An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds low-level authorization on the network send crafted DNS requests that cause the service to read past the end of an allocated buffer, potentially returning memory contents to the attacker (CVSS 6.5, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only hosts actually running the DNS Server role - typically domain controllers and dedicated DNS servers rather than standard workstations - are exposed, and exploitation requires the PR:L authorization the assessed vector specifies, so this is not an unauthenticated flaw. Impact is limited to confidentiality disclosure with no integrity or availability effect; no public exploit has been identified at time of analysis, and a vendor patch is available from Microsoft.
An out-of-bounds read in the Windows DNS Server role lets an authorized, authenticated attacker send a crafted DNS request that causes the service to read past the end of an allocated buffer and return information it should not disclose over the network. Exploitation requires the DNS Server role to be installed and reachable, and the attacker must already hold a low-privileged position able to send requests to the DNS service (CVSS PR:L, unauthenticated access is not sufficient per the assessed vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N); there is no integrity or availability impact, and no user interaction is required. Only Windows client and server builds running the DNS Server role below the patched versions listed in the EUVD data are affected; no public exploit identified at time of analysis, and this is assessed as a moderate authenticated information-disclosure flaw rather than a top-tier emergency.
Information disclosure in Microsoft Windows DNS Server is caused by an out-of-bounds read that a low-privileged, authenticated attacker can trigger over the network to leak memory contents from an affected unpatched system. The issue affects DNS components in Windows Server 2012 through 2025 and Windows 10/11, and exploitation requires network reachability plus authorized low-privilege access as reflected by CVSS PR:L and UI:N. Vendor patches are available, and no public exploit was identified at time of analysis; this is a moderate information-disclosure issue rather than a critical remote-code-execution emergency.
Out-of-bounds read in the Windows DNS Server role lets an attacker who holds low-level authorization (authenticated, PR:L) disclose server memory contents over the network, giving a high confidentiality impact with no integrity or availability effect (CVSS 6.5, CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only Windows hosts that have the DNS Server role installed and reachable over the network are exposed; the flaw lives in that role's request-parsing path, so Windows systems without the role are not affected, and EUVD enumerates the vulnerable build ranges across Windows 10, Windows 11, and Windows Server 2012 through 2025. There is no confirmed active exploitation (CISA KEV) and no public exploit identified at time of analysis, while a vendor patch is available per the Microsoft advisory.
An out-of-bounds read in the Windows DNS Server role allows an attacker who already holds low-level authorization on or toward the target to read beyond the bounds of an allocated buffer and disclose server memory over the network (CVSS 6.5, CWE-125, PR:L). Only hosts running the DNS Server role are in scope - domain controllers and dedicated DNS servers on Windows Server 2012 through 2025 and supported Windows 10/11 builds - so the network vector does not translate into an anonymous internet-wide attack. Microsoft has published vendor updates for the affected builds, and no public exploit identified at time of analysis; impact is confidentiality-only, with no integrity or availability effect.
Information disclosure in the Windows DNS Server role allows a remote attacker holding valid low-privilege credentials (CVSS PR:L) to read out-of-bounds memory by sending a crafted DNS request, leaking data over the network with high confidentiality impact but no integrity or availability effect. Only pre-patch Windows Server and Windows 10/11 builds with the DNS Server role installed and reachable are affected, and exploitation requires that the attacker can already query or reach the DNS service rather than being an anonymous internet-wide attacker. There is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis, though the vendor has released a patch and the flaw carries a moderate CVSS base score of 6.5.
Memory disclosure via an out-of-bounds read in the Windows DNS Server service allows a remote, authenticated low-privilege attacker to leak server process memory over the network. Affected deployments are Windows Server 2012 through Windows Server 2025 (including Server Core) and Windows 10/11 builds running the DNS Server role that have not been updated to the fixed builds listed by Microsoft; no public exploit identified at time of analysis. The assessed impact is information disclosure only (CVSS 6.5, C:H/I:N/A:N) with no code execution or denial of service, but leaked memory may expose sensitive data that aids follow-on attacks.
Out-of-bounds read in the Microsoft Windows DNS Server role lets an authenticated, low-privileged attacker reachable over the network read past the end of a buffer and disclose information from server memory, rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). The flaw affects a broad set of Windows client and server builds running the DNS Server role, enumerated by EUVD-2026-100438, and exposure is limited to confidentiality - integrity and availability are unaffected and no user interaction is required. There is no CISA KEV listing and no public exploit identified at time of analysis; the PR:L vector means the attacker must already hold low-level credentials, which constrains opportunistic mass exploitation, and vendor patches are available.
An out-of-bounds read in the Windows DNS Server role allows an authenticated attacker with low-level privileges to disclose sensitive information over the network. This medium-severity (CVSS 6.5) flaw affects many Windows Server and Windows client versions when the DNS Server role is installed, including Windows Server 2012 through 2025 and Windows 10/11 builds prior to the fixed versions listed in Microsoft’s advisory. No public exploit code or active exploitation has been identified at time of analysis, and a vendor patch is available.
Information disclosure in the Windows DNS Server role allows an authenticated, low-privilege network attacker to trigger an out-of-bounds read that leaks memory contents in responses. Tracked as CVE-2026-97835 (CVSS 6.5, CWE-125, C:H/I:N/A:N), it affects the DNS Server component across Windows 10, Windows 11, and Windows Server 2012 through 2025, but only on hosts where the DNS Server role is actually installed and reachable - typically domain controllers and dedicated DNS hosts in Active Directory environments. Exploitation requires low-privilege credentials (PR:L via CVSS:3.1/AV:N/AC:L/PR:L/UI:N), not fully anonymous access, and the outcome is limited to confidentiality loss with no code execution, tampering, or denial of service. Vendor patching is available from Microsoft and no public exploit code or confirmed active exploitation was identified at time of analysis.
