drivers/char/virtio_console.c in the Linux kernel 4.9.x and 4.10.x before
4.10.12 interacts incorrectly with the CONFIG_VMAP_STACK option, which
allows local users to cause a denial of service (system crash or memory
corruption) or possibly have unspecified other impact by leveraging use of
more than one virtual page for a DMA scatterlist.
