CVE-2026-7374Kubevirt: kubevirt virt-handler: privilege escalation and node compromise via symlink following vulnerability

kubevirt; Red Hat Red Hat Container Native Virtualization 4.12; Red Hat Red Hat Container Native Virtualization 4.13; Red Hat Red Hat Container Native Virtuali… Yayım: (5 ay önce)

Açıklama

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.

Zayıflık türü (CWE): CWE-59

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.
