Name of the Vulnerable Software and Affected Versions Xen versions 4.0 through 4.1

Description The issue allows local guest OS users to cause a denial of service (host hang) via sequential execution of instructions across a non-canonical boundary on "older" AMD CPUs when running a 64-bit PV guest.

Recommendations For Xen versions 4.0 through 4.1, consider restricting the use of 64-bit PV guests on "older" AMD CPUs to minimize the risk of exploitation.
