race in VT-d domain ID cleanup

ISSUE DESCRIPTION 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 housekeeping...

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...

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-2022-26359

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...

Xen IOMMU page mapping issues on x86 (XSA-378)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by multiple vulnerabilities in IOMMU page mapping on x86. Both AMD and Intel allow ACPI tables to specify regions of memory which should be left untranslated, which typically means these...
