Remote denial of service in the Windows TCP/IP stack lets an unauthorized adjacent-network attacker crash affected systems by triggering a NULL pointer dereference (CWE-476) via crafted network traffic. Reported by Microsoft and patched across the Windows 10, Windows 11, and Windows Server 2012-2025 families, the flaw requires no authentication or user interaction but is limited to attackers on the same logical network segment. EPSS is low (0.14%, 34th percentile) and CISA SSVC lists exploitation as none, so this is a real-but-not-urgent patch item with no public exploit identified at time of analysis.
Local privilege escalation in the Win32K GRFX (graphics) subsystem of Microsoft Windows allows an authenticated, low-privileged user to execute arbitrary code in the kernel context via a heap-based buffer overflow. All currently supported Windows client and server releases (Windows 10 1607 through Windows 11 26H1, Windows Server 2012 through 2025) are affected. There is no public exploit identified at time of analysis, and EPSS probability is very low (0.02%), but the total technical impact and low exploitation barrier make it a meaningful patch-priority for endpoint hardening.
Local privilege escalation in Microsoft Windows Hyper-V (Windows 11 22H3/23H2 and Windows Server 2022) stems from a use-after-free memory corruption flaw that lets an attacker executing code in a guest context elevate privileges with a scope-changing impact on the host. Microsoft has released fixed builds and rates this critical (CVSS 9.3, total technical impact per CISA SSVC), but there is no public exploit identified at time of analysis and EPSS probability is very low (0.04%). The scope change (S:C) combined with the Hyper-V attack surface is consistent with a guest-to-host virtualization boundary escape.
Local denial of service in Microsoft Windows TCP/IP networking stack allows an unauthorized local attacker to trigger a null pointer dereference (CWE-476), crashing the system or causing broad service disruption. All supported Windows client and server releases from Windows Server 2012 through Windows 11 25H2/26H1 and Server 2025 are affected. Reported by Microsoft, this is a crash/availability issue only - no code execution or data exposure - with no public exploit identified at time of analysis and a very low (0.05%) EPSS exploitation probability.
Local privilege escalation in the Windows Remote Desktop component (CWE-122 heap-based buffer overflow) allows an authenticated low-privileged user to gain SYSTEM-level control across virtually all supported Windows client and server releases, from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through 2025. Microsoft has released patches; there is no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.04%), consistent with CISA SSVC rating exploitation as 'none'. The flaw is a serious defense-in-depth concern because it grants total confidentiality, integrity, and availability impact once a foothold exists, but it is not remotely reachable and requires prior local access.
Local privilege escalation in the Windows Common Log File System (CLFS) driver lets an already-authenticated low-privileged user gain SYSTEM-level rights on affected Windows client and server builds by triggering an integer underflow (CWE-191) in the driver's log-file parsing. The flaw yields total confidentiality, integrity, and availability impact on the local machine. There is no public exploit identified at time of analysis, EPSS risk is low (0.06%, 19th percentile), and CISA SSVC records exploitation status as none - but CLFS is a historically heavily-targeted attack surface, so patching is warranted.
Local privilege escalation in the Microsoft Windows Telephony Service (TAPI) lets an already-authenticated low-privileged user corrupt kernel/service memory via a use-after-free and gain elevated (typically SYSTEM-level) privileges across nearly all supported Windows client and server releases. Microsoft has released patches, and the flaw carries a total technical-impact rating (SSVC), though EPSS is very low (0.04%) and there is no public exploit identified at time of analysis. It is not on CISA KEV, indicating no confirmed active exploitation.
Local privilege escalation in the Windows Link-Layer Discovery Protocol (LLDP) component affects a broad range of Windows client and server builds, where a CWE-415 double-free condition can be leveraged by an already-authenticated low-privileged user to gain higher privileges. The flaw was reported by Microsoft and is addressed in the July 2026 servicing updates; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. EPSS is negligible (0.04%, 12th percentile), consistent with the high attack complexity (AC:H) and local-only vector.
Local privilege escalation in the Windows Projected File System (ProjFS) affects the full supported Windows line — Windows 10 (1809/21H2/22H2), Windows 11 (22H3 through 26H1), and Windows Server 2019/2022/2025 — where a use-after-free (CWE-416) lets an authenticated local user corrupt kernel/service memory and elevate to higher privileges. Microsoft-reported and patched, the flaw carries total technical impact per CISA SSVC but has no public exploit identified at time of analysis and a very low EPSS (0.04%). The high attack complexity (AV:L/AC:H) reflects a race-condition-style UAF that is non-trivial to win reliably.
Local privilege escalation in the Windows Telephony Service (TAPI) affects a broad range of Windows client and server releases, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. An authenticated local attacker can exploit a use-after-free (CWE-416) memory-corruption flaw to gain SYSTEM-level privileges; there is no public exploit identified at time of analysis and EPSS is very low (0.04%), but the CVSS 3.1 base score is 7.8 with total technical impact per CISA SSVC.
Local privilege escalation in the Windows Cloud Files Mini Filter Driver (cldflt.sys) lets an authenticated low-privileged user corrupt kernel memory via a use-after-free and gain SYSTEM-level control across a broad range of Windows 10, Windows 11, and Windows Server builds. Microsoft has released fixes, but SSVC reports no observed exploitation and EPSS is very low (0.04%), so this is a patch-on-schedule kernel EoP rather than an emergency; no public exploit identified at time of analysis. Because Cloud Files underpins OneDrive/cloud sync placeholders, the driver is present on effectively every modern Windows install.
Local information disclosure in the Microsoft Windows Desktop Window Manager (DWM) Core Library affects a broad range of Windows 10, Windows 11 (through 26H1), and Windows Server (2016-2025) builds, where a buffer over-read (CWE-126) lets an already-authenticated local attacker read adjacent process memory. Microsoft's CVSS 7.8 vector rates full confidentiality, integrity, and availability impact even though the description characterizes the outcome as information disclosure, so the leaked memory could plausibly aid further local escalation. There is no public exploit identified at time of analysis, EPSS is negligible (0.04%), and CISA SSVC marks exploitation as none, but a vendor patch is available.
Local privilege escalation in the Microsoft Windows TCP/IP networking stack allows an already-authenticated attacker to win a race condition and elevate to SYSTEM-level privileges across a broad range of Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025). Exploitation requires local, low-privileged access rather than remote reach, and Microsoft rates the technical impact as total (full confidentiality, integrity, and availability loss). There is no public exploit identified at time of analysis and EPSS probability is very low (0.04%), consistent with CISA SSVC marking exploitation as none and not automatable.
Local privilege escalation in Microsoft Windows Message Queuing (MSMQ) allows an authenticated low-privileged user to corrupt kernel/service memory through a double free (CWE-415) and elevate to SYSTEM. It affects a broad range of Windows client and server releases from Windows Server 2012/Windows 10 1607 through Windows 11 26H1 and Windows Server 2025 where the MSMQ feature is installed. There is no public exploit identified at time of analysis, EPSS is very low (0.04%), and CISA SSVC records no known exploitation, though the technical impact is rated total.

