Descriptions

The make_response function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS (or other guest OS) kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structures, aka XSA-216.

La función make_response en el archivo drivers/block/xen-blkback/blkback.c en el kernel de Linux anterior a versión 4.11.8, permite a los usuarios del sistema operativo invitado obtener información confidencial de la memoria del kernel del sistema operativo host (u otro sistema operativo invitado) mediante el aprovechamiento de la copia de campos de relleno no inicializados en estructuras de respuesta de la interfaz del bloque Xen, también se conoce como XSA-216.
