Windows 10 Version 22H2
Monthly
Privilege escalation to full system control is achievable in Windows Storage Spaces Direct via a CWE-190 integer overflow that causes arithmetic wraparound, exploitable by an attacker with physical access to affected hardware. The flaw spans Windows 10 (versions 1607-22H2), Windows 11 (24H2-26H1), and Windows Server 2016 through 2025, representing a broad Microsoft platform footprint. Despite the C:H/I:H/A:H impact profile confirmed by SSVC as 'technical impact: total,' the physical access prerequisite (AV:P) is a hard constraint; SSVC additionally confirms exploitation status as none, no public exploit code exists, and EPSS sits at 0.31% (23rd percentile), making this a low operational priority for most organizations.
Cleartext transmission of sensitive information in the Windows Ancillary Function Driver for WinSock (afd.sys) enables a locally authenticated, low-privilege attacker to intercept or read sensitive data that the driver handles without adequate protection. Affected platforms span Windows 10 (multiple versions), Windows 11, and Windows Server 2012 through 2025 as confirmed by EUVD version data and Microsoft CPE strings. No public exploit has been identified at time of analysis, EPSS is extremely low at 0.21% (11th percentile), and CISA SSVC classifies this as no active exploitation with non-automatable attack paths, positioning this as a low-urgency but meaningful local disclosure risk.
Windows Media on multiple Windows client and server editions exposes sensitive information to authenticated local users, classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). Affected builds span Windows 10 1809 through Windows 11 26H1 and Windows Server 2019 through 2025, representing a broad footprint of Microsoft's supported OS ecosystem. No active exploitation has been identified at time of analysis - the vulnerability is absent from CISA KEV, EPSS sits at 0.36% (28th percentile), and SSVC assesses exploitation status as none - making this a patch-and-monitor priority rather than an emergency response.
Windows Secure Boot bypass across Windows 10 version 1809 through Windows 11 version 26H1 and multiple Windows Server editions allows an authorized local administrator to circumvent boot-time integrity protections by exploiting a non-updateable boot chain component. A successful attacker can subvert the UEFI Secure Boot trust chain to load unsigned or malicious code at the pre-OS stage, enabling persistent bootkit or rootkit implantation that survives OS reinstallation. No public exploit code has been identified and CISA SSVC reports no active exploitation, though the SSVC technical impact rating of 'total' correctly reflects full defeat of the boot integrity boundary.
Windows Filtering Platform (WFP) on affected Windows 10, Windows 11, and Windows Server releases exposes an improper access control flaw (CWE-284) that enables a locally authenticated, low-privileged attacker to bypass a host-based security feature. The bypass is limited to confidentiality and integrity impacts (no availability), scoped to the vulnerable system, and requires no user interaction once local execution is established. No public exploit code exists and CISA has not added this to the KEV catalog; EPSS at 0.04% (11th percentile) and SSVC exploitation status of 'none' corroborate the low probability of near-term opportunistic weaponization.
Null pointer dereference in the Windows LDAP (Lightweight Directory Access Protocol) component enables a low-privileged local attacker to crash the LDAP service, causing a denial of service on all affected Windows 10, Windows 11, and Windows Server releases. The vulnerability carries a CVSS 3.1 score of 5.5 with a strictly local attack vector (AV:L/PR:L), confining impact to availability only - no data exfiltration or code execution is possible. With EPSS at 0.04% (11th percentile), SSVC exploitation status of 'none,' no KEV listing, and no public exploit identified, real-world exploitation risk is currently low despite the enormous Windows install base.
Privilege escalation via double free in the Windows Rich Text Edit Control (RichEdit) affects an exceptionally broad range of Microsoft platforms, spanning Windows 10 versions 1607 through 22H2, all current Windows 11 branches through 26H1, and Windows Server 2012 through Server 2025. A low-privileged local attacker who can induce user interaction with crafted RTF content can corrupt heap memory to achieve full compromise of confidentiality, integrity, and availability - consistent with the SSVC 'total technical impact' rating. No public exploit code exists and no active exploitation has been identified (not in CISA KEV), and the EPSS score of 0.05% at the 16th percentile reflects a minimal current exploitation signal; however, the sheer scale of the affected Windows install base keeps this relevant for enterprise patch cadence. A notable discrepancy exists: the CVE tags classify this as 'Information Disclosure,' which conflicts with Microsoft's own description of local privilege elevation - the CVSS C:H/I:H/A:H impact metrics and SSVC total-impact rating support the privilege escalation characterization, suggesting the tag is erroneous.
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.
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.
Improper access control in Universal Plug and Play (upnp.dll) on Windows allows authenticated local attackers to disclose sensitive information without user interaction. The vulnerability affects Windows 10 (versions 1607, 1809, 21H2, 22H2), Windows 11 (versions 22H3, 23H2, 24H2, 25H2, 26H1), and Windows Server 2012-2025. Microsoft has released patches available through their security update guide; no public exploit code or active exploitation has been reported at time of analysis.
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.
Improper link resolution in Windows UPnP (upnp.dll) allows authenticated local attackers to disclose sensitive information through symlink following. The vulnerability affects Windows 10 versions 1607-22H2, Windows 11 versions 22H3-26H1, and Windows Server 2012-2025. With local access and standard user privileges, an attacker can read files outside their normal access scope via crafted UPnP operations.
