Local privilege escalation in the Windows Kernel lets an already-authenticated, low-privileged user corrupt kernel memory via a use-after-free (CWE-416) and gain higher privileges on the host. The flaw affects a broad range of currently-supported Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2016 through 2025); Microsoft has shipped a fix. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Integer overflow or wraparound in Windows Spaceport.sys allows an unauthorized attacker to elevate privileges with a physical attack.

Local privilege escalation in the Windows Audio Compression Manager (ACM) allows a low-privileged authenticated user to elevate to higher privileges (CVSS 7.8, CWE-284 improper access control). It affects a broad Windows fleet spanning Windows 10 (1607 through 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.

Local privilege escalation in Microsoft Windows Resilient File System (ReFS) allows an authenticated low-privileged user to gain elevated (SYSTEM-level) privileges by triggering a stack-based buffer overflow (CWE-121) in the ReFS driver. The flaw affects a broad range of Windows client and server releases, from Windows 10 1607 through Windows 11 26H1 and Windows Server 2016 through 2025. 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 AppX Deployment Service (AppXSvc) lets an already-authenticated, low-privileged user win a race condition to elevate to higher privileges across a broad range of Windows client and server builds (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025). The flaw stems from improper synchronization of a shared resource, and successful exploitation yields full confidentiality, integrity, and availability impact on the host. It is reported by Microsoft with a vendor patch available; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Local privilege escalation in the Windows Win32K kernel-mode subsystem allows an already-authenticated low-privileged user to elevate to SYSTEM through an improper access-control flaw. The issue affects a broad range of Windows client and server releases, from Windows 10 1607 and Windows Server 2012 through Windows 11 26H1 and Windows Server 2025. Microsoft has released a patch; there is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.

Use of uninitialized resource in Windows SMB allows an authorized attacker to disclose information locally.

Local privilege escalation in the Windows Spaceport.sys Storage Spaces driver lets an already-authenticated low-privileged user gain SYSTEM-level control across Windows 10, Windows 11, and Windows Server 2016 through 2025. The flaw stems from a missing authentication check on a critical driver function (CWE-306), and Microsoft has released a patch; no public exploit has been identified at time of analysis. With CVSS 7.8 (local, low-privilege) and full confidentiality, integrity, and availability impact, it is a strong candidate for chaining after an initial foothold.

Exposure of sensitive system information to an unauthorized control sphere in Windows Kernel allows an unauthorized attacker to disclose information locally.

Heap-based buffer overflow in Windows USB Video Driver allows an unauthorized attacker to elevate privileges with a physical attack.

Elevation of privilege in Microsoft Windows (Server 2012 through 2025 and Windows 10/11 clients) lets a low-privileged local user gain SYSTEM-level rights by abusing an improper access control (CWE-284) weakness. The flaw was reported by Microsoft with a patch available, and CVSS 3.1 rates it 7.8 (High) with local vector and low privileges required. No public exploit identified at time of analysis and it is not listed in CISA KEV, so this is a patch-worthy but not emergency issue absent evidence of active exploitation.

Local code execution in the Microsoft Windows NTFS file-system driver lets an attacker run arbitrary code by inducing a victim to interact with a specially crafted NTFS artifact (e.g., a malicious volume, VHD, or file). The flaw stems from an integer underflow (CWE-191) and spans a broad range of Windows client and server builds from Windows Server 2012 through Windows Server 2025 and Windows 10/11. Microsoft has released a patch; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
