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

Vulnerability from nvd – Published: 2026-05-26 13:14 – Updated: 2026-05-28 02:39

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

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.
