CVE-2025-64433

CVE-2025-64433 affects KubeVirt prior to 1.5.3 and 1.6.1, enabling a VM to read arbitrary files from the virt-launcher pod filesystem via improper symlink handling when mounting PVCs. The issue arises when a malicious user controls PVC contents and can create a symlink to a file in the virt-launc...

CVE-2025-64433 KubeVirt Arbitrary Container File Read

KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.5.3 and 1.6.1, a vulnerability was discovered that allows a VM to read arbitrary files from the virt-launcher pod's file system. This issue stems from improper symlink handling when mounting PVC disks into a VM...

CVE-2025-64437 KubeVirt Isolation Detection Flaw Allows Arbitrary File Permission Changes

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-2025-64437

KubeVirt (virt-handler) vulnerability CVE-2025-64437 affects versions before 1.5.3 and 1.6.1. The issue is that virt-handler does not verify whether the launcher-sock is a symlink or a regular file, allowing an attacker who controls the virt-launcher pod’s filesystem to change ownership of arbitr...

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...

CVE-2025-64436 KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes

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...

CVE-2025-64436

KubeVirt CVE-2025-64436 affects the virt-handler service account in KubeVirt up to version 1.5.0, where overprivileged permissions (e.g., updating VMI, patching nodes) could be abused to migrate a VMI to an attacker-controlled node or mark all nodes as unschedulable, potentially forcing privilege...

CVE-2025-64435 KubeVirt VMI Denial-of-Service (DoS) Using Pod Impersonation

KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.7.0-beta.0, a logic flaw in the virt-controller allows an attacker to disrupt the control over a running VMI by creating a pod with the same labels as the legitimate virt-launcher pod associated with the VMI. This can...

CVE-2025-64435

CVE-2025-64435 affects KubeVirt’s virt-controller. A logic flaw allows an attacker to disrupt control of a running VMI by creating a pod with the same labels as the legitimate virt-launcher pod, causing the virt-controller to bind the fake pod to the VMI, leading to incorrect status updates and a...

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-2025-64434

KubeVirt Vulnerability CVE-2025-64434 affects virt-handler’s peer verification (verifyPeerCert). In affected releases prior to 1.5.3 and 1.6.1, a compromised virt-handler could exploit shared credentials to impersonate virt-api and perform privileged operations against other virt-handler instance...