An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds valid low-level credentials on the network cause the service to read past the bounds of a memory buffer, disclosing sensitive information over the network. This is a medium-severity (CVSS 6.5) information-disclosure flaw rated AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N - exploitation requires a reachable, running DNS Server role (typically on domain controllers or dedicated DNS hosts) and at least low-level authorization, but needs no user interaction and has low attack complexity. The privilege prerequisite narrows the attacker population and the impact is confined to confidentiality: there is no code execution, integrity, or availability impact, and no public exploit identified at time of analysis. A vendor patch is available.
Information disclosure in the Windows DNS Server role allows a network-positioned attacker holding a low level of authorization (CVSS PR:L, described by Microsoft as an 'authorized attacker') to trigger an out-of-bounds read and leak data from server memory. The issue is rated CVSS 6.5 with confidentiality impact only and no integrity or availability effect, and it affects a wide range of unpatched Windows Server and Windows client builds that enable the DNS Server role, from Windows Server 2012 through Windows Server 2025 plus Windows 10 and Windows 11 releases. No public exploit code has been identified at time of analysis, there is no CISA KEV listing indicating active exploitation, and Microsoft has published a patched update; systems already at the fixed build numbers in the vendor advisory are not affected.
Information disclosure in the Windows DNS Server role lets an authenticated, low-privileged attacker read past the bounds of an allocated buffer and leak memory contents over the network. The flaw (CWE-125, out-of-bounds read) affects a broad set of Windows Server builds - Server 2012, 2012 R2, 2016, 2019, 2022 and 2025, including Server Core installations - plus Windows 10 (1607, 1809, 21H2, 22H2) and Windows 11 (23H2, 24H2, 25H2, 26H1, 26H2), and only exposed systems that have the DNS Server role installed and reachable. Impact is limited to confidentiality (CVSS 6.5, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) with no integrity or availability effect; no public exploit has been identified at time of analysis, and vendor-released patches are available per the Microsoft advisory.
An out-of-bounds read (CWE-125) in the Windows DNS Server role allows a remote attacker holding some level of valid privilege (CVSS PR:L) to leak server memory contents over the network, resulting in information disclosure only. Successful exploitation requires network reachability to a DNS Server host and prior access to the DNS service - it is not anonymously exploitable from the internet - while no user interaction (UI:N) and only low attack complexity (AC:L) are needed. The confidentiality impact is rated High but integrity and availability are unaffected, and no public exploit code or confirmed active exploitation has been identified at time of analysis; vendor patches are available, making this a genuine but moderate-priority issue rather than an emergency.
An out-of-bounds read in Microsoft's Windows DNS Server role lets an attacker who already holds low-level authorized network access (PR:L) leak process memory across the network, producing a high confidentiality impact with no integrity or availability effect. Exploitation is limited to hosts where the DNS Server role is installed and reachable, and the authentication prerequisite rules out anonymous internet-wide attacks, so the issue is rated CVSS 6.5 and treated as moderate rather than emergency priority. No public exploit code and no confirmed active exploitation (CISA KEV) were identified in the available intelligence, though vendor patches are available for all affected branches.
Information disclosure in Windows DNS Server allows an authenticated attacker with low privileges to read sensitive memory contents over the network. This buffer over-read affects numerous Windows Server and Windows client versions, including Server 2012 through 2025 and Windows 10/11 builds. No public exploit has been identified at time of analysis, and vendor patches are available.
An out-of-bounds read (CWE-125) in the Windows DNS Server service lets an attacker who already holds low-level credentials read beyond a buffer and disclose in-memory information over the network, rated CVSS 6.5 with a confidentiality-only impact and no effect on integrity or availability. Exploitation requires authentication (CVSS PR:L), network reachability to a host actually running the DNS Server role, and low attack complexity with no user interaction, so this is a moderate-priority authenticated information-disclosure flaw rather than a pre-authentication remote code execution issue. Affected systems span Windows Server 2012 through Server 2025 (including Server Core installs) and several Windows 10 and Windows 11 client releases; Microsoft has published a fix through its update guide, and no public exploit code was identified at time of analysis.
Information disclosure in the Microsoft Windows DNS Server role lets an authenticated, network-positioned attacker trigger an out-of-bounds read and retrieve memory contents over the network. The flaw (CWE-125) affects a wide span of Windows builds where the DNS Server role is installed and running - Windows Server 2012, 2012 R2, 2016, 2019, 2022 and 2025, plus Windows 10 (1607-22H2) and Windows 11 (23H2 through 26H2) - and requires only low-privilege access (CVSS:3.1/AV:N/AC:L/PR:L/UI:N with C:H/I:N/A:N, base 6.5) with no user interaction; impact is confined to confidentiality, with no integrity or availability effect. There is no public exploit code identified at time of analysis and the issue is not listed on CISA KEV, but Microsoft has published vendor fixes, so patching priority is driven by the sensitivity of data exposed by DNS infrastructure rather than by observed exploitation.
An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds authorized access to the DNS service (CVSS PR:L) disclose memory contents over the network, with no user interaction required (UI:N) and low attack complexity (AC:L). Impact is strictly confidentiality (C:H/I:N/A:N) - there is no code execution, data modification, or denial of service, and only Windows and Windows Server builds with the DNS Server role enabled are exposed. This is a genuine but moderate-priority issue rather than a top-tier emergency: CISA SSVC records Exploitation as 'none' and Automatable as 'no', and no public exploit code has been identified at time of analysis, though a vendor patch is available.
Out-of-bounds read in Windows DNS Server allows authenticated remote attackers with low-level privileges (PR:L) to disclose sensitive information from process memory over the network. Affected versions include Windows Server 2012 through 2025 and various Windows 10/11 builds hosting the DNS Server role, as detailed in the EUVD advisory. Vendor patches are available, and no public exploit code or active exploitation is identified at time of analysis; the CVSS score of 6.5 reflects high confidentiality impact but requires prior authentication, making this a moderate-priority issue.
