Summary

A Kernel Streaming Service Driver Elevation of Privilege Vulnerability has been identified in multiple versions of Microsoft Windows. This vulnerability is related to a race condition, specifically involving concurrent execution using shared resources with improper synchronization.

Impact

If exploited, this vulnerability could allow an attacker with low privileges to elevate their privileges on the affected system. The impact is severe, with potential for high levels of compromise to confidentiality, integrity, and availability of the system. An attacker could potentially gain administrative control, access sensitive information, modify system settings, or disrupt normal operations.

Exploitation

There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.

Patch

Patches are available. Microsoft has released updates to address this vulnerability across multiple affected Windows versions, including Windows 10, Windows 11, and various Windows Server editions.

Mitigation

1. Apply the latest security updates provided by Microsoft for the affected Windows versions. 2. Ensure that all Windows systems are updated to the following versions or newer: - Windows 10 version 22H2: 10.0.19045.4651 - Windows 11 version 22H2: 10.0.22621.3880 - Windows Server 2012 R2: Latest update - Windows Server 2022 version 23H2: 10.0.25398.1009 - Windows 11 version 21H2: 10.0.22000.3079 - Windows Server 2019: 10.0.17763.6054 - Windows Server 2016: 10.0.14393.7159 - Windows 10 version 21H2: 10.0.19044.4651 - Windows 11 version 23H2: 10.0.22631.3880 - Windows 10 version 1607: 10.0.14393.7159 - Windows Server 2008 R2 SP1 and Windows Server 2008 SP2: Latest update - Windows Server 2022: 10.0.20348.2582 - Windows 10 version 1809: 10.0.17763.6054 3.

VERT Threat Alert: August 2024 Patch Tuesday Analysis
While updates for CVE-2024-38200 were released as part of the August Patch Tuesday drop, Microsoft had already enabled a fix for this issue on July 30, meaning that all users of supported versions of Office were protected. This vulnerability, a privilege escalation in the Windows Kernel, requires that the attacker win a race condition to successfully exploit it.

August Patch Tuesday goes big – Sophos News
(It should be noted that one issue patched in June, CVE-2024-38213, is under active attack in the wild – a good argument for applying patches as soon as possible after release.) Microsoft also took pains this month to flag three other CVEs for which fixes have already gone out, but that are included in Patch Tuesday information for transparency’s sake; we list those in Appendix D as well. However, with over two dozen advisories, a number of “informational” notices concerning material released in June and July, two high-profile issues for which the fixes are still a work in progress, and over 85 Linux-related CVEs covered in the release, administrators may find their patch prioritization especially complex this month.
