From NVD
The em_sysenter function in arch/x86/kvm/emulate.c in the Linux kernel before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows guest OS users to gain guest OS privileges or cause a denial of service (guest OS crash) by triggering use of a 16-bit code segment for emulation of a SYSENTER instruction.

在Linux内核3.18.5之前，arch/x86/kvm/emulate.c中的em_sysenter函数允许 guest OS 用户获得 guest OS 权限或通过触发使用一个16位代码段来模拟SYSENTER指令造成服务拒绝(guest OS崩溃)。
