KVM: x86: fix emulation of "MOV SS, null selector"
This is CVE-2017-2583. On Intel this causes a failed vmentry because
SS's type is neither 3 nor 7 (even though the manual says this check is
only done for usable SS, and the dmesg splat says that SS is unusable!).
On AMD it's worse: svm.c is confused and sets CPL to 0 in the vmcb.
The fix fabricates a data segment descriptor when SS is set to a null
selector, so that CPL and SS.DPL are set correctly in the VMCS/vmcb.
Furthermore, only allow setting SS to a NULL selector if SS.RPL

Kernel: Kvm: vmx/svm potential privilege escalation inside guest
The load_segment_descriptor implementation in arch/x86/kvm/emulate.c in the Linux kernel before 4.9.5 improperly emulates a "MOV SS, NULL selector" instruction, which allows guest OS users to cause a denial of service (guest OS crash) or gain guest OS privileges via a crafted application.
Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support was vulnerable to an incorrect segment selector(SS) value error. The error could occur while loading values into the SS register in long mode. A user or process inside a guest could use this flaw to crash the guest, resulting in DoS or potentially escalate their privileges inside the guest.

CVE-2017-2583 Kernel: Kvm: vmx/svm potential privilege escalation inside guest
Linux kernel built with the Kernel-based Virtual Machine(CONFIG_KVM) support
is vulnerable an incorrect segment selector(SS) value error. It could occur
loading values into SS register in long mode.
A user/process inside guest could use this flaw to crash the guest resulting
in DoS or potentially escalate their privileges inside guest.
Upstream patch:
-> https://git.kernel.org/linus/33ab91103b3415e12457e3104f0e4517ce12d0f3
Note: On Intel CPUs it'd corrupt the guest state resulting in DoS; Whereas on
AMD CPUs it could potentially escalate privileges inside guest.
