The CVSS 3.1 score is 7.0 (High) with a local vector and high attack complexity, and there is no public exploit identified at time of analysis. Microsoft self-reported the issue and has released a patch through the MSRC update guide.

Remote code execution in the Microsoft Windows Message Queuing (MSMQ) service arises from a use-after-free (CWE-416) memory-corruption flaw that an authenticated attacker can trigger across a network to run arbitrary code in the service context. It affects a broad range of supported Windows client and server releases from Windows 10 1607 and Windows Server 2012 through Windows 11 26H1 and Windows Server 2025 wherever the MSMQ component is enabled. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Microsoft rates it CVSS 7.5 and has released a fix.

Elevation of privilege in the Microsoft Windows Universal Disk Format File System driver (UDFS) allows a local attacker to gain higher privileges after a user mounts or opens a maliciously crafted UDF-formatted volume such as an ISO or disc image. The flaw is an out-of-bounds read (CWE-125) in the kernel-mode UDFS parser, and successful exploitation yields high impact to confidentiality, integrity, and availability (CVSS 7.8). No public exploit identified at time of analysis and it is not listed in CISA KEV, but Microsoft has released a patch.

Local privilege escalation in the Windows Installer (msiexec) service across Windows 10, Windows 11, and Windows Server 2012 through 2025 allows an already-authenticated local user to gain higher privileges by triggering a use-after-free memory-corruption condition. No public exploit has been identified at time of analysis, and it is not listed in CISA KEV, but Microsoft has published a patch. The high CVSS complexity (AC:H) indicates exploitation requires winning a race or meeting specific timing/heap conditions rather than being trivially reliable.

Local privilege escalation to code execution in the Windows NTFS file-system driver stems from a heap-based buffer overflow (CWE-122) that an authenticated local attacker can trigger to run arbitrary code with elevated privileges. The flaw was reported by Microsoft and spans a broad range of currently-supported Windows client and server releases, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and reliable memory-corruption primitive in a core kernel-mode driver make it a strong candidate for patch-Tuesday prioritization.

Local privilege escalation in the Windows Win32K kernel subsystem (CWE-122 heap-based buffer overflow) lets an already-authenticated low-privileged attacker corrupt kernel heap memory and gain SYSTEM-level control across a broad range of Windows client and server releases. The flaw carries a CVSS 3.1 base score of 8.8 with a changed scope (S:C), reflecting that a user-mode process can compromise the kernel security boundary. It was reported by Microsoft, a vendor patch is available, and there is no public exploit identified at time of analysis.

Privilege escalation in the Windows Netlogon service allows an already-authenticated, low-privileged network attacker to elevate to higher privileges by exploiting a use-after-free (CWE-416) memory-corruption condition. The flaw 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, including Server Core installations.

Denial of service in Windows Hyper-V allows an authorized, adjacent-network attacker to crash or disrupt the hypervisor by triggering a buffer over-read (CWE-126). Affected platforms span Windows 10, Windows 11, and Windows Server 2012 through 2025, covering a broad slice of Microsoft's enterprise footprint. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but a vendor-issued patch is available via Microsoft MSRC.

Remote code execution in the Microsoft Windows Event Logging Service allows an authenticated attacker with low privileges to execute code over a network after enticing a user into an interaction (UI:R), due to insufficient granularity of access control (CWE-1220). The flaw affects a broad range of Windows client and server builds 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 CVE is not listed in CISA KEV.

Local privilege-level code execution in the Windows NTFS file-system driver affects a broad range of Windows client and server releases, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. A heap-based buffer overflow (CWE-122) lets an authorized local attacker who can induce a user to interact with a crafted file or volume execute arbitrary code in the security context of the kernel-mode NTFS component. There is no public exploit identified at time of analysis and it is not in CISA KEV, but Microsoft has released a patch and the flaw carries full high confidentiality, integrity, and availability impact.

Local privilege escalation in the Windows Web Proxy Auto-Discovery (WPAD) service affects Windows 10 Version 1607 and Windows Server 2012, 2012 R2, and 2016 (including Server Core installations), where a heap-based buffer overflow (CWE-122) lets an authenticated local attacker corrupt kernel/service heap memory and elevate to higher privileges. Microsoft has released a patch and reported the flaw itself; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. The CVSS 3.1 base score is 7.8 (AV:L/AC:L/PR:L/UI:N) reflecting a high-impact but locally-scoped attack requiring existing low-privilege access.

Local privilege escalation in the Microsoft Windows Kernel lets an already-authenticated attacker corrupt heap memory (CWE-122) to run code with SYSTEM-level privileges. It affects a broad range of supported Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through Server 2025). No public exploit identified at time of analysis, but the CVSS 8.8 rating and scope change make it a strong candidate for chaining after initial access.

Information disclosure in the Windows Network Policy Server (NPS) SNMP component allows a remote, unauthenticated attacker to read out-of-bounds memory over the network and disclose sensitive process data. The flaw 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. It was reported by Microsoft, a vendor patch is available, and no public exploit has been identified at time of analysis (not listed in CISA KEV).

Remote information disclosure in the Microsoft Windows Kernel (CWE-125 out-of-bounds read) lets an unauthenticated attacker read kernel memory over a network, per the CVSS AV:N/PR:N vector, affecting a broad range of Windows 10, Windows 11, and Windows Server 2016 through 2025 builds. The flaw carries high confidentiality impact (C:H) with a minor availability side effect and no integrity impact, scoring CVSS 8.2. No public exploit is identified at time of analysis and it is not in CISA KEV, but the network-reachable, no-authentication, no-interaction profile makes it a notable patch priority.

Local privilege escalation in Microsoft Windows (Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through 2025) arises from a use-after-free memory-corruption flaw (CWE-416) that lets an already-authenticated local user run code at elevated privilege. The CVSS 3.1 base score is 7.8 with a scope-changed vector, and Microsoft has shipped a fix via MSRC. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, so exploitation is currently theoretical rather than observed.
