CVE-2019-18424

A flaw was found in Xen. A PCI device assigned to an untrusted domain can be programmed to an arbitrary address in DMA. When the guest domain is removed, the device is assigned back to dom0 allowing any in-flight DMA to potentially target critical host data. The highest threat from this...

CVE-2019-18424

An issue was discovered in Xen through 4.12.x allowing attackers to gain host OS privileges via DMA in a situation where an untrusted domain has access to a physical device. This occurs because passed through PCI devices may corrupt host memory after deassignment. When a PCI device is assigned to...
