Vulnerability from osv_openeuler – Published: 2026-02-28 11:10 – Updated: 2026-08-06 11:10 – Source website

Summary

kata-containers security update

Details

This is core component of Kata Container, to make it work, you need a isulad/docker engine.

Security Fix(es):

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-2026-24054)

Severity

8.8 (High)