Microsoft has released a patch, and there is no public exploit identified at time of analysis; EPSS is negligible (0.04%) and CISA's SSVC rates exploitation as none, indicating this is a defense-in-depth fix rather than an emergency. The flaw is high-value as a post-compromise escalation primitive but requires local code execution and winning a race condition to trigger.
Remote code execution in the Windows Native WiFi Miniport Driver allows an unauthorized attacker on an adjacent network to win a timing race and run arbitrary code on affected Windows 10, Windows 11, and Windows Server systems. The flaw stems from improper synchronization of a shared resource in the kernel-mode wireless driver and carries a total (C:H/I:H/A:H) technical impact. No public exploit has been identified and EPSS is very low (0.07%), but successful exploitation grants full kernel-level compromise without authentication.
Remote code execution in Microsoft Windows DNS lets an unauthenticated attacker corrupt heap memory over the network and run arbitrary code on affected Windows 11 (22H3 through 26H1) and Windows Server 2022/2025 systems. The flaw is a CWE-122 heap-based buffer overflow rated CVSS 9.8, reported by Microsoft with a patch available; there is no public exploit identified at time of analysis, and the EPSS score is very low (0.07%), so this is a high-severity but not-yet-exploited issue. CISA SSVC flags it as automatable with total technical impact, meaning successful exploitation fully compromises the host.
Local privilege escalation in the Windows Ancillary Function Driver for WinSock (afd.sys) allows an already-authenticated low-privileged user to elevate to SYSTEM across Windows 10, Windows 11 (21H2 through 26H1), and Windows Server 2022/2025.

Microsoft has released patches; there is no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.04%), consistent with CISA SSVC rating exploitation as 'none'. The flaw is a serious defense-in-depth concern because it grants total confidentiality, integrity, and availability impact once a foothold exists, but it is not remotely reachable and requires prior local access.
Local privilege escalation in the Windows Common Log File System (CLFS) driver lets an already-authenticated low-privileged user gain SYSTEM-level rights on affected Windows client and server builds by triggering an integer underflow (CWE-191) in the driver's log-file parsing. The flaw yields total confidentiality, integrity, and availability impact on the local machine. There is no public exploit identified at time of analysis, EPSS risk is low (0.06%, 19th percentile), and CISA SSVC records exploitation status as none - but CLFS is a historically heavily-targeted attack surface, so patching is warranted.
Local privilege escalation in the Microsoft Windows Telephony Service (TAPI) lets an already-authenticated low-privileged user corrupt kernel/service memory via a use-after-free and gain elevated (typically SYSTEM-level) privileges across nearly all supported Windows client and server releases.

Microsoft has released fixes, but SSVC reports no observed exploitation and EPSS is very low (0.04%), so this is a patch-on-schedule kernel EoP rather than an emergency; no public exploit identified at time of analysis. Because Cloud Files underpins OneDrive/cloud sync placeholders, the driver is present on effectively every modern Windows install.
Local information disclosure in the Microsoft Windows Desktop Window Manager (DWM) Core Library affects a broad range of Windows 10, Windows 11 (through 26H1), and Windows Server (2016-2025) builds, where a buffer over-read (CWE-126) lets an already-authenticated local attacker read adjacent process memory. Microsoft's CVSS 7.8 vector rates full confidentiality, integrity, and availability impact even though the description characterizes the outcome as information disclosure, so the leaked memory could plausibly aid further local escalation. There is no public exploit identified at time of analysis, EPSS is negligible (0.04%), and CISA SSVC marks exploitation as none, but a vendor patch is available.
Local privilege escalation in the Microsoft Windows TCP/IP networking stack allows an already-authenticated attacker to win a race condition and elevate to SYSTEM-level privileges across a broad range of Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025). Exploitation requires local, low-privileged access rather than remote reach, and Microsoft rates the technical impact as total (full confidentiality, integrity, and availability loss). There is no public exploit identified at time of analysis and EPSS probability is very low (0.04%), consistent with CISA SSVC marking exploitation as none and not automatable.
Local privilege escalation in Microsoft Windows Message Queuing (MSMQ) allows an authenticated low-privileged user to corrupt kernel/service memory through a double free (CWE-415) and elevate to SYSTEM.
