Xen PV Guest Non-SELFSNOOP CPU Memory Corruption Exploit

On CPUs without SELFSNOOP support, a Xen PV domain that has access to a PCI device which grants the domain the ability to set arbitrary cache attributes on all its pages can trick Xen into validating an L2 pagetable that contains a cacheline that is marked as clean in the cache but actually diffe...
