Title
Kata Containers Runtime: Host block device can be hotplugged to the VM if the container image is malformed or contains no layers
Summary
Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. In versions prior to 3.26.0, when a container image is malformed or contains no layers, containerd falls back to bind-mounting an empty snapshotter directory for the container rootfs. When the Kata runtime attempts to mount the container rootfs, the bind mount causes the rootfs to be detected as a block device, leading to the underlying device being hotplugged to the guest. This can cause filesystem-level errors on the host due to double inode allocation, and may lead to the host's block device being mounted as read-only. Version 3.26.0 contains a patch for the issue.

CVE-2025-58354 (GCVE-0-2025-58354)

Title
Kata Containers coco-tdx malicious host can circumvent initdata verification
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.
