The do_physdev_op function in Xen 4.1.5, 4.1.6.1, 4.2.2 through 4.2.3, and 4.3.x does not properly restrict access to the (1) PHYSDEVOP_prepare_msix and (2) PHYSDEVOP_release_msix operations, which allows local PV guests to cause a denial of service (host or guest malfunction) or possibly gain privileges via unspecified vectors.

CVE-2014-1666 [HIGH] CVE-2014-1666 xen: PHYSDEVOP_{prepare,release}_msix exposed to unprivileged guests
CVE-2014-1666 xen: PHYSDEVOP_{prepare,release}_msix exposed to unprivileged guests
The PHYSDEVOP_{prepare,release}_msix operations are supposed to be available to privileged guests (domain 0 in non-disaggregated setups) only, but the necessary privilege check was missing.
Malicious or misbehaving unprivileged guests can cause the host or other guests to malfunction. This can result in host-wide denial of service. Privilege escalation, while seeming to be unlikely, cannot be excluded.