Out-of-bounds read in Windows DNS Server allows an authenticated, low-privileged attacker to disclose sensitive memory contents over the network, affecting Windows Server 2012 through Server 2025 and Windows 10/11 systems that have the DNS Server role enabled. The flaw is rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), is a CWE-125 read-only disclosure with no integrity or availability impact, and has no public exploit identified at time of analysis; vendor patches are available.
An out-of-bounds read in the Microsoft Windows DNS Server service lets an authorized, network-positioned attacker cause the server to read past the bounds of an allocated buffer and return the resulting memory contents within DNS responses (CVSS 3.1 base 6.5, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only hosts that have the DNS Server role installed and running on unpatched Windows 10, Windows 11, or Windows Server builds are affected; the PR:L requirement means the actor must already be authorized to submit queries or data that reach the vulnerable parser, so anonymous Internet clients are not sufficient. Impact is limited to information disclosure of server memory with no integrity or availability effect, and no public exploit identified at time of analysis. Microsoft has released updates that raise each affected build to a fixed revision.
Information disclosure in the Microsoft Windows DNS Server role allows an authenticated, low-privileged attacker to trigger an out-of-bounds read and leak memory contents over the network. The flaw affects Windows Server 2012 through Server 2025 as well as multiple Windows 10 and Windows 11 builds, and carries a CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), so impact is confined to confidentiality with no integrity or availability effect and no code execution or denial of service implied. Vendor-released patches exist as fixed build numbers per the EUVD data and the MSRC advisory, and no public exploit identified at time of analysis (no KEV or POC signal in the provided intelligence).
An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds low-level authorization on the network read memory beyond intended buffer boundaries and disclose that information over the network. Only hosts running the DNS Server role are affected, spanning Windows Server 2012 through 2025 (including Server Core installations) plus Windows 10 and Windows 11 clients that host the role; exploitation requires an authenticated/authorized position (CVSS PR:L) with network reachability to the DNS service, so it is not an unauthenticated remote flaw. Impact is limited to confidentiality (C:H) with no integrity or availability effect, and no public exploit code has been identified at time of analysis - the practical risk concentrates in environments where low-privilege accounts or internal footholds can reach a DNS server.
An out-of-bounds read (CWE-125) in the Microsoft Windows DNS Server role allows an attacker holding low-privilege authenticated access to disclose information over the network. Only hosts actually running the DNS Server role are exposed; the flaw is rated CVSS 6.5 with high confidentiality impact but no integrity or availability impact, and exploitation requires authorized (PR:L) rather than unauthenticated network access. Patched builds are available from the vendor per the MSRC update guide, and no public exploit code or active exploitation has been identified at time of analysis.
Heap-based buffer overflow in Windows DNS Server allows an authenticated, low-privilege attacker with network access to disclose sensitive information from server memory. The vulnerability affects numerous Windows Server and Windows 10/11 builds that have the DNS Server role installed, with no public exploit identified at time of analysis. Although rated CVSS 6.5 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, the confidentiality-only impact and requirement for authentication limit the realistic threat to information leakage rather than code execution or denial of service.
Heap memory disclosure in Microsoft Windows Hyper-V lets an authenticated, low-privileged principal - such as an account inside a guest VM or a low-rights user able to reach the Hyper-V service over the network - read leaked contents of the hypervisor's heap, affecting Windows 10, Windows 11 (23H2 through 26H2), and Windows Server 2019, 2022, and 2025 including Server Core installations. The flaw carries a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), meaning no user interaction and low attack complexity are required, but the attacker must already hold valid credentials and the outcome is read-only: confidentiality is fully impacted while integrity and availability are untouched, so hosts without the Hyper-V role enabled are not exposed. No public exploit been identified at time of analysis, and Microsoft has published fixed builds via its MSRC update guide.
Local information disclosure in the Windows Client Side Caching driver (csc.sys) lets an authenticated attacker who already holds low-level privileges on a Windows host read sensitive data that should be restricted, such as contents of the Offline Files cache. The flaw affects default installations across Windows 10 (1607 through 22H2), Windows 11 (23H2 through 26H2), and Windows Server 2012 through 2025, and requires only local access with no user interaction (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, base 5.5). There is no public exploit identified at time of analysis, CISA's SSVC rates exploitation as 'none' and the issue as non-automatable with partial technical impact, and Microsoft has released patched builds - making this a post-compromise disclosure primitive rather than a remote entry point.
Local privilege escalation in the Windows Distributed File System (DFS) lets an authenticated attacker with valid host credentials trigger a heap-based buffer overflow (CWE-122) and elevate to SYSTEM on unpatched Windows 10, Windows 11, and Windows Server builds. Exploitation is local only with no user interaction and, per Microsoft's advisory, requires existing high privileges, so realistic exposure is limited to shared, multi-user, or terminal-server hosts where an untrusted authenticated principal is present. No public exploit code has been identified at time of analysis and CISA's SSVC rates exploitation as none; vendor patches are available.
Information disclosure in the Windows NTFS file system driver allows an authenticated local attacker to read sensitive system information that should be restricted to a higher privilege level. The flaw affects Windows 10, Windows 11, and Windows Server installations on NTFS volumes below their respective patched builds; exploitation requires pre-existing local code execution or interactive access as a low-privileged user (CVSS PR:L), with no remote vector and no user interaction (UI:N). No public exploit code has been identified at time of analysis, and Microsoft has released vendor patches.
