Name of the Vulnerable Software and Affected Versions Xen versions 3.3.x through 4.4.x

Description The issue allows local 32-bit HVM guests to cause a denial of service (host crash) via vectors involving altering the high halves of registers while in 64-bit mode, when running on a 64-bit hypervisor.

Recommendations For Xen versions 3.3.x through 4.4.x, consider restricting access to compatibility mode hypercall argument translation to minimize the risk of exploitation until a patch is available.
