Processor MMIO Stale Data Vulnerabilities
|
||||
=========================================
|
||||
|
||||
Processor MMIO Stale Data Vulnerabilities are a class of memory-mapped I/O
|
||||
(MMIO) vulnerabilities that can expose data. The sequences of operations for
|
||||
exposing data range from simple to very complex. Because most of the
|
||||
vulnerabilities require the attacker to have access to MMIO, many environments
|
||||
are not affected. System environments using virtualization where MMIO access is
|
||||
provided to untrusted guests may need mitigation. These vulnerabilities are
|
||||
not transient execution attacks. However, these vulnerabilities may propagate
|
||||
stale data into core fill buffers where the data can subsequently be inferred
|
||||
by an unmitigated transient execution attack. Mitigation for these
|
||||
vulnerabilities includes a combination of microcode update and software
|
||||
changes, depending on the platform and usage model. Some of these mitigations
|
||||
are similar to those used to mitigate Microarchitectural Data Sampling (MDS) or
|
||||
those used to mitigate Special Register Buffer Data Sampling (SRBDS).
|
||||
|
||||
Data Propagators
|
||||
================
|
||||
Propagators are operations that result in stale data being copied or moved from
|
||||
one microarchitectural buffer or register to another. Processor MMIO Stale Data
|
||||
Vulnerabilities are operations that may result in stale data being directly
|
||||
read into an architectural, software-visible state or sampled from a buffer or
|
||||
register.
|
||||
|
||||
Fill Buffer Stale Data Propagator (FBSDP)
|
||||
-----------------------------------------
|
||||
Stale data may propagate from fill buffers (FB) into the non-coherent portion
|
||||
of the uncore on some non-coherent writes. Fill buffer propagation by itself
|
||||
does not make stale data architecturally visible. Stale data must be propagated
|
||||
to a location where it is subject to reading or sampling.
|
||||
|
||||
Sideband Stale Data Propagator (SSDP)
|
||||
-------------------------------------
|
||||
The sideband stale data propagator (SSDP) is limited to the client (including
|
||||
Intel Xeon server E3) uncore implementation. The sideband response buffer is
|
||||
shared by all client cores. For non-coherent reads that go to sideband
|
||||
destinations, the uncore logic returns 64 bytes of data to the core, including
|
||||
both requested data and unrequested stale data, from a transaction buffer and
|
||||
the sideband response buffer. As a result, stale data from the sideband
|
||||
response and transaction buffers may now reside in a core fill buffer.
|
||||
|
||||
Primary Stale Data Propagator (PSDP)
|
||||
------------------------------------
|
||||
The primary stale data propagator (PSDP) is limited to the client (including
|
||||
Intel Xeon server E3) uncore implementation. Similar to the sideband response
|
||||
buffer, the primary response buffer is shared by all client cores. For some
|
||||
processors, MMIO primary reads will return 64 bytes of data to the core fill
|
||||
buffer including both requested data and unrequested stale data. This is
|
||||
similar to the sideband stale data propagator.
|
||||
|
||||
Vulnerabilities
|
||||
===============
|
||||
Device Register Partial Write (DRPW) (CVE-2022-21166)
|
||||
-----------------------------------------------------
|
||||
Some endpoint MMIO registers incorrectly handle writes that are smaller than
|
||||
the register size. Instead of aborting the write or only copying the correct
|
||||
subset of bytes (for example, 2 bytes for a 2-byte write), more bytes than
|
||||
specified by the write transaction may be written to the register. On
|
||||
processors affected by FBSDP, this may expose stale data from the fill buffers
|
||||
of the core that created the write transaction.
|
||||
|
||||
Shared Buffers Data Sampling (SBDS) (CVE-2022-21125)
|
||||
----------------------------------------------------
|
||||
After propagators may have moved data around the uncore and copied stale data
|
||||
into client core fill buffers, processors affected by MFBDS can leak data from
|
||||
the fill buffer. It is limited to the client (including Intel Xeon server E3)
|
||||
uncore implementation.
|
||||
|
||||
Shared Buffers Data Read (SBDR) (CVE-2022-21123)
|
||||
------------------------------------------------
|
||||
It is similar to Shared Buffer Data Sampling (SBDS) except that the data is
|
||||
directly read into the architectural software-visible state. It is limited to
|
||||
the client (including Intel Xeon server E3) uncore implementation.
