• Addresses a race condition that causes the Local Security Authority Subsystem Service (LSASS) to stop working on Active Directory domain controllers.

The exception code is 0xc0000409 (STATUS_STACK_BUFFER_OVERRUN).

• Addresses an issue that might cause the Local Security Authority Server Service (LSASS) to leak tokens. This issue affects devices that have installed Windows updates dated June 14, 2022 or later. This issue occurs when the device performs a specific form of service for user (S4U) in a non-Trusted Computing Base (TCB) Windows service that runs as Network Service.

This long list of new features and fixes will be integrated in the security update for September 2022. The preview update is optional and is only offered when the user explicitly selects optional updates for installation in the settings page. The update can also be downloaded and installed from the Microsoft Update Catalog. The latest Servicing Stack Update (SSU) is included to fix various issues. Microsoft lists a known issue.
