Microsoft's November 2025 Patch Tuesday updates addressed 63 vulnerabilities across various products, including Windows, Office, and Microsoft Edge. Among these, there’s a significant zero-day flaw in the Windows kernel, tracked as CVE-2025-62215, which has been actively exploited. This vulnerability allows attackers to elevate their privileges on affected systems by exploiting a race condition in the kernel. The CVSS score for this vulnerability is 7, indicating a serious risk, as successful exploitation could grant attackers SYSTEM privileges. The updates also included an Office vulnerability, CVE-2025-62199, which is a use-after-free issue that could enable unauthorized remote code execution. Microsoft's advisory emphasized that none of the vulnerabilities were publicly known prior to this release. This month saw a notable decrease in the number of addressed vulnerabilities—down from 177 in October—likely influenced by the cessation of updates for Windows 10. Observers are curious to see if the trend continues into December and how it compares to past records of vulnerabilities.
