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...

CVE-2019-18424

Xen vulnerability CVE-2019-18424 affects the Xen hypervisor (4.12.x) where, when PCI pass-through is used, deassignment of a PCI device from an untrusted domain can allow in-flight DMA to target host memory, risking host-OS privilege escalation. The issue arises because devices reassigned to dom0...

passed through PCI devices may corrupt host memory after deassignment

ISSUE DESCRIPTION When a PCI device is assigned to an untrusted domain, it is possible for that domain to program the device to DMA to an arbitrary address. The IOMMU is used to protect the host from malicious DMA by making sure that the device addresses can only target memory assigned to the...
