only ARCH=arm affected, and this is already solved in recent version. CVE-2015-0268 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-0268): The vgic_v2_to_sgi function in arch/arm/vgic-v2.c in Xen 4.5.x, when running on ARM hardware with general interrupt controller (GIC) version 2, allows local guest users to cause a denial of service (host crash) by writing an invalid value to the GICD.SGIR register. |