|
||||
|
||||
Affected Processors
|
||||
===================
|
||||
Not all the CPUs are affected by all the variants. For instance, most
|
||||
processors for the server market (excluding Intel Xeon E3 processors) are
|
||||
impacted by only Device Register Partial Write (DRPW).
|
||||
|
||||
Below is the list of affected Intel processors [#f1]_:

|
||||
=================== ============ =========
|
||||
|
||||
If a CPU is in the affected processor list, but not affected by a variant, it
|
||||
is indicated by new bits in MSR IA32_ARCH_CAPABILITIES. As described in a later
|
||||
section, mitigation largely remains the same for all the variants, i.e. to
|
||||
clear the CPU fill buffers via VERW instruction.
|
||||
|
||||
New bits in MSRs
|
||||
================
|
||||
Newer processors and microcode update on existing affected processors added new
|
||||
bits to IA32_ARCH_CAPABILITIES MSR. These bits can be used to enumerate
|
||||
specific variants of Processor MMIO Stale Data vulnerabilities and mitigation
|
||||
capability.
|
||||
|
||||
MSR IA32_ARCH_CAPABILITIES
|
||||
--------------------------
|
||||
Bit 13 - SBDR_SSDP_NO - When set, processor is not affected by either the
|
||||
Shared Buffers Data Read (SBDR) vulnerability or the sideband stale
|
||||
data propagator (SSDP).
|
||||
Bit 14 - FBSDP_NO - When set, processor is not affected by the Fill Buffer
|
||||
Stale Data Propagator (FBSDP).
|
||||
Bit 15 - PSDP_NO - When set, processor is not affected by Primary Stale Data
|
||||
Propagator (PSDP).
|
||||
Bit 17 - FB_CLEAR - When set, VERW instruction will overwrite CPU fill buffer
|
||||
values as part of MD_CLEAR operations. Processors that do not
|
||||
enumerate MDS_NO (meaning they are affected by MDS) but that do
|
||||
enumerate support for both L1D_FLUSH and MD_CLEAR implicitly enumerate
|
||||
FB_CLEAR as part of their MD_CLEAR support.
|
||||
Bit 18 - FB_CLEAR_CTRL - Processor supports read and write to MSR
|
||||
IA32_MCU_OPT_CTRL[FB_CLEAR_DIS]. On such processors, the FB_CLEAR_DIS
|
||||
bit can be set to cause the VERW instruction to not perform the
|
||||
FB_CLEAR action. Not all processors that support FB_CLEAR will support
|
||||
FB_CLEAR_CTRL.
|
||||
|
||||
MSR IA32_MCU_OPT_CTRL
|
||||
---------------------
|
||||
Bit 3 - FB_CLEAR_DIS - When set, VERW instruction does not perform the FB_CLEAR
|
||||
action. This may be useful to reduce the performance impact of FB_CLEAR in
|
||||
cases where system software deems it warranted (for example, when performance
|
||||
is more critical, or the untrusted software has no MMIO access). Note that
|
||||
FB_CLEAR_DIS has no impact on enumeration (for example, it does not change
|
||||
FB_CLEAR or MD_CLEAR enumeration) and it may not be supported on all processors
|
||||
that enumerate FB_CLEAR.
|
||||
|
||||
Mitigation
|
||||
==========
|
||||
Like MDS, all variants of Processor MMIO Stale Data vulnerabilities have the
|
||||
same mitigation strategy to force the CPU to clear the affected buffers before
|
||||
an attacker can extract the secrets.
|
||||
|
||||
This is achieved by using the otherwise unused and obsolete VERW instruction in
|
||||
combination with a microcode update. The microcode clears the affected CPU
|
||||
buffers when the VERW instruction is executed.
|
||||
|
||||
Kernel reuses the MDS function to invoke the buffer clearing:
|
||||
|
||||
mds_clear_cpu_buffers()
|
||||
|
||||
On MDS affected CPUs, the kernel already invokes CPU buffer clear on
|
||||
kernel/userspace, hypervisor/guest and C-state (idle) transitions. No
|
||||
additional mitigation is needed on such CPUs.
|
||||
|
||||
For CPUs not affected by MDS or TAA, mitigation is needed only for the attacker
|
||||
with MMIO capability. Therefore, VERW is not required for kernel/userspace. For
|
||||
virtualization case, VERW is only needed at VMENTER for a guest with MMIO
|
||||
capability.
