Local privilege escalation in the Windows Internal System User Profile component allows an already-authenticated attacker to gain elevated (SYSTEM-level) privileges by triggering a use-after-free memory corruption condition (CWE-416). The flaw affects Windows 10 (21H2/22H2), Windows 11 (24H2/25H2/26H1), and Windows Server 2025 including Server Core. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the CVSS 7.8 rating and full high impact on confidentiality, integrity, and availability make it a meaningful patch-cycle priority.

Local privilege escalation in the Microsoft Windows USB driver stack lets an already-authenticated low-privileged user win a race condition (CWE-362) to gain SYSTEM-level control across Windows 10 (1607-22H2), Windows 11 (24H2/25H2/26H1), and Windows Server 2012 through 2025. Reported by Microsoft with a patch available; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. EPSS is low (0.19%, 9th percentile) and SSVC rates exploitation as none but technical impact as total, indicating high damage potential if a working exploit is developed.

Local code execution in Microsoft Windows arises from a heap-based buffer overflow in a Windows Data DLL, letting an attacker who can get a victim to open crafted content run arbitrary code with the victim's privileges. Affected builds span Windows 10 (1607 through 22H2), Windows 11 (24H2, 25H2, 26H1), and Windows Server 2012 through 2025. Microsoft (the reporter) has released a patch; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Remote code execution in the Microsoft Windows DHCP Server role allows an unauthenticated, adjacent-network attacker to run arbitrary code by triggering a heap-based buffer overflow (CWE-122) in DHCP message parsing. Affected systems span Windows Server 2012 through Windows Server 2025 (including Server Core installations) plus the DHCP service on Windows 10 versions 1607 and 1809, with full confidentiality, integrity, and availability impact. Microsoft has released a patch; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Local privilege escalation in Windows Kernel-Mode Drivers on Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025 lets an authenticated local attacker corrupt kernel memory via a use-after-free and gain SYSTEM-level control. Rated CVSS 7.0 (Important) and reported by Microsoft itself; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. The high attack complexity (AC:H) reflects the race-condition nature typical of kernel UAF bugs, which tempers real-world exploitability despite full C/I/A impact.

Local privilege escalation in the Microsoft Install Service (Windows Installer) affects supported Windows 10, Windows 11, and Windows Server 2019-2025 builds, letting an already-authenticated local user with limited rights (PR:L) elevate to SYSTEM. The flaw stems from improper privilege management (CWE-269) in how the service handles operations, yielding full confidentiality, integrity, and availability impact. Microsoft has released a patch; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.

Local privilege escalation in the Windows Application Model (the subsystem underlying UWP/packaged app lifecycle and activation) lets an authorized attacker with an existing low-privileged foothold gain SYSTEM-level control by triggering a use-after-free memory-corruption condition. All supported Windows client and server builds from Windows 10 1607 through Windows 11 26H1 and Windows Server 2016 through Server 2025 are affected. This is a Microsoft-reported flaw with a vendor patch available; there is no public exploit identified at time of analysis and it is not on CISA KEV.

Local privilege escalation in the Microsoft Windows Resilient File System (ReFS) driver allows an authenticated attacker to run code with SYSTEM-level privileges by triggering a heap-based buffer overflow. The flaw (CVSS 7.8) affects a broad range of Windows 10, Windows 11, and Windows Server 2016-2025 builds and carries high confidentiality, integrity, and availability impact. It is a Microsoft-reported issue with a vendor patch available, and there is no public exploit identified at time of analysis.

Buffer over-read in Windows NTFS allows an authorized attacker to disclose information locally.

Local code execution in the Windows Media component of Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025 allows an authenticated local attacker to run arbitrary code by triggering a heap-based buffer overflow. Successful exploitation yields high confidentiality, integrity, and availability impact within the current security context, and Microsoft has released a patch. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.

Remote code execution in Microsoft Windows GDI+ (gdiplus) lets an unauthenticated network attacker run arbitrary code when a victim opens or renders a specially crafted image, via a heap-based buffer overflow (CWE-122). The flaw affects a broad range of supported Windows client and server builds (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025). It carries a critical CVSS 9.6 with a scope-changed impact, but requires user interaction and currently has no public exploit identified at time of analysis.
