SUSE 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...

SUSE CVE-2019-19579

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 and assignable-add is not used, because of an incomplete fix for CVE-2019-18424. XSA-302 relies on the use of libxl's...

SUSE CVE-2021-27379

An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unintended read/write DMA access, and possibly cause a denial of service host OS crash or gain privileges. This occurs because a backport missed a flush, and thus IOMMU updates were not always correct...
