Microsoft has released patched builds and the SSVC assessment confirms no observed exploitation, with EPSS at 0.31% (22nd percentile) corroborating a low immediate threat posture; however, Print Spooler's historical exploitation history (PrintNightmare family) warrants prompt patching given attacker familiarity with the component.

Remote code execution in the Windows SMB Server Network Transport driver (srvnet.sys) allows unauthenticated network attackers to run arbitrary code by triggering a use-after-free condition, affecting a broad range of Windows client and server releases from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. Because the CVSS vector is AV:N/AC:L/PR:N/UI:N (9.8 Critical), exploitation needs no authentication or user interaction, giving this the structural profile of a wormable SMB flaw similar to prior srvnet.sys issues. No public exploit was identified at time of analysis and CISA SSVC lists exploitation as 'none', with a modest EPSS of 0.57% (43rd percentile).

Local privilege escalation in the Windows Win32k kernel-mode subsystem allows an authenticated low-privileged attacker to disclose sensitive kernel information and elevate to higher privileges on affected Windows 10, Windows 11, and Windows Server (2012 through 2025) systems. Microsoft has released patches; SSVC rates technical impact as total but exploitation status as none, and there is no public exploit identified at time of analysis. EPSS is low (0.50%, 39th percentile), consistent with a local-only, non-automatable flaw rather than mass-exploitable one.

Local privilege escalation in the Windows Network File System (NFS) component allows an authenticated attacker to elevate to SYSTEM by triggering a heap-based buffer overflow (CWE-122). Reported by Microsoft and affecting a broad range of Windows 10, Windows 11, and Windows Server 2012-2025 releases, with a vendor patch available via MSRC. No public exploit identified at time of analysis, and no CISA KEV listing.

Information disclosure in Windows File Explorer exposes sensitive memory contents to local attackers due to CWE-908 use of an uninitialized resource. Triggered when a local user interacts with File Explorer, the flaw allows memory contents - potentially including sensitive data from other processes or the OS - to be read without elevated privileges. No public exploit code has been identified and CISA has not listed this in KEV, but the breadth of affected platforms (Windows 10 through 11 and Windows Server 2012 through 2025) makes patching broadly applicable.

Uninitialized memory exposure in the Microsoft Windows Codecs Library enables a local attacker to disclose sensitive process memory contents on affected Windows systems. The flaw (CWE-908) requires user interaction - specifically opening or processing a specially crafted media file - but demands no elevated privileges. No public exploit code exists and no active exploitation is confirmed; EPSS sits at 0.51% (40th percentile), consistent with SSVC's 'Exploitation: none' assessment, making this a medium-severity, low-urgency issue relative to the breadth of affected platforms.

Remote code execution in Microsoft's Windows Network File System (NFS) server role affects a broad range of Windows client and server builds from Windows Server 2012 through Windows Server 2025 and Windows 10/11. An unauthenticated network attacker who wins a race condition in a shared NFS resource can execute arbitrary code on the target. There is no public exploit identified at time of analysis and CISA SSVC rates exploitation as none; EPSS is low at 0.64% (47th percentile), consistent with the high attack complexity of racing the vulnerable code path.

Elevation of privilege in the Windows Network File System (NFS) component affects a broad range of Microsoft platforms - Windows 10 (1607 through 22H2), Windows 11 (24H2, 25H2, 26H1), and Windows Server 2012 through 2025 - where an authorized attacker can win a time-of-check/time-of-use (TOCTOU) race condition over the network to gain higher privileges. The CVSS 3.1 vector (AV:N/AC:H/PR:L) indicates a network-reachable but high-complexity flaw requiring low-level existing privileges, with full high impact to confidentiality, integrity and availability. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; a Microsoft (MSRC) patch is available.

Privilege escalation via a heap-based buffer overflow in the Windows Network File System (NFS) role lets an authenticated, low-privileged network attacker send crafted requests to corrupt server heap memory and gain elevated privileges. Affected systems span Windows 10 (1607 through 22H2), Windows 11 (24H2/25H2/26H1), and Windows Server 2012 through 2025 wherever the Server for NFS role is present. No public exploit was identified at time of analysis and the flaw is not in CISA KEV, but the 8.8 CVSS with a network-reachable, low-complexity, no-user-interaction profile makes it a meaningful patch priority on NFS hosts.

Local code execution in Microsoft Windows Media Foundation stems from a heap-based buffer overflow (CWE-122) that lets an attacker run arbitrary code in the context of the exploiting process across 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 rates it CVSS 8.4 (AV:L) with total confidentiality, integrity, and availability impact.

Per the CVSS vector an unauthenticated attacker with local access can achieve high-impact code execution with no user interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; Microsoft has released a patch through the MSRC update guide.

Uninitialized memory disclosure in the Windows SMB stack allows a locally authenticated attacker to read sensitive contents from uninitialized buffers, affecting Windows 10, Windows 11, and Windows Server 2012 through 2025. The flaw (CWE-908) resides in the SMB subsystem where a resource is consumed before being properly zeroed, leaking residual memory contents to a low-privileged local user. No public exploit code exists and the vulnerability is not listed in the CISA KEV catalog; SSVC assessment places exploitation at none with partial technical impact, making this a standard patch-cycle priority rather than an emergency response item.

