CVE-2025-64324
Full vulnerability record from the local CVENow database.
Description
KubeVirt is a virtual machine management add-on for Kubernetes. The `hostDisk` feature in KubeVirt allows mounting a host file or directory owned by the user with UID 107 into a VM. However, prior to version 1.6.1 and 1.7.0, 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 to read and write arbitrary files owned by more privileged users on the host system. Versions 1.6.1 and 1.7.0 fix the issue.

"value": "KubeVirt es un complemento de gestión de máquinas virtuales para Kubernetes. La característica 'hostDisk' en KubeVirt permite montar un archivo o directorio del host propiedad del usuario con UID 107 en una máquina virtual. Sin embargo, versiones anteriores a la 1.6.1 y 1.7.0, la implementación de esta característica y más específicamente la opción 'DiskOrCreate' (que crea un archivo si no existe) tiene un error de lógica que permite a un atacante leer y escribir archivos arbitrarios propiedad de usuarios más privilegiados en el sistema host. Las versiones 1.6.1 y 1.7.0 corrigen el problema."
