Name of the Vulnerable Software and Affected Versions Xen versions 4.0, 4.1.x, 4.2.x

Description The issue arises when Xen uses Intel VT-d for PCI passthrough and does not properly configure VT-d for devices behind a legacy PCI Bridge. This allows local guests to cause a denial of service to other guests by injecting an interrupt.

Recommendations For versions 4.0, 4.1.x, and 4.2.x, consider disabling the PCI passthrough feature for devices behind a legacy PCI Bridge until a proper configuration method is available. Restrict access to the VT-d configuration to minimize the risk of exploitation. Avoid using the Intel VT-d for PCI passthrough with devices behind a legacy PCI Bridge in these versions.
