Xen Missed Flush DoS or Privilege Escalation (XSA-366)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by an issue 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...

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...

Denial Of Service (DoS)

Xen is vulnerable to denial of service DoS. It is allowing x86 Intel HVM guest OS users to cause a host OS denial of service or possibly gain privileges because of insufficient cache write-back under VT-d. When page tables are shared between IOMMU and CPU, changes to them require flushing of both...

Xen Insufficient Cache Write-Back (XSA-321)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a denial of service and potential privilege escalation due to an insufficient cache write-back under VT-d. A malicious guest may be able to retain read/write DMA access to frames returned...

An issue was discovered in Xen through 4.13.x, allowing x86 Intel HVM guest OS users to cause a host OS denial of service or possibly gain privileges because of insufficient cache write-back under VT-d. When page tables are shared between IOMMU and CPU, changes to them require flushing of both...

CVE-2020-15565

Root cause: CVE-2020-15565 arises from insufficient cache write-back under VT-d when page tables are shared between IOMMU and CPU, requiring flushing of both CPU and IOMMU TLBs. A backport/backing fixes missed a necessary cache flush, leaving IOMMU updates potentially non-coherent. Affected produ...

insufficient cache write-back under VT-d

ISSUE DESCRIPTION When page tables are shared between IOMMU and CPU, changes to them require flushing of both TLBs. Furthermore, IOMMUs may be non-coherent, and hence prior to flushing IOMMU TLBs CPU cached also needs writing back to memory after changes were made. Such writing back of cached dat...
