This means that if we free the known-address chunk and replace it with a VirtIOSoundPCMBuffer - which is straightforward, since we control the buffer allocation size through the in_sg iovec - we can use the arbitrary read primitive to read its .vq pointer, then follow that pointer to leak .handle_output from the VirtQueue structure. In our case, that field points to virtio_snd_handle_rx_xfer, which gives us QEMU's base address.
