CVE-2025-64434 KubeVirt Improper TLS Certificate Management Handling Allows API Identity Spoofing

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...

Incorrect Permission Assignment for Critical Resource

Overview Affected versions of this package are vulnerable to Incorrect Permission Assignment for Critical Resource due to the virt-api component failing to validate the CN field in client TLS certificates against allowed values in the extension-apiserver-authentication configmap. An attacker can...

GHSA-46XP-26XH-HPQH KubeVirt Vulnerable to Arbitrary Host File Read and Write

Summary The hostDisk feature in KubeVirt allows mounting a host file or directory owned by the user with UID 107 into a VM. However, the implementation of this feature and more specifically the DiskOrCreate option which creates a file if it doesn't exist, has a logic bug that allows an attacker t...

CVE-2025-64432 KubeVirt Affected by an Authentication Bypass in Kubernetes Aggregation Layer

KubeVirt is a virtual machine management add-on for Kubernetes. Versions 1.5.3 and below, and 1.6.0 contained a flawed implementation of the Kubernetes aggregation layer's authentication flow which could enable bypass of RBAC controls. It was discovered that the virt-api component fails to...

Kubevirt 后置链接漏洞

Kubevirt is an open source virtual machine manager for KubeVirt. A back-linking vulnerability exists in KubeVirt versions prior to 1.5.3 and prior to 1.6.1, which stems from virt-handler not verifying that the launcher-sock is a symbolic link or a regular file, which could result in the ownership...

Kubevirt 路径遍历漏洞

Kubevirt is a virtual machine manager in the KubeVirt open source. A path traversal vulnerability exists in KubeVirt versions prior to 1.5.3 and prior to 1.6.1, which stems from mishandling of symbolic links and a file ownership change issue, and could lead to reading arbitrary files in the...

Kubevirt 安全漏洞

Kubevirt is an open source virtual machine manager from KubeVirt. A security vulnerability exists in Kubevirt 1.5.0 and earlier versions, which stems from overprivileged virt-handler service account privileges, which could result in forced migration of VM instances to an attacker-controlled node ...

Kubevirt 安全漏洞

Kubevirt is an open source virtual machine manager from KubeVirt. A security vulnerability exists in Kubevirt versions prior to 1.7.0-beta.0, which stems from a logic flaw in the virt-controller that could lead to a denial-of-service attack...

KubeVirt Isolation Detection Flaw Allows Arbitrary File Permission Changes

Summary Short summary of the problem. Make the impact and severity as clear as possible. It is possible to trick the virt-handler component into changing the ownership of arbitrary files on the host node to the unprivileged user with UID 107 due to mishandling of symlinks when determining the roo...

GHSA-7XGM-5PRM-V5GC KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes

Summary 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. Details Following the GitHub security advisory published on March 23 2023, a ValidatingAdmissionPolicy w...
