Vetor base

AV:A/AC:L/Au:S/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Xen versions 4.2.x through 4.4.x

Description The issue arises from the HVMOP inject msi function not properly checking the return value from the IRQ setup check. This allows local HVM guest administrators to cause a denial of service, resulting in a NULL pointer dereference and crash.

Recommendations For Xen versions 4.2.x through 4.4.x, consider restricting access to the HVMOP inject msi function as a temporary workaround until a patch is available.
