Description

**1\. Impacted Products** * VMware vCenter Server (VC) * VMware vSphere ESXi (ESXi) * VMware Workstation Pro / Player (WS) * VMware Fusion Pro / Fusion (Fusion) * vCloud Usage Meter (UM) * Identity Manager (vIDM) * vCenter Server (vCSA) * vSphere Data Protection (VDP) * vSphere Integrated Containers (VIC) * vRealize Automation (vRA) **2\. Introduction ** Intel has disclosed details on speculative-execution vulnerabilities known collectively as “Microarchitectural Data Sampling (MDS)" that can occur on Intel microarchitecture prior to 2nd Generation Intel® Xeon® Scalable Processors (formerly known as Cascade Lake). These issues may allow a malicious user who can locally execute code on a system to infer data otherwise protected by architectural mechanisms. There are four uniquely identifiable vulnerabilities associated with MDS: * CVE-2018-12126 - Microarchitectural Store Buffer Data Sampling (MSBDS) - CVSSv3 = 6.5 * CVE-2018-12130 - Microarchitectural Fill Buffer Data Sampling (MFBDS) - CVSSv3 = 6.5 * CVE-2018-12127 - Microarchitectural Load Port Data Sampling (MLPDS) - CVSSv3 = 6.5 * CVE-2019-11091 - Microarchitectural Data Sampling Uncacheable Memory (MDSUM) - CVSSv3 = 3.8 To assist in understanding speculative-execution vulnerabilities, VMware previously defined the following mitigation categories: * _Hypervisor-Specific Mitigations_ prevent information leakage from the hypervisor or guest VMs into a malicious guest VM. These mitigations require code changes for VMware products. * _Hypervisor-Assisted Guest Mitigations _virtualize new speculative-execution hardware control mechanisms for guest VMs so that Guest OSes can mitigate leakage between processes within the VM. These mitigations require code changes for VMware products. * _Operating System-Specific Mitigations_ are applied to guest operating systems. These updates will be provided by a 3rd party vendor or in the case of VMware Virtual Appliances, by VMware. * _Microcode Mitigations_ are applied to a system’s processor(s) by a microcode update from the hardware vendor. These mitigations do not require hypervisor or guest operating system updates to be effective. MDS vulnerabilities require _Hypervisor-Specific Mitigations_ (described in section 3a.) _Hypervisor-Assisted Guest Mitigations_ (described in section 3b.) and _Operating System-Specific Mitigations_ (described in section 3c.) **3a. _Hypervisor-Specific Mitigations_ for MDS vulnerabilities - CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, and CVE-2019-11091 ** **Description: ** vCenter Server, ESXi, Workstation, and Fusion updates include _Hypervisor-Specific Mitigations_ for MDS speculative execution vulnerabilities. VMware has evaluated the severity of these issues to be in the [Moderate severity range](<https://www.vmware.com/support/policies/security_response.html>) with a maximum CVSSv3 base score of 6.5. **Known Attack Vectors: ** A malicious user must have local access to a virtual machine and the ability to execute code to infer data otherwise protected by architectural mechanisms from another virtual machine or the hypervisor itself via MDS vulnerabilities. There are two known attack vector variants for MDS at the Hypervisor level: * _Sequential-context attack vector_ (Inter-VM): a malicious VM can potentially infer recently accessed data of a previous context (hypervisor thread or other VM thread) on either logical processor of a processor core. * _Concurrent-context attack vector_ (Inter-VM): a malicious VM can potentially infer recently accessed data of a concurrently executing context (hypervisor thread or other VM thread) on the other logical processor of the Hyper-Threading-enabled processor core. **Resolution:** * The _Sequential-context attack vector_ (Inter-VM): is mitigated by a Hypervisor update to the product versions listed in the table below. These mitigations are dependent on Intel microcode updates (provided in separate ESXi patches for most Intel hardware platforms) listed in the table below. This mitigation is enabled by default and does not impose a significant performance impact. * The _Concurrent-context attack vector_ (Inter-VM): is mitigated through enablement of the ESXi Side-Channel-Aware Scheduler Version 1 or Version 2. These options may impose a non-trivial performance impact and are not enabled by default. **Workarounds:** * There are no known Hypervisor-Specific workarounds for the MDS class of vulnerabilities. **Additional Documentation:** * vSphere: [KB67577](<https://kb.vmware.com/kb/67577>) should be thoroughly reviewed to ensure a strong understanding of the _Hypervisor-Specific Mitigations_ enablement process for MDS and potential CPU capacity impacts * Workstation/Fusion: [KB68025](<https://kb.vmware.com/kb/68025>) should be thoroughly reviewed to ensure a strong understanding of the _Hypervisor-Specific Mitigations_ enablement process for MDS and potential CPU capacity impacts. **Notes: ** * VMware Hypervisors running on 2nd Generation Intel® Xeon® Scalable Processors (formerly known as Cascade Lake) are not affected by MDS vulnerabilities. **Acknowledgements:** * None. **Resolution Matrix: ** Product | Version | Running On | CVE Identifier | CVSSv3 | Severity | Fixed

