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...