|
||||
|
||||
Mitigation points
|
||||
-----------------
|
||||
Return to user space
|
||||
^^^^^^^^^^^^^^^^^^^^
|
||||
Same mitigation as MDS when affected by MDS/TAA, otherwise no mitigation
|
||||
needed.
|
||||
|
||||
C-State transition
|
||||
^^^^^^^^^^^^^^^^^^
|
||||
Control register writes by CPU during C-state transition can propagate data
|
||||
from fill buffer to uncore buffers. Execute VERW before C-state transition to
|
||||
clear CPU fill buffers.
|
||||
|
||||
Guest entry point
|
||||
^^^^^^^^^^^^^^^^^
|
||||
Same mitigation as MDS when processor is also affected by MDS/TAA, otherwise
|
||||
execute VERW at VMENTER only for MMIO capable guests. On CPUs not affected by
|
||||
MDS/TAA, guest without MMIO access cannot extract secrets using Processor MMIO
|
||||
Stale Data vulnerabilities, so there is no need to execute VERW for such guests.
|
||||
|
||||
Mitigation control on the kernel command line
|
||||
---------------------------------------------
|
||||
The kernel command line allows to control the Processor MMIO Stale Data
|
||||
mitigations at boot time with the option "mmio_stale_data=". The valid
|
||||
arguments for this option are:
|
||||
|
||||
========== =================================================================
|
||||
full If the CPU is vulnerable, enable mitigation; CPU buffer clearing
|
||||
on exit to userspace and when entering a VM. Idle transitions are
|
||||
protected as well. It does not automatically disable SMT.
|
||||
full,nosmt Same as full, with SMT disabled on vulnerable CPUs. This is the
|
||||
complete mitigation.
|
||||
off Disables mitigation completely.
|
||||
========== =================================================================
|
||||
|
||||
If the CPU is affected and mmio_stale_data=off is not supplied on the kernel
|
||||
command line, then the kernel selects the appropriate mitigation.
|
||||
|
||||
Mitigation status information
|
||||
-----------------------------
|
||||
The Linux kernel provides a sysfs interface to enumerate the current
|
||||
vulnerability status of the system: whether the system is vulnerable, and
|
||||
which mitigations are active. The relevant sysfs file is:
|
||||
|
||||
/sys/devices/system/cpu/vulnerabilities/mmio_stale_data
|
||||
|
||||
The possible values in this file are:
|
||||
|
||||
.. list-table::
|
||||
|
||||
* - 'Not affected'
|
||||
- The processor is not vulnerable
|
||||
* - 'Vulnerable'
|
||||
- The processor is vulnerable, but no mitigation enabled
|
||||
* - 'Vulnerable: Clear CPU buffers attempted, no microcode'
|
||||
- The processor is vulnerable, but microcode is not updated. The
|
||||
mitigation is enabled on a best effort basis.
|
||||
* - 'Mitigation: Clear CPU buffers'
|
||||
- The processor is vulnerable and the CPU buffer clearing mitigation is
|
||||
enabled.
|
||||
|
||||
If the processor is vulnerable then the following information is appended to
|
||||
the above information:
|
||||
|
||||
======================== ===========================================
|
||||
'SMT vulnerable' SMT is enabled
|
||||
'SMT disabled' SMT is disabled

||||

[X86,INTEL] Control mitigation for the Processor
|
||||
MMIO Stale Data vulnerabilities.
|
||||
|
||||
Processor MMIO Stale Data is a class of
|
||||
vulnerabilities that may expose data after an MMIO
|
||||
operation. Exposed data could originate or end in
|
||||
the same CPU buffers as affected by MDS and TAA.
|
||||
Therefore, similar to MDS and TAA, the mitigation
|
||||
is to clear the affected CPU buffers.
|
||||
|
||||
This parameter controls the mitigation. The
|
||||
options are:
|
||||
|
||||
full - Enable mitigation on vulnerable CPUs
|
||||
|
||||
full,nosmt - Enable mitigation and disable SMT on
|
||||
vulnerable CPUs.
|
||||
|
||||
off - Unconditionally disable mitigation
|
||||
|
||||
On MDS or TAA affected machines,
|
||||
mmio_stale_data=off can be prevented by an active
|
||||
MDS or TAA mitigation as these vulnerabilities are
|
||||
mitigated with the same mechanism so in order to
|
||||
disable this mitigation, you need to specify
|
||||
mds=off and tsx_async_abort=off too.
|
||||
|
||||
Not specifying this option is equivalent to
|
||||
mmio_stale_data=full.
