Security teams are bracing for September 2025’s Patch Tuesday releases, anticipating fixes for ongoing issues stemming from the August updates, particularly those affecting Windows operating systems. The continuous stream of vulnerabilities and the need for rapid patching underscore the critical importance of a robust patch management program in today’s threat landscape.
The recent spate of problems following Microsoft’s August Patch Tuesday – including failures in recovery operations, update installations, and compatibility issues with streaming software and Microsoft Teams – highlights the inherent risks of software updates. Organizations,regardless of their cybersecurity insurance status,must prioritize efficient patch deployment to mitigate potential exploits and maintain a strong security posture. the future of the CVE management system itself remains uncertain, dependent on continued funding for MITRE and NIST.
Recent Windows Update Issues Demand Attention
microsoft responded to several problems triggered by the August Patch Tuesday security releases with a series of out-of-band updates. Initial responses focused on resolving failures in reset and recovery operations for both Windows 10 and 11. Specifically, KBs KB5063877, KB5063709, and KB5063875 where released for Windows 10 and older Windows 11 versions, respectively, and should be applied in place of the original August updates.
Further complications arose with Windows update failures when installing updates from network shares using the Windows Update Standalone Installer (WUSA). Microsoft is addressing this issue,impacting Windows 11 24H2 and Server 2025,through Known Issue rollback (KIR). Additionally, the August 2025 security updates caused severe issues with NDI streaming software on some Windows 10 and 11 systems, with a resolution still under growth.A fix is also being rolled out for couldn’t connect
errors affecting the Microsoft Teams desktop and web applications.
September 2025 Patch Tuesday Predictions
This month’s Patch Tuesday is expected to deliver fixes addressing the previously mentioned issues with recovery operations, WUSA, streaming, and Microsoft Teams. Routine OS,Office,and SharePoint patches are also anticipated. A security update for the .NET framework, which hasn’t been seen recently, may also be included.
| Vendor | Expected Updates |
|---|---|
| Microsoft | OS, Office, SharePoint, .NET (potential) |
| Adobe | Creative Cloud, Acrobat (potential) |
| Apple | zero-day updates (deployment verification) |
| Chrome | |
| Mozilla | Firefox, Thunderbird |
Adobe released significant Creative Cloud updates last month, suggesting several app updates are likely. an Acrobat release is also possible next week. Apple’s august 20th release addressed several zero-day vulnerabilities; ensuring these updates are deployed remains crucial. Google typically releases Chrome updates with each Patch Tuesday, often late in the day. Mozilla released High-rated security updates for its entire product set on August 19th,and a new set is expected next week.
Did You Know? …
The CVE (Common Vulnerabilities and Exposures) matrix is a standardized naming system for publicly known cybersecurity vulnerabilities, used across vulnerability scanners, patch management systems, and software development tools.
Pro Tip: …
Prioritize patching based on the severity of the CVE and the potential impact to your organization. Regularly review vulnerability scan reports and adjust your patching schedule accordingly.
The patch process is fundamentally tied to the CVE matrix, influencing nearly every aspect of cybersecurity, from vulnerability scanning to software development and reporting.
Background on the CVE System
The CVE system,managed by MITRE corporation and funded by the Cybersecurity and Infrastructure Security Agency (CISA),provides a standardized way to identify and catalog publicly known cybersecurity vulnerabilities. Each vulnerability receives a unique CVE ID, allowing security professionals to track and address threats effectively.The system relies on a collaborative effort from researchers, vendors, and security communities worldwide.
