kata-containers: Kata Containers: Denial of Service and filesystem errors due to malformed container image processing
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD, Azure Linux. Niedriger laut Red Hat (mittel).
Beschreibung
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.
