"value": "A flaw was found in QEMU, in the virtio-scsi, virtio-blk, and virtio-crypto devices. The size for virtqueue_push as set in virtio_scsi_complete_req / virtio_blk_req_complete / virito_crypto_req_complete could be larger than the true size of the data which has been sent to guest. Once virtqueue_push() finally calls dma_memory_unmap to ummap the in_iov, it may call the address_space_write function to write back the data. Some uninitialized data may exist in the bounce.buffer, leading to an information leak."

El tama\u00f1o de virtqueue_push, tal como se establece en virtio_scsi_complete_req / virtio_blk_req_complete / virito_crypto_req_complete, podr\u00eda ser mayor que el tama\u00f1o real de los datos que se enviaron al invitado. Una vez que virtqueue_push() finalmente llama a dma_memory_unmap para aplicar un mapa de unum a in_iov, puede llamar a la funci\u00f3n address_space_write para volver a escribir los datos. Es posible que existan algunos datos no inicializados en el bounce.buffer, lo que genera una fuga de informaci\u00f3n."
