This update is mandatory as it bundles the September 2025 Patch Tuesday security fixes, addressing two publicly disclosed zero-days and 81 additional vulnerabilities. Systems will update to build 19045.6332 (22H2) or 19044.6332 (21H2) and can be installed via Windows Update or the Microsoft Update Catalog. Microsoft reports no known issues with this release.

🔒 Microsoft released its September 2025 Patch Tuesday addressing 81 vulnerabilities, including two publicly disclosed zero-days affecting Windows SMB Server and the Newtonsoft.Json library bundled with SQL Server. The update bundle contains nine Critical fixes — five remote code execution issues — and a total of 41 elevation-of-privilege vulnerabilities across Windows, Azure, and related components. Administrators are advised to apply patches promptly, enable and test SMB Server signing and Extended Protection for Authentication, enable auditing to check compatibility, and ensure SQL Server receives the patched Newtonsoft.Json to mitigate the disclosed flaws.

🔒 Microsoft has released cumulative updates KB5065426 (24H2) and KB5065431 (23H2) as the September 2025 Patch Tuesday rollup; these mandatory updates address security vulnerabilities and multiple reliability and UX issues. Install via Start > Settings > Windows Update or download from the Microsoft Update Catalog; Enterprise/Hotpatch systems receive KB5065474 reporting build 26100.6508. After updating, 24H2 moves to build 26100.6584 and 23H2 to build 226x1.5909, and Microsoft warns that support for 23H2 ends on November 11, 2025.

🔔 Microsoft’s September 2025 update addresses 84 vulnerabilities, including two publicly disclosed zero-days and eight Critical issues. CrowdStrike’s analysis identifies elevation of privilege, remote code execution and information disclosure as the top exploitation vectors and notes many critical flaws require some user interaction. Key affected components include Windows, Extended Security Updates (ESU) and Microsoft Office, with notable CVEs in SMB, NTLM, Hyper-V and graphics subsystems. Organizations should prioritize patching, apply mitigations for unpatchable issues, and plan for Windows 10 end of support in October 2025.

⚠️ Microsoft says the August 2025 security updates are causing unexpected User Account Control (UAC) credential prompts and preventing application installations and MSI repair operations for non‑admin users across supported Windows client and server releases. The behavior stems from a patch addressing CVE-2025-50173, a Windows Installer privilege escalation vulnerability that now enforces elevated UAC prompts during MSI repair and related operations. Affected scenarios include MSI repair commands, ConfigMgr deployments relying on per‑user advertising, Secure Desktop enablement, and launching certain Autodesk applications. Microsoft plans a fix allowing admins to exempt specific apps and recommends running affected apps as administrator or applying a Known Issue Rollback via support as a temporary mitigation.

🔧 Microsoft published the optional KB5064081 preview cumulative update for Windows 11 24H2, moving affected systems to build 26100.5074 and rolling out thirty-six new features and fixes. The update standardizes CPU reporting in Task Manager so the Processes tab now uses the same calculation as Performance and Users: (Δ Process CPU Time) ÷ (Δ Elapsed Time × Logical Processors), making metrics consistent and aligning them with third‑party monitors. Users who want the legacy view can enable an optional CPU Utility column in the Details tab. The release also bundles UI, File Explorer, Taskbar, Windows Hello, backup, and numerous bug fixes, while Microsoft lists two known issues (CertEnroll errors and NDI streaming lag).

⚠️ Delta Electronics disclosed an CNCSoft-G2 out‑of‑bounds write vulnerability (CVE-2025-47728) in DPAX file parsing that can cause memory corruption and enable arbitrary code execution in the affected process. CISA assigns a CVSS v4 base score of 8.5 and notes low attack complexity but requires user interaction such as opening a malicious file or visiting a malicious page. Affected versions include v2.1.0.20 and earlier; Delta recommends updating to v2.1.0.27 or later per advisory Delta-PCSA-2025-00007. CISA advises applying the update, isolating control systems, avoiding untrusted attachments, and following ICS recommended practices; no public exploitation has been reported to date.

🔒 Microsoft released fixes for more than 100 vulnerabilities in August 2025, including at least 13 rated Critical. Notable flaws include CVE-2025-53786, which lets attackers pivot from compromised on‑premises Exchange Server instances into cloud tenant services, and CVE-2025-53779 (BadSuccessor), a Kerberos dMSA weakness that can yield domain admin rights. Other high‑risk bugs affect GDI+, Word preview and NTLM; several fixes require configuration steps beyond patch installation.

⚠️ Microsoft released its August 2025 Patch Tuesday updates addressing 111 vulnerabilities, including 13 marked critical. The fixes span remote code execution, elevation-of-privilege and information-disclosure flaws across Windows, Hyper-V, Microsoft Office, GDI+ and cloud services. Microsoft reports no observed in-the-wild exploitation but notes several issues where exploitation is assessed as “more likely.” Talos is issuing Snort detection rules and urges administrators to apply vendor updates and intrusion-detection signatures promptly.

🛡️ Microsoft’s August 2025 Patch Tuesday addresses 107 CVEs, including one publicly disclosed Windows Kerberos zero‑day (CVE-2025-53779) and 13 Critical flaws. Notable fixes cover high‑severity RCEs in the Windows Graphics Component and GDI+ and an NTLM elevation‑of‑privilege issue. Microsoft has released patches; organizations should apply updates promptly and use Falcon Exposure Management to prioritize and visualize exposure.
