Name of the Vulnerable Software and Affected Versions Xen versions 4.5.x through 4.7.x

Description The issue allows local 32-bit PV guest OS kernels to cause a denial of service, resulting in a hypervisor and VM crash, by triggering a safety check due to the lack of Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery.

Recommendations For Xen versions 4.5.x through 4.7.x, consider disabling 32-bit PV guest OS kernels until a patch is available to implement SMAP whitelisting and prevent the denial of service.
