Windows 10 Version 1607
Monthly
Information disclosure in the Windows TCP/IP networking stack allows a remote, unauthenticated attacker to read sensitive memory contents over the network by triggering a use-after-free condition. All supported Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025) are affected. Microsoft-reported with no public exploit identified at time of analysis; EPSS is low (0.06%, 19th percentile) and CISA SSVC records exploitation status as none.
Local privilege escalation in the Microsoft Windows TCP/IP networking stack allows an authorized (low-privileged) attacker to run code with SYSTEM-level rights by triggering a stack-based buffer overflow (CWE-121). The flaw affects a broad range of Windows 10, Windows 11, and Windows Server releases and carries a CVSS 7.8 with total technical impact per CISA SSVC. There is no public exploit identified at time of analysis, EPSS is very low (0.06%, 19th percentile), and it is not listed in CISA KEV, indicating no observed exploitation to date.
Heap-based buffer overflow in the Windows Volume Manager Extension Driver enables an authorized attacker with physical device access to execute arbitrary code, achieving full system compromise across a broad range of Windows 10, Windows 11, and Windows Server editions. Affected product versions span from Windows Server 2012 through Windows 11 26H1 and Windows Server 2025, per EUVD-2026-29656 data. No active exploitation has been confirmed (not in CISA KEV), and EPSS at 0.07% (22nd percentile) reflects the extremely low probability of widespread exploitation given the dual prerequisite of physical presence and high-privilege credentials.
Local privilege escalation in Windows Cryptographic Services lets an authenticated low-privileged user corrupt heap memory (CWE-122) to gain SYSTEM-level control across supported Windows 10, Windows 11, and Windows Server builds. There is no public exploit identified at time of analysis and EPSS is very low (0.04%), but SSVC rates the technical impact as total, and Microsoft has released patches. Because it requires prior local access, it is a post-compromise escalation primitive rather than an initial-access threat.
Denial of service in the Windows Internet Key Exchange (IKE) protocol implementation allows remote unauthenticated attackers to exhaust host memory across all supported Windows client and server releases (Windows 10 1607 through Windows 11 26H1, Windows Server 2012 through Server 2025). The flaw is a memory leak (CWE-401) triggered over the network with no privileges or user interaction, but impact is limited to availability with no data exposure. There is no public exploit identified at time of analysis, and EPSS exploitation probability is very low (0.08%, 23rd percentile).
Out-of-bounds read in the Windows Telnet Client exposes memory contents and minor availability degradation to network-based attackers who control a Telnet server endpoint. Affected systems span Windows 10 (1607 through 22H2), Windows 11 (22H3 through 26H1), and Windows Server 2012 through 2025, all requiring user interaction to initiate a Telnet session against a malicious server. No public exploit identified at time of analysis and no active exploitation confirmed (not in CISA KEV); EPSS stands at 0.05% (16th percentile), reinforcing that real-world exploitation risk is low despite the broad platform footprint.
Windows TCP/IP stack allows a low-privilege network-authenticated attacker to bypass a security feature by exploiting an alternate path or channel (CWE-288), resulting in a high-integrity impact without requiring user interaction. Affected scope spans Windows 10 (versions 1607 through 22H2), Windows 11 (versions 22H3 through 26H1), and Windows Server 2012 through Server 2025, making the exposure footprint extremely broad. No public exploit code exists and no active exploitation is confirmed at time of analysis; EPSS at 0.06% (18th percentile) and SSVC classification of 'exploitation: none, automatable: no' indicate low near-term weaponization risk despite the wide attack surface.
Local code execution in the Windows Graphics Device Interface (GDI) component affects a broad range of Windows client and server releases from Windows Server 2012 through Windows 11 25H2/26H1 and Server 2025. An attacker who convinces a user to open a maliciously crafted file or content triggers a heap-based buffer overflow (CWE-122) in GDI, running arbitrary code in the victim's context with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis, EPSS is very low (0.06%), and CISA SSVC records no known exploitation, so this is a patch-on-cycle item rather than an emergency.
Windows Snipping Tool leaks sensitive information to unauthenticated network attackers via user interaction, enabling spoofing attacks. The vulnerability affects Windows 10 (versions 1607, 1809, 21H2, 22H2) and Windows 11 (versions 22H3, 23H2, 24H2, 25H2, 26H1), as well as Windows Server 2012 through 2025. Microsoft has released patches for all affected versions; exploitation requires user interaction but no specialized technical knowledge.
Remote code execution in Windows IKE Extension (Internet Key Exchange) via double free memory corruption allows unauthenticated network attackers to execute arbitrary code on Windows 10 (1607-22H2), Windows 11 (22H3-26H1), and Windows Server (2016-2025). CVSS 9.8 critical severity with network vector requiring no authentication or user interaction. Vendor patch released by Microsoft addresses CWE-415 double free weakness. EPSS score of 0.07% (21st percentile) suggests low observed exploitation probability despite critical severity rating, indicating this may be a targeted or difficult-to-exploit vulnerability in production environments. No CISA KEV listing or public POC identified at time of analysis.
Remote code execution in Windows TCP/IP networking stack across Windows 10, 11, and Server versions allows unauthenticated network attackers to execute arbitrary code by exploiting a race condition in shared resource synchronization. The vulnerability affects all supported Windows versions from Server 2012 through Windows 11 26H1 and Server 2025. Microsoft has released patches addressing this high-severity flaw (CVSS 8.1). No public exploit identified at time of analysis, though SSVC assessment