An out-of-bounds read in the Windows Universal Disk Format File System (UDFS) kernel-mode driver lets a locally authenticated attacker disclose information - potentially kernel memory contents - on an affected host. Exploitation requires existing local access and the ability to feed crafted UDF-formatted content (a mounted ISO/UDF image, removable USB media, or a virtual volume) to the driver; the vulnerability is not remotely reachable, cannot be triggered unauthenticated, and has no integrity or availability impact, which is why CISA's SSVC rates it non-exploited and non-automatable. Microsoft has shipped fixed builds for every affected Windows 10, Windows 11, and Windows Server release, and no public exploit code has been identified at time of analysis, making this a moderate-severity, low-priority issue despite affecting a kernel-mode component present by default on all listed platforms.
An out-of-bounds read in the Windows NTFS file system driver (ntfs.sys) lets an authenticated local user with low privileges read memory contents beyond an allocated buffer, resulting in local information disclosure (CWE-125, CVSS 3.1 5.5). Only hosts that have not applied Microsoft's current cumulative updates are affected; the EUVD data lists a broad range of client and server branches below their respective fixed builds (?fix versions include Windows 11 23H2 10.0.22631.7652, 24H2 10.0.26100.9711, 25H2 10.0.26200.9711, Windows 10 1607/Server 2016 10.0.14393.9612, and Windows 10 1809/Server 2019 10.0.17763.9376). There is no remote vector and CISA SSVC rates the flaw as non-automatable with only partial technical impact, and no public exploit code has been identified at time of analysis, so this is a genuine but low-priority disclosure primitive rather than a path to privilege escalation.
Information disclosure in the Microsoft Windows NTFS filesystem driver allows a local, low-privileged, authenticated attacker to read portions of kernel memory by triggering an integer underflow (wraparound) during a crafted NTFS operation, with no user interaction required. Exploitation is confined to the local attack vector (CVSS:3.1/AV:L/AC:L/PR:L/UI:N) and yields confidentiality impact only (C:H/I:N/A:N, score 5.5) - there is no write, code-execution, or denial-of-service effect, and CISA's SSVC analysis rates the issue as not automatable with no known exploitation. No public exploit code has been identified at time of analysis, and Microsoft has released a vendor patch covering all affected Windows client and server builds.
Information disclosure in Windows Message Queuing (MSMQ) Queue Manager allows an authenticated local attacker to read data from an affected host via a type confusion flaw. Exploitation requires the optional MSMQ feature to be installed and the Queue Manager service running (not enabled by default), and impact is limited to confidentiality with no code execution or privilege escalation. Microsoft has released patches; no public exploit or active exploitation has been identified at time of analysis.
Local information disclosure in the Microsoft Windows Search Component lets an authenticated low-privileged user read out-of-bounds memory contents on the affected host, giving a post-foothold attacker a confidentiality-only leak (CVSS 5.5, AV:L/PR:L/UI:N/S:U/C:H/I:N/A:N) with no integrity or availability impact. Every current Windows client and server branch is affected - Windows 10 1607/1809/21H2/22H2, Windows 11 23H2/24H2/25H2/26H1/26H2, and Windows Server 2012 through 2025 including Server Core - so the exposure is broad even though the flaw cannot be used for remote initial access. No public exploit identified at time of analysis: CISA SSVC records Exploitation: none and Automatable: no, CISA KEV does not list this CVE, and no EPSS signal was provided; urgency is driven by patch hygiene rather than active threat activity. Microsoft has released fixes (see the MSRC update guide referenced below).
Information disclosure in the Windows Secure Kernel Mode component lets a locally authenticated attacker with low privileges read sensitive system information that should remain isolated inside the hypervisor-protected secure kernel, affecting Windows 10, Windows 11 and Windows Server 2016 through 2025 builds that predate Microsoft's fixed versions. Exploitation is constrained by high attack complexity and state-dependent conditions (CVSS AC:H, PR:L, AV:L), and there is no public exploit identified at time of analysis; CISA's SSVC assessment rates exploitation as none, the attack as non-automatable, and technical impact as partial. Microsoft has released patches, so this is a moderate-priority hardening item rather than an emergency response.
Information disclosure in the Windows USB Print Driver allows a locally authenticated, low-privilege attacker to read beyond intended buffer boundaries and leak contents of driver memory on affected Windows 10, Windows 11, and Windows Server builds (2012 through 2025, including Server Core installations). Exploitation requires an existing foothold on the host with the ability to exercise the USB print driver code path (CVSS:3.1/AV:L/AC:L/PR:L/UI:N), needs no victim interaction, and is limited to confidentiality impact - no data modification, no denial of service, and no remote vector. No public exploit code has been identified at time of analysis, CISA's SSVC assessment records exploitation as 'none' with partial technical impact, and an EUVD record (EUVD-2026-99784) tracks the same affected build list; vendor patches are available, making this a genuine but lower-tier patching priority compared with remotely reachable issues.
Out-of-bounds read in Windows Imaging Component (WIC) allows a locally authenticated attacker to disclose in-process memory contents when WIC processes a crafted or attacker-influenced image, with a CVSS of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Affected systems include a broad set of supported Windows 10, Windows 11, and Windows Server builds below their patched build thresholds, and exploitation requires prior low-privileged access to the host rather than remote network reachability. No public exploit identified at time of analysis, CISA SSVC reports exploitation none and automatable no, and Microsoft has released vendor updates to address the flaw.
Local tampering with Windows Security Account Manager (SAM) data is possible on unpatched Windows hosts because a critical SAM function performs no authentication or authorization check, letting an authenticated local user modify integrity-sensitive account information. Exploitation requires a pre-existing local session (AV:L, PR:L) and affects only integrity (C:N/A:N), so the practical impact is moderate rather than catastrophic, and no public exploit identified at time of analysis - SSVC rates exploitation as none and automatable as no. The flaw spans Windows 10 21H2/22H2, Windows 11 23H2 through 26H2, and Windows Server 2022/2025 (including Server Core), all of which have vendor fixes available.
