Microsoft discloses multiple Windows elevation-of-privilege flaws across kernel and core components

Microsoft published security advisories for a series of Windows elevation-of-privilege vulnerabilities affecting the Windows Kernel, File Explorer, Windows Management Service, Windows UI XAML Phone DatePickerFlyout, Windows Graphics Component, Windows Storage, and the DirectX Graphics Kernel. The referenced flaws include CVE-2026-26132, CVE-2025-62565, CVE-2025-54103, CVE-2025-54111, CVE-2025-55693, CVE-2024-38249, CVE-2025-62573, CVE-2024-38248, and CVE-2025-55678.

The disclosures indicate a broad patching effort spanning core operating system subsystems and user-facing Windows components, with repeated exposure in privileged areas such as the kernel and graphics stack. For defenders, the concentration of elevation-of-privilege issues across these components raises the risk that attackers could chain local access or code execution with privilege escalation to gain SYSTEM-level or otherwise expanded rights on affected Windows systems, making prompt validation and deployment of Microsoft updates a priority.
