DISPUTED In drivers/char/virtio_console.c in the Linux kernel before
5.13.4, data corruption or loss can be triggered by an untrusted device
that supplies a buf->len value exceeding the buffer size. NOTE: the vendor
indicates that the cited data corruption is not a vulnerability in any
existing use case; the length validation was added solely for robustness in
the face of anomalous host OS behavior.