Information disclosure in Microsoft's Windows Projected File System (ProjFS) component allows an authenticated local user to read files or directories that should not be accessible to them, exposing content that the access-control model intended to keep restricted. Exploitation requires the attacker to already hold a local account on the target machine (CVSS PR:L, AV:L) and does not require user interaction, and per CISA's SSVC assessment it is neither actively exploited nor automatable. Affected builds span Windows 10 21H2/22H2, Windows 11 23H2 through 26H2, and Windows Server 2019/2022/2025 including Server Core installations; no public exploit code has been identified and Microsoft has published fixes in its monthly cumulative updates, so real-world urgency is low and remediation is a routine patch cycle.
Local tampering with Windows Modern Device Management (MDM) is possible for an authenticated low-privileged attacker on affected Windows builds, allowing modification of MDM-related state or policy with high integrity impact but no confidentiality or availability impact. The CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N) confirms local access, low complexity, low privileges, no user interaction, and a medium 5.5 score; SSVC rates exploitation as none and non-automatable, and no public exploit has been identified at time of analysis. Vendor patches are available per Microsoft advisory, and affected platforms include Windows 10, Windows 11, and Windows Server releases listed in the Microsoft update guide.
Local authenticated attackers holding only low-level user privileges on a Windows host can cause the Device Association Service to misinterpret a resource's type (CWE-843 type confusion) and thereby leak sensitive information from the affected system. The flaw carries a CVSS 3.1 score of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), meaning it cannot be triggered remotely or by an unauthenticated user and does not by itself yield code execution, tampering, or denial of service, and there is no public exploit identified at time of analysis. Microsoft has shipped vendor fixes, and CISA's SSVC assessment records exploitation as none and the issue as non-automatable, so this is a moderate-priority patching and hardening item rather than an urgent, actively exploited threat.
Information disclosure in the Windows Win32 Kernel Subsystem stems from a time-of-check time-of-use (TOCTOU) race condition (CWE-367) that lets a local attacker with existing low-privileged code execution leak kernel memory contents. The issue rates only CVSS 4.7 (AV:L/AC:H/PR:L/UI:N, C:H/I:N/A:N) because seizing the narrow check-to-use window is difficult and non-deterministic; CISA's SSVC assessment scores Exploitation as 'none' and Automatable as 'no', and no public exploit code has been identified at time of analysis. Every in-support Windows 10, Windows 11 (21H2 through 26H2) and Windows Server 2012 through 2025 build below its respective patched build number is affected, and Microsoft has published fixes via its update guide.
Information disclosure in Windows Management Instrumentation (WMI) allows an authenticated local attacker to read past the end of an intended buffer, potentially exposing sensitive data held in the memory of the WMI service. The flaw affects a wide span of Windows builds - Windows 10 (1607, 1809, 21H2, 22H2), Windows 11 (23H2 through 26H2, including 26H1), and Windows Server 2012, 2012 R2, 2016, 2019, 2022 and 2025, including Server Core installations - and requires the attacker to already hold a low-privileged local session on the host (CVSS 3.1 5.5, AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Impact is confidentiality-only: no data modification, no denial of service, and no remote or unauthenticated path is indicated by the assessed vector. No public exploit code has been identified at time of analysis, CISA's SSVC assessment records exploitation as none and automatable as no, and Microsoft has released fixed builds for the affected branches.
Local information disclosure in Windows Modern Device Management (MDM) lets an authenticated, low-privileged attacker who already holds a foothold on the host read residual memory contents returned by the MDM subsystem. Rated CVSS 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), this is a local-only, low-complexity, no-user-interaction bug whose sole impact is confidentiality loss - there is no integrity or availability effect and no scope change. Vendor patches are available and no public exploit code has been identified at time of analysis; CISA's SSVC assessment records exploitation as none, automatable as no, and technical impact as partial, which places this in the moderate-priority patch cycle rather than the emergency one.
Information disclosure in Windows Win32k permits a local, authenticated attacker with a standard user session to read kernel memory contents that should be inaccessible, potentially exposing sensitive data. Affected systems include unpatched Windows 10 21H2/22H2/1809, Windows 11 23H2, and Windows Server 2019, 2022, and 2025 builds prior to the listed fixed versions; the flaw is a buffer over-read (CWE-126) requiring local access (AV:L) and low privileges (PR:L), with no remote vector and no user interaction. Vendor patches are available, and no public exploit has been identified at time of analysis; risk is moderate and low-priority despite the CVSS 5.5 base score because confidentiality impact is high but integrity and availability are unaffected.
An out-of-bounds read in the WebDAV functionality of Microsoft Windows allows a locally authenticated, low-privileged attacker to read memory contents and disclose information; exploitation requires existing local access to the host (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, base 5.5), with no user interaction and low complexity. Affected systems span Windows 10, Windows 11 (23H2 through 26H2) and Windows Server 2012 through 2025, including Server Core installations, per the EUVD-listed build ranges. There is no CISA KEV entry and no public exploit identified at time of analysis (SSVC: Exploitation none, Automatable no), so this is a moderate, not urgent, priority best characterized as a post-compromise or malicious-insider information-disclosure aid rather than an initial-access vector.
An out-of-bounds read in the Remote Desktop Display Driver component of Microsoft Windows lets an authenticated, low-privileged local attacker disclose potentially sensitive memory contents on the affected host. Exploitation requires the attacker to already hold a local foothold on the machine (AV:L, PR:L) and to execute code that reaches the driver; no user interaction is needed (UI:N), and the impact is limited to confidentiality (C:H, I:N, A:N) with no code execution or system compromise by itself. No public exploit code has been identified at time of analysis, the flaw is not in CISA KEV, and CISA's SSVC framework rates it non-automatable with only partial technical impact, so real-world urgency is LOW despite the high confidentiality rating.
