CVE-2026-24054
Description
A flaw was found in Kata Containers. When a container image is malformed or lacks layers, the system incorrectly processes the container's root filesystem as a block device. This misidentification can lead to the host's underlying storage device being hotplugged into the virtual machine, causing filesystem errors on the host, including potential data corruption due to double inode allocation, and may result in the host's block device becoming read-only. This vulnerability can lead to a Denial of Service (DoS) on the host system.
Statement
This vulnerability is rated as Moderate impact for Red Hat OpenShift Container Platform because exploitation requires privileges to schedule workloads using the Kata Containers runtime. Within OpenShift sandboxed containers environments, launching a pod with an empty or malformed image root filesystem can improperly attach host storage to the guest VM, triggering node-level filesystem inconsistencies and service disruption. Because cluster role-based access control restricts who can define and execute sandboxed workloads, unauthenticated or unauthorized remote actors cannot trigger this condition directly.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
