2018-05-08漏洞描述
在某些或所有操作系统内核的开发中，《英特尔64和IA-32体系结构软件开发人员手册》（SDM）的系统编程指南中的一条语句处理不当，导致MOV SS推迟了#DB异常的意外行为或POP SS，例如Windows，macOS，某些Xen配置或FreeBSD中的特权升级或Linux内核崩溃所证明的那样。 MOV至SS和POP SS指令禁止中断（包括NMI），数据断点和单步陷阱异常，直到下一条指令之后的指令边界为止（SDM第3A卷； 6.8.3节）。 （禁止的数据断点是MOV到SS或POP到SS指令本身访问的存储器上的断点。）请注意，调试异常不受中断允许（EFLAGS.IF）系统标志的禁止（SDM第3A卷；第2.3节） 。如果MOV到SS或POP到SS指令之后的指令是诸如SYSCALL，SYSENTER，INT 3等的指令，该指令以CPL <3的方式将控制权转移到操作系统，则调试异常将在转移到CPL <3的情况下传递。完成了。 OS内核可能不希望事件发生的顺序如此，因此发生时可能会遇到意外的行为。解决建议
