CVE-2026-24054
CWE-754Published: January 29, 2026· Updated: Jun 17, 2026
Official Description
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.
Risk Analysis
Kata Containers versions prior to 3.26.0 contain a flaw where malformed container images can cause the host's block device to be mounted incorrectly. This can lead to filesystem errors and unauthorized access to host resources.
No public exploit is known, and it is not in KEV. The vulnerability is remotely exploitable with low complexity.
Upgrade Kata Containers to version 3.26.0 or later.
Technical Analysis
CVE-2026-24054 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
