A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially escalating their privileges within the guest. A malicious local user in the host might also leverage this unexpected executable file created by the guest to escalate their privileges on the host system."

Este fallo está estrictamente relacionado con CVE-2018-13405. Un usuario invitado local puede crear archivos en los directorios compartidos por virtio-fs con propiedad de grupo no intencionada en un escenario en el que un directorio es SGID a un determinado grupo y es escribible por un usuario que no es miembro del grupo. Esto podría permitir a un usuario malicioso no privilegiado dentro del huésped conseguir acceso a recursos accesibles al grupo root, escalando potencialmente sus privilegios dentro del huésped. Un usuario local malicioso en el huésped también podría aprovechar este archivo ejecutable no esperado creado por el huésped para escalar sus privilegios en el sistema huésped"
