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.