Privilege escalation in Microsoft Windows DHCP Server (across Windows Server 2012 through 2025 and Windows 10 1607/1809) allows an authenticated attacker on an adjacent network to elevate privileges by triggering a heap-based buffer overflow (CWE-122). Exploitation yields full confidentiality, integrity, and availability impact (C:H/I:H/A:H) on the affected server, effectively giving the attacker high-privilege control of the DHCP service host. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.

Remote code execution in the Microsoft Windows DHCP Server role (Windows Server 2012 through 2025, plus Windows 10 1607/1809) arises from a double-free (CWE-415) condition that an authorized, network-adjacent attacker can trigger to run arbitrary code in the DHCP service context. The CVSS 3.1 vector (AV:N/AC:H/PR:L/UI:N) indicates a network-reachable but high-complexity attack requiring low-level privileges, with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and no CISA KEV listing, so exploitation appears theoretical rather than active for now.

Privilege escalation in Microsoft Active Directory Certificate Services (AD CS) allows an authenticated network attacker to elevate privileges due to improper authorization (CWE-285) in certificate request/enrollment handling across Windows Server 2012 through 2025 and their Server Core installations. With a CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N) and full high impact to confidentiality, integrity, and availability, a low-privileged domain user can abuse AD CS authorization checks to gain elevated rights, potentially up to domain compromise. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but AD CS abuse (ESC-class attacks) is a well-established, high-value target class.

Local privilege escalation in the Microsoft Windows Kernel allows an authenticated attacker to gain SYSTEM-level control by exploiting a use-after-free (CWE-416) memory corruption condition. The flaw affects a broad range of Windows client and server builds - from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025 - and was 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; the CVSS 3.1 base score is 7.8 (AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H).

Cross-site scripting in Active Directory Federation Services (AD FS) on Windows Server 2012 through 2025 enables an authorized, high-privileged attacker to inject malicious scripts into AD FS web pages, producing spoofing effects against users who interact with the affected portal. The CVSS vector (PR:H, UI:R, S:C) confirms this is a post-compromise capability requiring admin-level access and victim interaction, not an unauthenticated initial access vector. No active exploitation is confirmed - SSVC rates exploitation as 'none', EPSS sits at 0.38% (30th percentile), and the vulnerability is absent from CISA KEV - placing this firmly in the low-urgency category despite network reachability of the AD FS web interface.

Local privilege escalation in Windows Active Directory across a broad range of Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025) allows an authenticated local attacker to elevate privileges by triggering an integer overflow (CWE-190).

Local privilege escalation in the Windows Telephony Service (TAPI) affects a broad range of Microsoft Windows client and server releases, from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025. A local, low-privileged attacker who wins a race condition (CWE-362) in the service's handling of a shared resource can corrupt state and elevate to higher privileges, gaining full confidentiality, integrity, and availability impact on the host. There is no public exploit identified at time of analysis and it is not on CISA KEV; EPSS was not provided.

Local privilege escalation in the Windows NTFS file system driver lets an authenticated low-privileged user win a race condition (CWE-362) to gain SYSTEM-level rights across nearly all supported Windows client and server builds, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. Microsoft has shipped fixes and publicly available exploit code exists, though EPSS rates near-term mass exploitation modestly at 2.16% (80th percentile) and CISA's SSVC framework records no observed exploitation, indicating opportunistic rather than widespread abuse. The high AC:H reflects the timing-dependent nature of the flaw, which reduces reliability but does not eliminate risk on multi-user or shared hosts.

Denial of service in Microsoft Active Directory Federation Services (AD FS) allows an unauthenticated, remote attacker to send crafted network requests that drive a request-handling routine into an infinite loop (CWE-835), exhausting CPU and rendering the federation service unavailable. All supported Windows Server releases hosting the AD FS role are impacted, and because the flaw requires no authentication and no user interaction (CVSS 7.5, AV:N/AC:L/PR:N/UI:N), it can knock out single sign-on for every relying-party application. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so this is a patch-priority availability issue rather than a confirmed active-exploitation event.

Remote code execution in the Microsoft Windows DHCP Server role allows an unauthenticated network attacker to run arbitrary code by triggering a heap-based buffer overflow (CWE-122) in the service's packet handling. The flaw carries a critical CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) and affects Windows Server 2012 through 2025 as well as the underlying Windows 10 1607/1809 code base. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but the unauthenticated network RCE profile makes it a high-priority patch.

The flaw affects a broad span of supported Windows client and server releases from Windows Server 2012 through Windows 11 26H1 and Windows Server 2025. There is no public exploit identified at time of analysis, EPSS risk is modest (0.64%), and CISA's SSVC framework marks exploitation as 'none' — a patch is available from Microsoft.

Information disclosure in the Windows Network Policy Server (NPS) SNMP handling allows a remote, unauthenticated attacker to read out-of-bounds memory over the network and disclose potentially sensitive data. The flaw affects a broad range of Windows Server (2012 through 2025) and Windows client builds where the NPS role/SNMP component is present. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; a vendor patch is available from Microsoft (MSRC).

