We advise customers seek guidance from their respective vendors. Important These issues will affect other systems such as Android, Chrome, iOS, and MacOS. They have been assigned the following CVEs:ĬVE-2018-11091 – “Microarchitectural Data Sampling Uncacheable Memory (MDSUM)”ĬVE-2018-12126 – “Microarchitectural Store Buffer Data Sampling (MSBDS)”ĬVE-2018-12127 – “Microarchitectural Fill Buffer Data Sampling (MFBDS)”ĬVE-2018-12130 – “Microarchitectural Load Port Data Sampling (MLPDS)” UPDATED ON May 14, 2019 On May 14, 2019, Intel published information about a new subclass of speculative execution side-channel vulnerabilities known as Microarchitectural Data Sampling. To learn more about this class of vulnerabilities, seeĪDV180002 | Guidance to mitigate speculative execution side-channel vulnerabilitiesĪDV180012 | Microsoft Guidance for Speculative Store Bypass We will continue to improve these mitigations against this class of vulnerabilities.

To get all available protections, firmware (microcode) and software updates are required. We are working closely with industry partners including chip makers, hardware OEMs, and application vendors to protect customers. We have not yet received any information to indicate that these vulnerabilities were used to attack customers.
See the following sections for more details. We have also taken action to secure our cloud services. We have released several updates to help mitigate these vulnerabilities. Therefore, we advise customers to seek guidance from those vendors. Note This issue also affects other operating systems, such as Android, Chrome, iOS, and macOS.
Microsoft is aware of a new publicly disclosed class of vulnerabilities that are called “speculative execution side-channel attacks” and that affect many modern processors including Intel, AMD, VIA, and ARM. Please check back here regularly for updates and new FAQ. This article will be updated as additional information becomes available.
