    4 vulnerabilities found for Red Hat Container Native Virtualization 4.19 by Red Hat

    CVE-2026-9804 (GCVE-0-2026-9804)

    Vulnerability from nvd – Published: 2026-05-28 08:15 – Updated: 2026-06-22 19:24

    Title
    Kubevirt: kubevirt: vmexport directory symlink escape enables exporter pod file read
    Summary
    A flaw was found in KubeVirt's virt-exportserver component. An attacker with specific namespace-level access can exploit a path traversal vulnerability in the VMExport directory endpoint. By placing a symbolic link (symlink) within an exported filesystem Persistent Volume Claim (PVC) that points outside its designated mount root, the attacker can read arbitrary files from the exporter pod's filesystem. This leads to information disclosure, potentially exposing sensitive data.

    CVE-2026-7374 (GCVE-0-2026-7374)

    Vulnerability from nvd – Published: 2026-05-26 13:14 – Updated: 2026-06-15 18:55

    Title
    Kubevirt: kubevirt virt-handler: privilege escalation and node compromise via symlink following vulnerability
    Summary
    A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.

    CVE-2026-9804 (GCVE-0-2026-9804)

    Vulnerability from cvelistv5 – Published: 2026-05-28 08:15 – Updated: 2026-06-22 19:24
    VLAI
    Title
    Kubevirt: kubevirt: vmexport directory symlink escape enables exporter pod file read
    Summary
    A flaw was found in KubeVirt's virt-exportserver component. An attacker with specific namespace-level access can exploit a path traversal vulnerability in the VMExport directory endpoint. By placing a symbolic link (symlink) within an exported filesystem Persistent Volume Claim (PVC) that points outside its designated mount root, the attacker can read arbitrary files from the exporter pod's filesystem. This leads to information disclosure, potentially exposing sensitive data.

    CVE-2026-7374 (GCVE-0-2026-7374)

    Vulnerability from cvelistv5 – Published: 2026-05-26 13:14 – Updated: 2026-06-15 18:55
    VLAI
    Title
    Kubevirt: kubevirt virt-handler: privilege escalation and node compromise via symlink following vulnerability
    Summary
    A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.

This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host\u0027s container runtime (CRI-O) socket, an attacker can hijack virt-handler\u0027s privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster."
