Issue with Kerberos requests on domain controllers may cause LSASS memory leaks

Following installation of the March 2024 security update, released March 12, 2024 (KB5035857), Local Security Authority Subsystem Service (LSASS) may experience a memory leak on domain controllers (DCs). This is observed when on-premises and cloud-based Active Directory Domain Controllers service Kerberos authentication requests.

Extreme memory leaks may cause LSASS to crash, which triggers an unscheduled reboot of underlying domain controllers (DCs).

Note: This issue does not occur on Home devices. It affects only environments in organizations using some Windows Server platforms.

Resolution: This issue was resolved in the out-of-band (OOB) update KB5037422, which is only available via the Microsoft Update Catalog. We strongly recommend you do not apply the March 2024 security update on DCs and install KB5037422 instead. As this is a cumulative update, you do not need to apply any previous update before installing KB5037422. To install this update, search for KB5037422 in the Microsoft Update Catalog. The OOB update can then be manually imported to Windows Server Update Services (WSUS) and Configuration Manager. For guidance, see WSUS and the Microsoft Update Catalog.

If you manage update catalogs in Configuration Manager, please check the section Import updates. If you with you work with software update synchronization in Configuration Manager, review the steps on Import updates from the Microsoft Update Catalog. For more information about the Microsoft Update Catalog, visit Microsoft Update Catalog - FAQs

Important: This update (KB5037422) is not available from Windows Update and will not install automatically.

Devices attempting to install the January 2024 Windows Recovery Environment update (KB5034439) might display an error related to the size of the Recovery Environment's partition. The Windows Recovery Environment (WinRE) is used to repair or recover from issues affecting Windows.

Resulting from this error, the following message might be displayed.

  • ​"0x80070643 - ERROR_INSTALL_FAILURE"

Important: If your Windows device does not have a recovery environment configured, you do not need this update (KB5034439). In this case, the error can be ignored.

To determine whether your device has a recovery environment configured, inspect the WinRE status by following these steps:

  1. ​Open a Command Prompt window (cmd) as admin.
  2. ​To check the WinRE status, run reagentc /info. If the WinRE is configured, a "Windows RE status" field will appear in the output, with value "Enabled". If WinRE is not configured, this field will have the value "Disabled".

Workaround: It might be necessary to increase the size of the WinRE partition in order to avoid this issue and complete the installation. Note that 250 megabytes of free space is required in the recovery partition. Devices which do not have sufficient free space in the recovery partition can use a script to extend the partition size. A sample script has been provided in the documentation for adding an update package to WinRE, Extend the Windows RE Partition. Guidance to manually change the WinRE partition size can additionally be found in KB5028997: Instructions to manually resize your partition to install the WinRE update.

Next steps: We are working on a resolution and will provide an update in an upcoming release.

Affected platforms:

  • ​Client: Windows 11, version 21H2; Windows 10, version 22H2; Windows 10, version 21H2

Devices with locale set to Croatia might not utilize the expected currency

The correct default currency might not display or be used in Windows devices which have locale set to Croatia. This can affect applications which retrieve the device's currency for purchases or other transactions. 

Earlier this year, Croatia joined the Eurozone, changing its currency from the Kuna to Euro. Windows Locale data for Croatia will be updated for this change in the short term.

Workaround: Changing the currency in Windows can help. This can be accomplished via the Windows Control Panel.

  1. ​Open the "Windows Region" settings. This can be done in one of the following ways:
    1. ​Open "Control Panel" from the start menu and select "Change date, time, or number formats" under "Clock and Region"
    2. ​On your keyboard, press and hold the Windows key, then press the letter R. This will open the "Run" window. Type INTL.CPL into the Open field,
  2. ​In the Region settings, choose one of the 2 locales for Croatia:
    1. Croatian (Bosnia & Herzegovina)
    2. Croatian (Croatia)
  3. ​In this same window, click the "Additional settings" button. Once there, click the "Currency" tab.
  4. ​Change the currency symbol from "KN" to Euro, ""

Additional information can be seen here: Currency formatting - Globalization | Microsoft Learn.

Manually changing currency might also be an option in some applications. Although this won't change the device’s default currency, this could allow usage of the application with the desired currency preference. Some applications might not allow this manual change. Please view the settings and documentation for your applications.

Resolution: This issue was resolved in updates released March 12, 2024 (KB5035857) and later. We recommend you install the latest security update for your device as it contains important improvements and issue resolutions, including this one.

After installing KB5009555 or any updates released January 11, 2022 and later on your domain controllers, scenarios which rely on Read-only domain controllers (RODCs) or synthetic RODC machine accounts might fail to establish a Netlogon secure channel. RODC accounts must have a linked and compliant KRBTGT account to successfully establish a secure channel. Affected applications or network appliances, such as Riverbed SteelHead WAN Optimizers, might have issues joining domains or limitations after joining a domain.

Next Steps: Affected apps and network appliances will need an update from their developer or manufacturer to resolve this issue. Microsoft and Riverbed are presently investigating and will provide an update when more information is available.

Affected platforms:

  • ​Server: Windows Server 2022; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012; Windows Server 2008 R2 SP1; Windows Server 2008 SP2
