Xen DoS using IOMMU faults from PCI-passthrough guest

ISSUE DESCRIPTION A VM that controls a PCIE device directly can cause it to issue DMA requests to invalid addresses. Although these requests are denied by the IOMMU, the hypervisor needs to handle the interrupt and clear the error from the IOMMU, and this can be used to live-lock a CPU and...

VT-d (PCI passthrough) MSI trap injection

ISSUE DESCRIPTION Intel VT-d chipsets without interrupt remapping do not prevent a guest which owns a PCI device from using DMA to generate MSI interrupts by writing to the interrupt injection registers. This can be exploited to inject traps and gain control of the host. VULNERABLE SYSTEMS You ar...
