EPSS sits at 0.38% (30th percentile) with no CISA KEV listing and SSVC exploitation status of 'none,' indicating no confirmed or publicly observed active exploitation at time of analysis; however, kernel information leaks of this class are routinely used to stage ASLR-bypass steps in multi-stage privilege escalation chains.
Privilege escalation to SYSTEM level is achievable in the Windows USB Video Class (UVC) driver across a broad swath of Windows 10, 11, and Server editions via physical connection of a malicious USB device. The heap-based buffer overflow (CWE-122) is triggered when the driver processes attacker-controlled UVC descriptors from a crafted device, corrupting kernel heap memory. No active exploitation is confirmed (absent from CISA KEV, SSVC exploitation=none), and EPSS sits at 0.37% (29th percentile), consistent with the physical access barrier that makes mass exploitation impractical.
LSASS denial-of-service in Microsoft Windows enables authenticated network attackers to exhaust resources in the Local Security Authority Subsystem Service, crashing it and forcing a system reboot across a wide range of Windows 10, 11, and Server releases spanning Windows Server 2012 through Server 2025. Microsoft has released patched builds via its standard update cycle; no public exploit code exists and CISA has not listed this in KEV. Despite the broad product footprint, EPSS of 0.79% and SSVC exploitation status of 'none' indicate low current threat activity, though domain controllers represent elevated-risk targets due to LSASS's role as the authentication hub.
Integer overflow in Windows Storage Spaces Direct enables an unauthenticated attacker with physical access to execute arbitrary code on affected Windows client and server platforms. The CVSS vector (AV:P/AC:L/PR:N/UI:N, C:H/I:H/A:H) confirms that no credentials are required but direct physical presence at the target hardware is mandatory, substantially narrowing the realistic attacker pool. No public exploit identified at time of analysis; SSVC rates exploitation as 'none' and EPSS stands at 0.33% (26th percentile), consistent with a physical-vector vulnerability not currently observed in opportunistic campaigns.
Out-of-bounds read in the Windows USB Audio Class driver (usbaudio.sys) enables physical attackers to disclose kernel memory contents across a broad range of Windows 10, Windows 11, and Windows Server releases. Exploitation requires plugging a crafted USB audio device into the target machine, making remote attack impossible by design. No public exploit exists and SSVC exploitation status is confirmed as none, though the High confidentiality impact rating reflects that kernel memory disclosure can expose sensitive in-memory data if triggered.
Link-following vulnerability in Windows upnp.dll (Universal Plug and Play) enables a locally authenticated attacker with standard user privileges to read files outside intended access boundaries by planting symbolic links or junction points that the service resolves without proper validation. Affected scope spans Windows 10 (versions 1607-22H2), Windows 11 (versions 24H2-26H1), and Windows Server 2012 through 2025. No public exploit has been identified at time of analysis; EPSS of 0.27% (19th percentile) and CISA SSVC exploitation status of 'none' collectively indicate low near-term exploitation probability.
Windows File Explorer on virtually all supported Microsoft Windows desktop and server editions leaks sensitive information to locally authenticated low-privileged users, classified under CWE-200. The flaw allows a local attacker holding only a standard account to access data that should be restricted to higher-privileged processes - with no user interaction required (UI:N) and low attack complexity (AC:L). Despite the high confidentiality impact in the CVSS vector, EPSS sits at just 0.36% (28th percentile) and SSVC confirms exploitation as 'none' and the attack as not automatable, placing this firmly in the category of a patch-cycle priority rather than an emergency response. No public exploit has been identified at time of analysis.
Out-of-bounds read in the Windows Kernel (CWE-125) enables a locally authenticated attacker with standard user privileges to bypass a kernel security feature and read kernel memory contents. Confirmed by Microsoft (MSRC) across Windows 10, Windows 11, and Windows Server 2012 through 2025 editions, with patches available for all affected builds. No public exploit code and no CISA KEV listing exist at time of analysis; EPSS at 0.29% (20th percentile) and SSVC exploitation status of 'none' together signal low current exploitation activity, though the kernel memory disclosure primitive is a classic KASLR-defeat building block in chained exploits.
Null pointer dereference in Windows Active Directory Domain Services (AD DS) enables a low-privileged authenticated attacker to crash the service remotely, causing denial of service across the affected domain. The flaw spans a wide range of Windows client and server releases, from Windows 10 version 1607 through Windows 11 version 26H1 and Windows Server 2012 through 2025. No public exploit code has been identified and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog at time of analysis, though the network-accessible attack surface and low privilege requirement lower the bar for abuse in environments with broad domain user access.
Security feature bypass in Microsoft XML (MSXML) across Windows 10, Windows 11, and Windows Server 2012 through 2025 requires an attacker with physical access to the target device to exploit an untrusted search path condition. The vulnerability allows an unauthorized attacker to subvert the library or executable resolution order, enabling them to load attacker-controlled code that circumvents Windows security controls. No public exploit has been identified at time of analysis, and SSVC assessment confirms zero observed exploitation, though the technical impact if successfully executed is rated total (full compromise of confidentiality, integrity, and availability).
Windows Remote Desktop Protocol (RDP) client leaks sensitive memory contents due to use of an uninitialized resource (CWE-908), allowing a network-accessible attacker to disclose potentially high-value information from a victim's system. Exploitation requires user interaction - a victim must connect to an attacker-controlled RDP endpoint - making this a client-side information disclosure attack affecting Windows 10 (all supported versions from 1607 through 22H2), Windows 11 (24H2 through 26H1), and Windows Server 2012 through 2025. No public exploit code has been identified and no active exploitation is confirmed; however, the CVSS confidentiality impact is rated High, meaning exposed memory could include credentials or session tokens.
Information disclosure via uninitialized memory in the Windows SMB driver stack affects a broad range of Windows 10, Windows 11, and Windows Server versions. A locally authenticated, low-privileged attacker can trigger a code path that reads from uninitialized memory within the SMB subsystem, potentially leaking sensitive kernel or heap memory contents. No public exploit code or active exploitation has been identified at the time of analysis; Microsoft has released a patch via MSRC.
Out-of-bounds read in the Windows TCP/IP stack exposes kernel or process memory to locally authenticated low-privileged users across a broad range of Windows 10, Windows 11, and Windows Server releases spanning from Server 2012 through Server 2025. The CWE-125 root cause allows an authorized local attacker with standard user credentials to read memory regions outside allocated buffer boundaries in the TCP/IP component, yielding high-confidentiality-impact information disclosure with no integrity or availability consequence. No public exploit code exists and no active exploitation has been identified (EPSS: 0.31%, 22nd percentile; SSVC exploitation status: none), placing this in a lower-priority remediation tier despite its exceptionally broad product footprint.
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 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.
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.

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.
