In shared resource environments (such as exists in some cloud services configurations), these vulnerabilities could allow one virtual machine to improperly access information from another. In non-browsing scenarios on standalone systems, an attacker would need prior access to the system or an ability to run a specially crafted application on the target system to leverage these vulnerabilities.\n\nThese vulnerabilities are known as:\n\n * CVE-2022-21123 - Shared Buffer Data Read (SBDR) \n * CVE-2022-21125 - Shared Buffer Data Sampling (SBDS)\n * CVE-2022-21127 - Special Register Buffer Data Sampling Update (SRBDS Update)\n * CVE-2022-21166 - Device Register Partial Write (DRPW)\n\n**Important**: These vulnerabilities might affect other operating systems and service providers. We advise customers to seek guidance from their respective vendors.\n\nMicrosoft has released software updates to help mitigate these vulnerabilities. To get all available protections, firmware (microcode) and software updates are required. Please check with your OEM for microcode updates. In some cases, installing these updates will have a performance impact. We have also acted to secure our cloud services.\n\nMicrosoft has no information to indicate that these vulnerabilities have been used to attack customers at this time. Microsoft continues working closely with industry partners including chip makers, hardware OEMs, and app vendors to protect customers.\n\n# Recommended Actions\n\nTo protect your system from these vulnerabilities, Microsoft recommends that you take the following actions, and refer to the subsequent sections for links to further information for your specific situation:\n\n 1. The best protection is to keep computers up to date. This includes installing OS and microcode updates.\n * To be fully protected, customers might also need to disable Hyper-Threading (also known as Simultaneous Multi Threading (SMT)). Please see [Knowledge Base Article 4073757](<https://support.microsoft.com/en-us/help/4073757/protect-your-windows-devices-against-spectre-meltdown>) for guidance on protecting Windows devices.\n * OEMs might also provide additional guidance. Customers using Surface products should see [Microsoft Knowledge Base Article 4073065](<https://support.microsoft.com/en-us/help/4073065/surface-guidance-to-protect-against-speculative-execution-side-channel>).\n 2. Microsoft recommends that enterprise customers review this advisory in detail and register for the security notifications mailer to be alerted of content changes to this advisory. See [Microsoft Technical Security Notifications](<https://technet.microsoft.com/en-us/security/dd252948>).\n 3. Verify the status of protections for the various CVEs by running the PowerShell script **Get-SpeculationControlSettings**. For more information and to obtain the PowerShell script see [Understanding Get-SpeculationControlSettings PowerShell script output](<https://support.microsoft.com/en-us/help/4074629/understanding-the-output-of-get-speculationcontrolsettings-powershell>).\n\n## Microsoft Windows client customers\n\nCustomers using Windows client operating systems need to apply both firmware (microcode) and software updates. See [Microsoft Knowledge Base Article 4073119](<https://support.microsoft.com/help/4073119>) for additional information. Microsoft is making available Intel-validated microcode updates for Windows 10 and 11 operating systems. Please see [Microsoft Knowledge Base Article 4093836](<https://support.microsoft.com/help/4093836>) for the current Intel microcode updates.\n\nIn addition, customers should check to see if their OEM is providing additional guidance on updates and mitigations. [Surface Support Article 4073065](<https://support.microsoft.com/en-us/help/4073065/surface-guidance-to-protect-against-speculative-execution-side-channel>) provides more information to Surface customers.\n\n## Microsoft Windows Server/Azure Stack HCI customers\n\nCustomers using Windows server operating systems listed in the Affected Products table need to apply firmware (microcode) and software updates as well as to configure protections. See [Microsoft Knowledge Base Article 4072698](<https://support.microsoft.com/help/4072698>) for additional information, including workarounds.\n\nMicrosoft Azure has taken steps to address the security vulnerabilities at the hypervisor level to protect Windows Server VMs running in Azure. More information can be found [here](<https://support.microsoft.com/en-us/help/4073235/cloud-protections-speculative-execution-side-channel-vulnerabilities>).\n\n## Microsoft cloud customers\n\nMicrosoft has already deployed mitigations across our cloud services. More information is available [here](<https://support.microsoft.com/help/4073235>).\n\n## Microsoft SQL Server customers\n\nIn scenarios running Microsoft SQL Server, customers should follow the guidance outlined in [Microsoft Knowledge Base Article 4073225](<https://support.microsoft.com/help/4073225>).\n\n## Potential performance impacts\n\nSpecific performance impact varies by hardware generation and implementation by the chip manufacturer. For most consumer devices, impact on performance may not be noticeable. Some customers might have to disable Hyper-Threading (SMT) to fully address the risk from Processor MMIO Stale Data vulnerabilities. In testing Microsoft has seen some performance impact with these mitigations, in particular when hyperthreading is disabled. Microsoft values the security of its software and services and has made the decision to implement certain mitigation strategies in an effort to better secure our products. In some cases, mitigations are not enabled by default to allow users and administrators to evaluate the performance impact and risk exposure before deciding to enable the mitigations. We continue to work with hardware vendors to improve performance while maintaining a high level of security.\n\n## References\n\nSee the following for further information from Intel:\n\n * Intel

This scheme is used to maintain invariants required for Xen's safety, e.g.\n PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately,\n the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too\n early and creates a window where the guest can re-establish the read/write mapping before writeability is\n prohibited.

This scheme is used to maintain\n invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables;\n updates need auditing by Xen. Unfortunately, Xen's safety logic doesn't account for CPU-induced cache non-\n coherency; cases where the CPU can cause the content of the cache to be different to the content in main\n memory. In such cases, Xen's safety logic can incorrectly conclude that the contents of a page is safe.\n (CVE-2022-26363, CVE-2022-26364)\n\n - Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution\n under certain microarchitecture-dependent conditions.