{"nessus": [{"lastseen": "2023-02-10T14:54:58", "description": "An update for qemu-kvm is now available for Red Hat Enterprise Linux 6.\n\nRed Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nKernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.\n\nSecurity Fix(es) :\n\n* A flaw was found in the implementation of the 'fill buffer', a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a aEUR~load portaEURtm subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPUaEURtms pipelines.\nStale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.

A Common Vulnerability Scoring System (CVSS) base\nscore, which gives a detailed severity rating, is available for each\nvulnerability from the CVE link(s) in the References section.\n\nKernel-based Virtual Machine (KVM) is a full virtualization solution\nfor Linux on a variety of architectures. The qemu-kvm packages provide\nthe user-space component for running virtual machines that use KVM.\n\nSecurity Fix(es) :\n\n* A flaw was found in the implementation of the 'fill buffer', a\nmechanism used by modern CPUs when a cache-miss is made on L1 CPU\ncache. If an attacker can generate a load operation that would create\na page fault, the execution will continue speculatively with incorrect\ndata from the fill buffer while the data is fetched from higher level\ncaches. This response time can be measured to infer data in the fill\nbuffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level\nmicro-optimizations to improve the performance of writing data back to\nCPU caches. The write operation is split into STA (STore Address) and\nSTD (STore Data) sub-operations. These sub-operations allow the\nprocessor to hand-off address generation logic into these\nsub-operations for optimized writes. Both of these sub-operations\nwrite to a shared distributed processor structure called the\n'processor store buffer'. As a result, an unprivileged attacker could\nuse this flaw to read private data resident within the CPU's processor\nstore buffer. (CVE-2018-12126)\n\n* Microprocessors use a aEUR~load portaEURtm subcomponent to perform load\noperations from memory or IO. During a load operation, the load port\nreceives data from the memory or IO subsystem and then provides the\ndata to the CPU registers and operations in the CPUaEURtms pipelines.\nStale load operations results are stored in the 'load port' table\nuntil overwritten by newer operations. Certain load-port operations\ntriggered by an attacker can be used to reveal data about previous\nstale requests leaking data back to the attacker via a timing\nside-channel. (CVE-2018-12127)\n\n* Uncacheable memory on some microprocessors utilizing speculative\nexecution may allow an authenticated user to potentially enable\ninformation disclosure via a side channel with local access.\n(CVE-2019-11091)\n\nFor more details about the security issue(s), including the impact, a\nCVSS score, acknowledgments, and other related information, refer to\nthe CVE page(s) listed in the References section.\n\nNote that Tenable Network Security has attempted to extract the\npreceding description block directly from the corresponding Red Hat\nsecurity advisory.

flaw was found in the implementation of the 'fill buffer', a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer.\n (CVE-2018-12130)\n\n - Modern Intel microprocessors implement hardware-level micro- optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n - Microprocessors use a load port subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPUs pipelines.

If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a 'load port' subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU's pipelines.\nStale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.

The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.\n\nSecurity Fix(es) :\n\n* A flaw was found in the implementation of the 'fill buffer', a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a 'load port' subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU's pipelines.\nStale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.

