The em_syscall function in arch/x86/kvm/emulate.c in the KVM implementation in the Linux kernel prior to 3.2.14 does not properly handle the 0f05 (aka syscall) opcode, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application, as demonstrated by an NASM file.
