Improper Privilege Management

kubevirt.io/kubevirt is vulnerable to improper privilege management. The vulnerability is due to excessive permissions granted to the virt-handler service account, which allows an attacker to abuse update and patch capabilities to force VMI migration or schedule privileged pods onto a compromised...

Improper Certificate Validation

kubevirt.io/kubevirt is vulnerable to improper certificate validation. The vulnerability is due to flawed peer verification logic in virt-handler, which allows an attacker to exploit shared credentials from a compromised instance to impersonate virt-api and execute privileged operations on other...

CVE-2025-64434

KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.5.3 and 1.6.1, due to the peer verification logic in virt-handler via verifyPeerCert, an attacker who compromises a virt-handler instance, could exploit these shared credentials to impersonate virt-api and execute privileg...

CVE-2025-64437

KubeVirt is a virtual machine management add-on for Kubernetes. In versions before 1.5.3 and 1.6.1, the virt-handler does not verify whether the launcher-sock is a symlink or a regular file. This oversight can be exploited, for example, to change the ownership of arbitrary files on the host node ...

CVE-2025-64436

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...
