| Thread-topic: | information leaking between domains via granted pages? |
Is there a statement anywhere regarding information that could be leaked or modified between domains when pages are granted? Eg, Dom0 sends a network packet to DomU. The network data only uses 64 bytes in the page, but DomU (via a specially crafted netfront driver) can access and record all the other data in the page...
