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 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...

CVE-2025-64436: Improper Privilege Management

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-2025-64432: Improper Authentication

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...

CVE-2025-64433: Improper Limitation of a Pathname to a Restricted Directory

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-2025-64434: Improper Authentication

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: Improper Link Resolution Before File Access

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 ...

GHSA-2R4R-5X78-MVQF 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...
