CVE-2013-2078 kernel: xen: Hypervisor crash due to missing exception recovery on XSETBV
Processors do certain validity checks on the register values passed to XSETBV. For the PV emulation path for that instruction the hypervisor code didn't check for certain invalid bit combinations, thus exposing itself to a fault occurring when invoking that instruction on behalf of the guest.
Malicious or buggy unprivileged user space can cause the entire host to crash.
