CVE-2025-64436
Last modified
CVE-2025-64436 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. KubeVirt is a virtual machine management add-on for Kubernetes. In 1.5.0 and earlier, the permissions granted to the virt-handler service account, such as the ability to update VMI and patch nodes, could be abused to force a VMI migration to an attacker-controlled node. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
Description
KubeVirt is a virtual machine management add-on for Kubernetes. In 1.5.0 and earlier, the permissions granted to the virt-handler service account, such as the ability to update VMI and patch nodes, could be abused to force a VMI migration to an attacker-controlled node. This vulnerability could otherwise allow an attacker to mark all nodes as unschedulable, potentially forcing the migration or creation of privileged pods onto a compromised node.
