A flaw was found in the Linux kernel before version 4.12 in the way the KVM
module processed the trap flag(TF) bit in EFLAGS during emulation of the
syscall instruction, which leads to a debug exception(#DB) being raised in
the guest stack. A user/process inside a guest could use this flaw to
potentially escalate their privileges inside the guest. Linux guests are
not affected by this.
