Hi,

The following vulnerability was published for qemu.

CVE-2024-8612[0]:
| 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.


If you fix the vulnerability please also make sure to include the
