CVE-2022-26357
race in VT-d domain ID cleanup Xen domain IDs are up to 15 bits wide. VT-d hardware may allow for only less than 15 bits to hold a domain ID associating a physical device with a particular domain. Therefore internally Xen domain IDs are mapped to the smaller value range. The cleaning up of the...

IOMMU: RMRR (VT-d) and unity map (AMD-Vi) handling issues
ISSUE DESCRIPTION Certain PCI devices in a system might be assigned Reserved Memory Regions specified via Reserved Memory Region Reporting, "RMRR" for Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used for platform tasks such as legacy USB emulation. Since the precise purpose...

CVE-2022-26360
CVE-2022-26360 affects Xen with IOMMU: RMRR (VT-d) and Unity Mapping (AMD-Vi). The issue arises when mappings for Reserved Memory Regions or Unity Mapping ranges remain accessible after a device activation, allowing subsequent DMA/interrupts to cause IOMMU faults or memory corruption. The connect...
CVE-2022-26358
CVE-2022-26358 affects the Xen hypervisor (IOMMU: RMRR VT-d and Unity Mapping for AMD-Vi). Issues arise when a device with Reserved Memory Regions remains accessible, potentially causing DMA/interrupts to trigger IOMMU faults or memory corruption. Connected advisories document multiple vendors (S...
CVE-2022-26359
CVE-2022-26359 is a Xen hypervisor issue related to IOMMU handling of RMRR (VT-d) and Unity Mapping (AMD-Vi). Public sources describe that when a device with such a region is active, mappings must remain accessible, and violations can lead to unpredictable DMA/interrupt behavior and memory corrup...
CVE-2022-26361
CVE-2022-26361 affects the Xen hypervisor via IOMMU handling (RMRR VT-d and Unity Mapping AMD-Vi). The issue arises when mappings for Reserved Memory Regions or Unity Mapping ranges must remain accessible and are violated, enabling unpredictable DMA/interrupt behavior and potential memory corrupt...
