Microsoft released its November Patch Tuesday updates, addressing 63 vulnerabilities, including five critical and 58 important flaws. While this marks a 62% drop from last month’s 167 CVEs, the release still includes several notable fixes for Windows users and enterprises.
Elevation of privilege (EoP) vulnerabilities were the most common, accounting for 46% of the patched issues, followed by remote code execution (RCE) vulnerabilities at 25.4%.
According to Satnam Narang, Senior Staff Research Engineer at Tenable, the November release is particularly significant despite the lower overall number of patched flaws. “This month, only one zero-day vulnerability was patched as part of Patch Tuesday. CVE-2025-62215 is an elevation of privilege flaw in the Windows Kernel,” Narang said. “Although exploitation requires a race condition, Microsoft confirmed it was exploited in the wild. This type of flaw is typically used as part of post-exploitation activity, following initial access through methods like phishing or other vulnerabilities.” This CVE is one of 11 privilege escalation bugs patched in the Windows Kernel in 2025.
The update also addressed CVE-2025-62222, a remote code execution vulnerability in the Microsoft Visual Studio Code CoPilot Chat Extension. Rooted in a command injection flaw, it could allow attackers to execute arbitrary code. Narang noted that while exploitation is less likely, it highlights the growing interest in discovering vulnerabilities in AI-assisted coding tools and generative AI systems, including large language models and code-editing extensions.
Even with fewer CVEs this month, the November Patch Tuesday demonstrates Microsoft’s ongoing efforts to secure Windows and related software, particularly in areas where attackers could escalate privileges or exploit AI tools for code execution.
