| Total CVEs Patched | 63 |
| Zero-Day Vulnerabilities | 1 |
| Actively Exploited | 1 |
| Critical Severity | 5 |
| Important Severity | 58 |
| Moderate/Low Severity | 0 |
Severity: Important (CVSS 7.0)
Status: Actively Exploited in the Wild
Attack Vector: Local
Authentication Required: Yes (Low-Privileged User)
The Threat:
CVE-2025-62215 is a Windows Kernel elevation of privilege vulnerability with a CVSS score of 7.0 that is being actively exploited in the wild as a zero-day. The vulnerability involves a race condition in Windows Kernel where improper synchronization when accessing shared resources allows an authorized attacker to elevate privileges locally.
Technical Details:
The race condition is notable because it indicates this particular race condition is more reliable than others, making exploitation more predictable for attackers. This race condition flaw enables an authorized local attacker to escalate privileges by exploiting improper synchronization in shared resources.
Why This Matters:
An attacker who has already gained initial access to a system can leverage this vulnerability to gain SYSTEM-level privileges, achieving complete control over the compromised machine. Bugs like these are often paired with a code execution bug by malware to completely take over a system.
Attack Scenario:
Mitigation Priority: CRITICAL - Deploy within 24-48 hours
Severity: Critical (CVSS 9.8)
Attack Vector: Network (Remote)
Authentication: None Required
Exploitation Assessment: Less Likely
The Threat:
CVE-2025-60724 is a remote code execution vulnerability affecting the Windows Graphics Device Interface (GDI) with a CVSS score of 9.8, involving a heap-based buffer overflow in the Microsoft Graphics Component.
Technical Details:
A heap-based buffer overflow in Microsoft Graphics Component allows an unauthorized attacker to execute code over a network. The vulnerability can be triggered by convincing a victim to download and open a document that contains a specially crafted metafile.
Worst-Case Scenario:
An attacker could trigger this vulnerability on web services by uploading documents containing a specially crafted metafile without user interaction, potentially causing RCE or information disclosure on web services that are parsing documents.
Who's Affected:
Mitigation:
Severity: Critical (CVSS 7.8)
Attack Vector: Local (Requires User Interaction)
Exploitation Assessment: Less Likely
The Threat:
CVE-2025-62199 is a remote code execution vulnerability in Microsoft Office with a CVSS score of 7.8, involving a use-after-free flaw that allows an unauthenticated attacker to execute code locally on a vulnerable workstation.
Attack Vector:
An attacker could exploit this flaw through social engineering by sending a malicious Microsoft Office document file to an intended target. The Preview Pane is an attack vector, which means exploitation does not require the target to open the file.
Why This Is Critical:
The Preview Pane attack vector is particularly dangerous because users don't need to explicitly open a malicious document—simply previewing it in Outlook or File Explorer can trigger exploitation.
Attack Scenario:
Additional Office RCE Vulnerabilities:
Mitigation:
Severity: Critical (CVSS 8.1)
Attack Vector: Network
Authentication: None Required
The Threat:
CVE-2025-30398 is an information disclosure vulnerability in Nuance PowerScribe 360 with a CVSS score of 8.1, where missing authorization allows an unauthorized attacker to disclose information over a network.
Technical Details:
An unauthenticated attacker could exploit this vulnerability by making an API call to a specific endpoint. The attacker could then use the data to gain access to sensitive information, including PII data, on the server.
Impact:
Healthcare organizations using Nuance PowerScribe 360 for medical transcription and reporting face potential exposure of:
Who's Affected:

November 2025 Patch Tuesday presents significant security challenges with 63 vulnerabilities requiring attention, headlined by an actively exploited Windows Kernel zero-day. The combination of critical RCE flaws in widely-used components like Microsoft Graphics and Office applications, alongside high-priority elevation of privilege vulnerabilities, demands swift and comprehensive patching efforts.
Key Priorities:
This marks a critical juncture as the first Patch Tuesday following Windows 10's end-of-life. Organizations still running Windows 10 without ESU now face exponentially increasing risk with each passing month. The actively exploited zero-day underscores that attackers continue to target Windows kernel vulnerabilities, making timely patching not just a best practice but a critical business imperative.
The Bottom Line: Don't delay November 2025 patching. The presence of an actively exploited zero-day means attackers are already weaponizing these vulnerabilities. Every unpatched system is a potential entry point for compromise.