Improper access control in the Windows Routing and Remote Access Service (RRAS) allows an authenticated local attacker holding only low-level privileges to tamper with service state or configuration on affected Windows 10, Windows 11, and Windows Server builds. Exploitation is strictly local (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N), requires the optional RRAS role to be installed and enabled, and impacts integrity only - confidentiality and availability are unaffected, which is consistent with the moderate 5.5 base score. There is no public exploit identified at time of analysis and no evidence of confirmed active exploitation (CISA KEV), and vendor-released patches are available for every affected build branch.
Missing authorization in the Windows Overlay Filter (WOF) allows an authenticated local attacker to tamper with protected file/overlay data on affected Windows 10, Windows 11, and Windows Server 2016-2025 systems, producing an integrity-only impact (CVSS 5.5, CWE-862). The assessed vector (AV:L/PR:L/UI:N, C:N/I:H/A:N) means exploitation is neither remote nor unauthenticated: an attacker must already hold low-privileged local execution on the host, which confines real-world exposure to post-compromise and malicious-insider scenarios rather than a pre-auth or network attack. CISA SSVC records exploitation as "none" and no public exploit code has been identified at time of analysis; vendor patches are available from Microsoft, and this is a moderate-severity, low-urgency issue rather than an emergency.
An out-of-bounds read in the Windows Audio Service (Audiosrv) allows an attacker who already holds authenticated local access with low-level privileges to disclose memory contents from the affected host. The flaw is rated CVSS 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), meaning it is strictly a local, post-compromise information-disclosure issue - there is no remote vector, no integrity or availability impact, and no code execution. No public exploit code has been identified at time of analysis, and CISA's SSVC assessment records no exploitation activity and marks the issue as not automatable, so this is a genuine but low-urgency issue that should be handled through routine patching rather than emergency response.
Local tampering of network list data in the Windows Network List Service allows an authenticated low-privileged attacker to modify network profiles and settings, resulting in partial integrity impact while confidentiality and availability remain unaffected. Affected versions span Windows 10, Windows 11, and numerous Windows Server releases, with vendor patches available. No public exploit identified at time of analysis, and given the required local access and lack of remote vector, the risk is assessed as a moderate, low-priority integrity issue.
Uncontrolled resource consumption in the Windows RPC Endpoint Mapper service (listening on TCP 135) allows an unauthenticated, remote attacker to deny service over a network by exhausting service resources. Rated CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H), the impact is availability-only and the High attack complexity means an outage is not achievable with a single trigger against default configurations, but requires sustained or precisely timed request volume. The affected surface spans Windows Server 2012 through Server 2025 (including Server Core) plus Windows 10 1607/1809/21H2/22H2 and Windows 11 23H2 through 26H2; no public exploit code and no confirmed active exploitation have been identified at time of analysis, and Microsoft has published a vendor update guide.
Information disclosure in Windows Kernel-Mode Drivers lets an authenticated local attacker read uninitialized kernel memory and leak residual kernel data on affected Windows 10, Windows 11, and Windows Server builds (Windows Server 2012 R2 through 2025). Exploitation requires a pre-existing standard local account and the ability to invoke the vulnerable driver code path; it is not remotely triggerable, needs no user interaction, and provides no code execution or system modification, so realistic value is as a kernel-memory-leak primitive inside a larger exploit chain. No public exploit code or confirmed active exploitation has been identified at time of analysis, and CISA SSVC rates the issue non-automatable, consistent with its low-to-moderate priority despite the CVSS 5.5 Medium score.
Local integrity tampering in the Windows Update Stack allows an authenticated low-privilege attacker who already holds a session on an affected Windows host to modify update-related configuration or state that should be protected, producing a high integrity impact with no confidentiality or availability effect. The flaw (CWE-15, external control of a system or configuration setting) touches a broad set of Windows 10, Windows 11, and Windows Server branches from 1809/21H2 through 26H1/26H2 and Server 2019/2022/2025. Vendor patches are available, no public exploit code or active exploitation has been identified, and CISA's SSVC assessment records exploitation as none with the issue rated non-automatable, so real-world risk is largely confined to insiders or post-compromise tampering rather than scalable remote attacks.
Information disclosure in the Windows Event Log service allows an authenticated local attacker to read potentially sensitive memory contents. Affecting a broad range of Windows 10, 11, and Server editions, this low-severity flaw requires prior local access and only results in confidentiality impact, with no code execution or privilege escalation. No public exploit identified at time of analysis, and Microsoft has released patches.
An out-of-bounds read in the Microsoft Windows Storage Port Driver (CWE-125) lets an attacker who already has physical access to a device read past the end of a buffer and disclose kernel memory contents to an unauthorized party. Every supported Windows client and server build from Windows 10 1607 and Windows Server 2012 through Windows 11 26H2 and Windows Server 2025 is affected, as tracked in EUVD-2026-100340, and because the vector is AV:P the flaw cannot be reached remotely - it is confined to lost, stolen, or unattended hardware and evil-maid style scenarios. Microsoft has released a vendor patch, there is no public exploit identified at time of analysis, and CISA's SSVC decision framework rates exploitation as none and the issue as non-automatable, making this a genuinely low-priority item despite the CVSS confidentiality rating of High.
Improper authorization in the Windows Encrypting File System (EFS) lets an already-logged-in local user tamper with protected data that they should not be permitted to modify, yielding a high integrity impact with no confidentiality or availability impact (CVSS 5.5, AV:L/PR:L/UI:N, C:N/I:H/A:N). Only Windows 10, Windows 11, and Windows Server hosts that have not yet applied the current cumulative updates are exposed; the attack is strictly local, requires an interactive session and at least low-level privileges, and there is no public exploit identified at time of analysis (no CISA KEV entry, SSVC exploitation: none, EPSS not notable). This is a genuinely moderate, low-urgency issue rather than a high-priority emergency: vendor patches already exist for every affected build, so exposure is limited to unpatched systems where a low-privileged local user could subvert EFS authorization checks.
