Summary
A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.
Severity

          "value": "A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer\u0027s Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL \u003c 3, the debug exception is delivered after the transfer to CPL \u003c 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs."

The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL \u003c 3, the debug exception is delivered after the transfer to CPL \u003c 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs."

The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL \u003c 3, the debug exception is delivered after the transfer to CPL \u003c 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.\"},{\"lang\":\"es\",\"value\":\"Una declaraci\u00f3n en la gu\u00eda de programaci\u00f3n de sistemas del Manual del desarrollador de software (SDM) de las arquitecturas Intel 64 e IA-32 se manej\u00f3 incorrectamente en el desarrollo de algunos o todos los n\u00facleos del sistema operativo, lo que provoc\u00f3 un comportamiento inesperado para las excepciones #DB que son diferidas por MOV SS o POP SS, tal y como queda demostrado con (por ejemplo) el escalado de privilegios en Windows, macOS, algunas configuraciones Xen o FreeBSD, o un fallo del kernel de Linux. Las instrucciones de MOV a SS y POP SS inhiben interrupciones (incluyendo NMI), puntos de interrupci\u00f3n de datos y excepciones de trampas de un paso hasta los l\u00edmites de la instrucci\u00f3n que siguen a la siguiente instrucci\u00f3n (SDM Vol. 3A; secci\u00f3n 6.8.3). (Los puntos de interrupci\u00f3n de datos inhibidos son aquellos en la memoria a los que accede a la propia instrucci\u00f3n MOV a SS o POP a SS).
