or modification of confidential guest data. The issue affects AMD SEV-SNP platforms Metal-QEMU-SNP and Metal-QEMU-SNP-GPU but not Metal-QEMU-TDX. Version 1.18.0 mitigates the attack by sandboxing the AML interpreter to prevent unauthorized memory access. This vulnerability is generic to confidential computing setups exposing the ACPI interface to the host.