An out-of-bounds read (CWE-125) in Microsoft Digest Authentication on unpatched Windows client and server builds lets an authenticated local user disclose information from the host; the CVSS 3.1 vector (AV:L/PR:L/UI:N/S:U/C:H/I:N/A:N) confirms the attacker must already hold low-level privileges on the machine, needs no user interaction, and can only read data - with no impact on integrity or availability. Because reachability is local rather than remote, the component is the Windows Digest/SASL authentication provider itself, and exploitation is limited to memory disclosure on systems that have not yet installed the vendor fixes identified by EUVD build numbers. No public exploit code has been identified at time of analysis, there is no CISA KEV listing, and SSVC assesses the issue as not automatable with no observed exploitation, so it should be treated as a low-to-moderate-priority hardening item rather than an emergency.
An out-of-bounds read in the Windows Key Storage Provider (KSP) allows an authenticated, low-privileged local user to disclose memory contents from the calling process, as rated CVSS 3.1 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only systems running Windows builds below the fixed levels published in the Microsoft update guide and EUVD (for example, Windows 11 24H2 below 10.0.26100.9711 or Windows Server 2025 below 10.0.26100.33650) are affected; patched builds are not exploitable. The issue requires an existing local session and valid credentials, is not remotely reachable, and there is no public exploit identified at time of analysis; CISA's SSVC assessment rates exploitation as none and automatable as no, making this a moderate-severity, low-priority issue in practice.

Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Actively exploited in the wild (cisa kev) and EPSS exploitation probability 78.1%.
An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds low-level authorization on the network send crafted DNS requests that cause the service to read past the end of an allocated buffer, potentially returning memory contents to the attacker (CVSS 6.5, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only hosts actually running the DNS Server role - typically domain controllers and dedicated DNS servers rather than standard workstations - are exposed, and exploitation requires the PR:L authorization the assessed vector specifies, so this is not an unauthenticated flaw. Impact is limited to confidentiality disclosure with no integrity or availability effect; no public exploit has been identified at time of analysis, and a vendor patch is available from Microsoft.
An out-of-bounds read in the Windows DNS Server role lets an authorized, authenticated attacker send a crafted DNS request that causes the service to read past the end of an allocated buffer and return information it should not disclose over the network. Exploitation requires the DNS Server role to be installed and reachable, and the attacker must already hold a low-privileged position able to send requests to the DNS service (CVSS PR:L, unauthenticated access is not sufficient per the assessed vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N); there is no integrity or availability impact, and no user interaction is required. Only Windows client and server builds running the DNS Server role below the patched versions listed in the EUVD data are affected; no public exploit identified at time of analysis, and this is assessed as a moderate authenticated information-disclosure flaw rather than a top-tier emergency.
Information disclosure in Microsoft Windows DNS Server is caused by an out-of-bounds read that a low-privileged, authenticated attacker can trigger over the network to leak memory contents from an affected unpatched system. The issue affects DNS components in Windows Server 2012 through 2025 and Windows 10/11, and exploitation requires network reachability plus authorized low-privilege access as reflected by CVSS PR:L and UI:N. Vendor patches are available, and no public exploit was identified at time of analysis; this is a moderate information-disclosure issue rather than a critical remote-code-execution emergency.
Out-of-bounds read in the Windows DNS Server role lets an attacker who holds low-level authorization (authenticated, PR:L) disclose server memory contents over the network, giving a high confidentiality impact with no integrity or availability effect (CVSS 6.5, CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only Windows hosts that have the DNS Server role installed and reachable over the network are exposed; the flaw lives in that role's request-parsing path, so Windows systems without the role are not affected, and EUVD enumerates the vulnerable build ranges across Windows 10, Windows 11, and Windows Server 2012 through 2025. There is no confirmed active exploitation (CISA KEV) and no public exploit identified at time of analysis, while a vendor patch is available per the Microsoft advisory.
An out-of-bounds read in the Windows DNS Server role allows an attacker who already holds low-level authorization on or toward the target to read beyond the bounds of an allocated buffer and disclose server memory over the network (CVSS 6.5, CWE-125, PR:L). Only hosts running the DNS Server role are in scope - domain controllers and dedicated DNS servers on Windows Server 2012 through 2025 and supported Windows 10/11 builds - so the network vector does not translate into an anonymous internet-wide attack. Microsoft has published vendor updates for the affected builds, and no public exploit identified at time of analysis; impact is confidentiality-only, with no integrity or availability effect.
Information disclosure in the Windows DNS Server role allows a remote attacker holding valid low-privilege credentials (CVSS PR:L) to read out-of-bounds memory by sending a crafted DNS request, leaking data over the network with high confidentiality impact but no integrity or availability effect. Only pre-patch Windows Server and Windows 10/11 builds with the DNS Server role installed and reachable are affected, and exploitation requires that the attacker can already query or reach the DNS service rather than being an anonymous internet-wide attacker. There is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis, though the vendor has released a patch and the flaw carries a moderate CVSS base score of 6.5.
Memory disclosure via an out-of-bounds read in the Windows DNS Server service allows a remote, authenticated low-privilege attacker to leak server process memory over the network. Affected deployments are Windows Server 2012 through Windows Server 2025 (including Server Core) and Windows 10/11 builds running the DNS Server role that have not been updated to the fixed builds listed by Microsoft; no public exploit identified at time of analysis. The assessed impact is information disclosure only (CVSS 6.5, C:H/I:N/A:N) with no code execution or denial of service, but leaked memory may expose sensitive data that aids follow-on attacks.
