The record

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 to read and write arbitrary files owned by more privileged users on the host system.