Information disclosure in Microsoft Windows Remote Desktop Protocol (RDP) lets a remote, unauthenticated attacker read out-of-bounds memory across a wide swath of Windows client and server builds (Windows 10 1607 through Windows 11 26H1, Windows Server 2012 through Server 2025). The root cause is an off-by-one error (CWE-193) that overreads adjacent memory, potentially leaking sensitive process data; CVSS is 7.5 with confidentiality-only impact and no code execution. There is no public exploit identified at time of analysis, and the low EPSS (0.89%) plus CISA SSVC exploitation status of 'none' indicate no observed exploitation yet.

Local privilege escalation in the Windows Code Integrity module (ci.dll) allows an already-authenticated, low-privileged user on affected Windows 10, Windows 11, and Windows Server builds to read memory outside intended bounds and gain SYSTEM-level control. Microsoft has shipped patches and rates real-world impact as total (full confidentiality, integrity, and availability loss on the host), but the flaw requires prior local access and there is no public exploit identified at time of analysis. EPSS is low (0.25%, 16th percentile) and CISA SSVC lists exploitation as none, indicating this is an important patch-cycle item rather than an emergency.

Remote code execution in the Microsoft Message Queuing (MSMQ) service across Windows 10, Windows 11 (through 26H1), and Windows Server 2012-2025 allows an authorized (PR:L) attacker to run arbitrary code over the network by triggering a use-after-free memory-corruption condition. Microsoft self-reported the flaw and has shipped fixed builds; SSVC rates exploitation as none and EPSS is low (0.48%, 38th percentile), so there is no public exploit identified at time of analysis despite the high 8.8 CVSSv3.1 base score.

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 Microsoft Windows Installer (MSI) service affects a broad range of Windows client and server releases, from Windows 10 1607 and Server 2012 through Windows 11 25H2/26H1 and Server 2025. A use-after-free (CWE-416) in the Windows Installer component lets a low-privileged authenticated attacker who already has local code execution corrupt memory to run code with elevated (SYSTEM-level) privileges. No public exploit identified at time of analysis and the SSVC exploitation status is 'none', but the technical impact is rated total and Microsoft has shipped a patch.

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 Microsoft Windows Win32K lets an authenticated low-privileged user corrupt kernel heap memory (CWE-122) to gain SYSTEM-level control across virtually all supported Windows client and server builds. Publicly available exploit code exists, though CISA SSVC assessed exploitation status as none and EPSS is modest (0.37%, 29th percentile), indicating a serious but not yet mass-exploited weakness. A vendor patch is available via Microsoft's update guide, making prompt patching the clear priority.

Affected platforms span Windows 10 (1607 through 22H2), Windows 11 (24H2, 25H2, 26H1), and Windows Server 2012 through 2025. Microsoft reported the flaw and has shipped a patch; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Local information disclosure in Windows Universal Plug and Play (upnp.dll) exposes sensitive memory contents to authorized low-privilege users across a wide range of Windows 10, Windows 11, and Windows Server releases. The flaw stems from use of an uninitialized resource (CWE-908), meaning the UPnP service reads from memory that has not been properly initialized before use, potentially leaking stale heap or stack contents. No active exploitation has been confirmed and no public exploit code has been identified at time of analysis; a vendor patch is available via the Microsoft Security Response Center.

Local privilege escalation in the Windows Routing and Remote Access Service (RRAS) lets an already-authenticated, low-privileged user gain SYSTEM-level control across a broad range of Windows 10, Windows 11, and Windows Server 2012 through 2025 builds. The root cause is a missing authentication check on a critical RRAS function (CWE-306), enabling an authorized attacker to bypass expected authorization and fully compromise confidentiality, integrity, and availability of the host. There is no public exploit identified at time of analysis, EPSS probability is low (0.22%), and CISA SSVC rates current exploitation as none, but the total technical impact and Microsoft-supplied patch make prompt patching worthwhile.

Local privilege escalation in the Windows NTFS file-system driver lets an already-authenticated low-privileged user read memory outside allocated bounds (CWE-125) to gain elevated privileges. 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; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Remote code execution in the Windows DNS Server component allows an authorized, high-privileged attacker on an adjacent network to traverse outside intended directory boundaries and execute arbitrary code on the target host. Affected platforms span Windows Server 2012 through Server 2025 and Windows 10 versions 1607 and 1809. No public exploit code exists and no active exploitation has been confirmed - CISA SSVC classifies exploitation as 'none' and EPSS sits at 0.37% (29th percentile) - however SSVC rates technical impact as 'total', consistent with the full C:H/I:H/A:H CVSS triad.

Elevation of privilege in the Microsoft Windows RPC API lets an unauthenticated attacker on an adjacent network gain higher privileges by exploiting an improper authentication weakness (CWE-287), provided a user is lured into an interaction. The flaw spans a broad range of client and server builds from Windows Server 2012 through Windows Server 2025 and Windows 10 1607 through Windows 11 26H1. No public exploit identified at time of analysis; the issue was reported by Microsoft, which has released a fix.