This response time can be measured to infer data in the fill\nbuffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level\nmicro-optimizations to improve the performance of writing data back to\nCPU caches. The write operation is split into STA (STore Address) and\nSTD (STore Data) sub-operations. These sub-operations allow the\nprocessor to hand-off address generation logic into these\nsub-operations for optimized writes. Both of these sub-operations\nwrite to a shared distributed processor structure called the\n'processor store buffer'. As a result, an unprivileged attacker could\nuse this flaw to read private data resident within the CPU's processor\nstore buffer. (CVE-2018-12126)\n\n* Microprocessors use a 'load port' subcomponent to perform load\noperations from memory or IO. During a load operation, the load port\nreceives data from the memory or IO subsystem and then provides the\ndata to the CPU registers and operations in the CPU's pipelines.\nStale load operations results are stored in the 'load port' table\nuntil overwritten by newer operations. Certain load-port operations\ntriggered by an attacker can be used to reveal data about previous\nstale requests leaking data back to the attacker via a timing\nside-channel. (CVE-2018-12127)\n\n* Uncacheable memory on some microprocessors utilizing speculative\nexecution may allow an authenticated user to potentially enable\ninformation disclosure via a side channel with local access.\n(CVE-2019-11091)\n\nFor more details about the security issue(s), including the impact, a\nCVSS score, acknowledgments, and other related information, refer to\nthe CVE page(s) listed in the References section.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/security/vulnerabilities/mds\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/errata/RHSA-2019:1207\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/security/cve/cve-2018-12126\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/security/cve/cve-2018-12127\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/security/cve/cve-2018-12130\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://access.redhat.com/security/cve/cve-2019-11091\"\n );\n script_set_attribute(\n attribute:\"solution\", \n value:\n\"Update the affected redhat-release-virtualization-host,\nredhat-virtualization-host-image-update and / or\nredhat-virtualization-host-image-update-placeholder packages.\"\n );\n script_set_cvss_base_vector(\"CVSS2#AV:L/AC:M/Au:N/C:C/I:N/A:N\");\n script_set_cvss_temporal_vector(\"CVSS2#E:U/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:U/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2019-11091\");\n script_set_attribute(attribute:\"exploitability_ease\", value:\"No known exploits are available\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:redhat-release-virtualization-host\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:redhat-virtualization-host-image-update\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:redhat:enterprise_linux:redhat-virtualization-host-image-update-placeholder\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:redhat:enterprise_linux:7\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2019/05/30\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2019/05/14\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2019/05/16\");\n script_set_attribute(attribute:\"in_the_news\", value:\"true\");\n script_set_attribute(attribute:\"generated_plugin\", value:\"current\");\n script_set_attribute(attribute:\"stig_severity\", value:\"I\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_copyright(english:\"This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n script_family(english:\"Red Hat Local Security Checks\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/RedHat/release\", \"Host/RedHat/rpm-list\", \"Host/cpu\");\n\n exit(0);\n}\n\n\ninclude(\"audit.inc\");\ninclude(\"global_settings.inc\");\ninclude(\"misc_func.inc\");\ninclude(\"rpm.inc\");\n\nif (!get_kb_item(\"Host/local_checks_enabled\")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nrelease = get_kb_item(\"Host/RedHat/release\");\nif (isnull(release) || \"Red Hat\" >!< release) audit(AUDIT_OS_NOT, \"Red Hat\");\nos_ver = pregmatch(pattern: \"Red Hat Enterprise Linux.*release ([0-9]+(\\.[0-9]+)?)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, \"Red Hat\");\nos_ver = os_ver[1];\nif (!

for qemu-kvm is now available for Red Hat Enterprise Linux 7.5 Extended Update Support.\n\nRed Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nKernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.\n\nSecurity Fix(es) :\n\n* A flaw was found in the implementation of the 'fill buffer', a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a 'load port' subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU's pipelines.\nStale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.

rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe rhvm-setup-plugins package adds functionality exclusive only to Red Hat Virtualization Manager, and is not available for the upstream ovirt-engine. It includes the configuration of the Red Hat Support plugin, copying downstream-only artifacts to the ISO domain, and links to the knowledgebase and other support material.\n\nSecurity Fix(es) :\n\n* A flaw was found in the implementation of the 'fill buffer', a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a 'load port' subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU's pipelines.\nStale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.

rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe rhvm-setup-plugins package adds functionality exclusive only to Red Hat Virtualization Manager, and is not available for the upstream ovirt-engine. It includes the configuration of the Red Hat Support plugin, copying downstream-only artifacts to the ISO domain, and links to the knowledgebase and other support material.\n\nSecurity Fix(es) :\n\n* A flaw was found in the implementation of the 'fill buffer', a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a 'load port' subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU's pipelines.\nStale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel. (CVE-2018-12127)\n\n* Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.\n(CVE-2019-11091)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.", "cvss3": {}, "published": "2019-05-16T00:00:00", "type": "nessus", "title": "RHEL 7 : Virtualization Manager (RHSA-2019:1205) (MDSUM/RIDL) (MFBDS/RIDL/ZombieLoad) (MLPDS/RIDL) (MSBDS/Fallout)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2018-12126", "CVE-2018-12127", "CVE-2018-12130", "CVE-2019-11091"], "modified": "2020-01-15T00:00:00", "cpe": ["p-cpe:/a:redhat:enterprise_linux:rhvm-setup-plugins", "cpe:/o:redhat:enterprise_linux:7"], "id": "REDHAT-RHSA-2019-1205.NASL", "href": "https://www.tenable.com/plugins/nessus/125195", "sourceData": "#\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were \n# extracted from Red Hat Security Advisory RHSA-2019:1205.

If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a 'load port' subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU's pipelines.\nStale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel.
