Name of the Vulnerable Software and Affected Versions Xen versions 4.8.x through 4.11.x

Description The issue allows x86 PV guest OS users to cause a denial of service due to mishandling of failed IOMMU operations, which causes a bug check during the cleanup of a crashed guest. This is a result of insufficient input validation, enabling an attacker to exploit the issue and cause a denial of service.

Recommendations For Xen versions 4.8.x through 4.11.x, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
