xen-kernel -- Information leak via internal x86 system device emulation

The Xen Project reports: Emulation routines in the hypervisor dealing with certain system devices check whether the access size by the guest is a supported one. When the access size is unsupported these routines failed to set the data to be returned to the guest for read accesses, so that...
