Name of the Vulnerable Software and Affected Versions Xen versions 3.3 through 4.3

Description The issue allows local HVM guests with access to memory mapped I/O regions to cause a denial of service. This can result in CPU consumption and possibly hypervisor or guest kernel panic via a crafted GFN range. The vmx set uc mode function is involved when disabling caches.

Recommendations For Xen versions 3.3 through 4.3, consider disabling the vmx set uc mode function as a temporary workaround until a patch is available. Restrict access to memory mapped I/O regions to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