Out-of-bounds read in the Microsoft Windows DNS Server role lets an authenticated, low-privileged attacker reachable over the network read past the end of a buffer and disclose information from server memory, rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). The flaw affects a broad set of Windows client and server builds running the DNS Server role, enumerated by EUVD-2026-100438, and exposure is limited to confidentiality - integrity and availability are unaffected and no user interaction is required. There is no CISA KEV listing and no public exploit identified at time of analysis; the PR:L vector means the attacker must already hold low-level credentials, which constrains opportunistic mass exploitation, and vendor patches are available.
An out-of-bounds read in the Windows DNS Server role allows an authenticated attacker with low-level privileges to disclose sensitive information over the network. This medium-severity (CVSS 6.5) flaw affects many Windows Server and Windows client versions when the DNS Server role is installed, including Windows Server 2012 through 2025 and Windows 10/11 builds prior to the fixed versions listed in Microsoft’s advisory. No public exploit code or active exploitation has been identified at time of analysis, and a vendor patch is available.
Information disclosure in the Windows DNS Server role allows an authenticated, low-privilege network attacker to trigger an out-of-bounds read that leaks memory contents in responses. Tracked as CVE-2026-97835 (CVSS 6.5, CWE-125, C:H/I:N/A:N), it affects the DNS Server component across Windows 10, Windows 11, and Windows Server 2012 through 2025, but only on hosts where the DNS Server role is actually installed and reachable - typically domain controllers and dedicated DNS hosts in Active Directory environments. Exploitation requires low-privilege credentials (PR:L via CVSS:3.1/AV:N/AC:L/PR:L/UI:N), not fully anonymous access, and the outcome is limited to confidentiality loss with no code execution, tampering, or denial of service. Vendor patching is available from Microsoft and no public exploit code or confirmed active exploitation was identified at time of analysis.
An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds valid low-level credentials on the network cause the service to read past the bounds of a memory buffer, disclosing sensitive information over the network. This is a medium-severity (CVSS 6.5) information-disclosure flaw rated AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N - exploitation requires a reachable, running DNS Server role (typically on domain controllers or dedicated DNS hosts) and at least low-level authorization, but needs no user interaction and has low attack complexity. The privilege prerequisite narrows the attacker population and the impact is confined to confidentiality: there is no code execution, integrity, or availability impact, and no public exploit identified at time of analysis. A vendor patch is available.
Information disclosure in the Windows DNS Server role allows a network-positioned attacker holding a low level of authorization (CVSS PR:L, described by Microsoft as an 'authorized attacker') to trigger an out-of-bounds read and leak data from server memory. The issue is rated CVSS 6.5 with confidentiality impact only and no integrity or availability effect, and it affects a wide range of unpatched Windows Server and Windows client builds that enable the DNS Server role, from Windows Server 2012 through Windows Server 2025 plus Windows 10 and Windows 11 releases. No public exploit code has been identified at time of analysis, there is no CISA KEV listing indicating active exploitation, and Microsoft has published a patched update; systems already at the fixed build numbers in the vendor advisory are not affected.
Information disclosure in the Windows DNS Server role lets an authenticated, low-privileged attacker read past the bounds of an allocated buffer and leak memory contents over the network. The flaw (CWE-125, out-of-bounds read) affects a broad set of Windows Server builds - Server 2012, 2012 R2, 2016, 2019, 2022 and 2025, including Server Core installations - plus Windows 10 (1607, 1809, 21H2, 22H2) and Windows 11 (23H2, 24H2, 25H2, 26H1, 26H2), and only exposed systems that have the DNS Server role installed and reachable. Impact is limited to confidentiality (CVSS 6.5, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) with no integrity or availability effect; no public exploit has been identified at time of analysis, and vendor-released patches are available per the Microsoft advisory.
An out-of-bounds read (CWE-125) in the Windows DNS Server role allows a remote attacker holding some level of valid privilege (CVSS PR:L) to leak server memory contents over the network, resulting in information disclosure only. Successful exploitation requires network reachability to a DNS Server host and prior access to the DNS service - it is not anonymously exploitable from the internet - while no user interaction (UI:N) and only low attack complexity (AC:L) are needed. The confidentiality impact is rated High but integrity and availability are unaffected, and no public exploit code or confirmed active exploitation has been identified at time of analysis; vendor patches are available, making this a genuine but moderate-priority issue rather than an emergency.
An out-of-bounds read in Microsoft's Windows DNS Server role lets an attacker who already holds low-level authorized network access (PR:L) leak process memory across the network, producing a high confidentiality impact with no integrity or availability effect. Exploitation is limited to hosts where the DNS Server role is installed and reachable, and the authentication prerequisite rules out anonymous internet-wide attacks, so the issue is rated CVSS 6.5 and treated as moderate rather than emergency priority. No public exploit code and no confirmed active exploitation (CISA KEV) were identified in the available intelligence, though vendor patches are available for all affected branches.
Information disclosure in Windows DNS Server allows an authenticated attacker with low privileges to read sensitive memory contents over the network. This buffer over-read affects numerous Windows Server and Windows client versions, including Server 2012 through 2025 and Windows 10/11 builds. No public exploit has been identified at time of analysis, and vendor patches are available.
An out-of-bounds read (CWE-125) in the Windows DNS Server service lets an attacker who already holds low-level credentials read beyond a buffer and disclose in-memory information over the network, rated CVSS 6.5 with a confidentiality-only impact and no effect on integrity or availability. Exploitation requires authentication (CVSS PR:L), network reachability to a host actually running the DNS Server role, and low attack complexity with no user interaction, so this is a moderate-priority authenticated information-disclosure flaw rather than a pre-authentication remote code execution issue. Affected systems span Windows Server 2012 through Server 2025 (including Server Core installs) and several Windows 10 and Windows 11 client releases; Microsoft has published a fix through its update guide, and no public exploit code was identified at time of analysis.
Information disclosure in the Microsoft Windows DNS Server role lets an authenticated, network-positioned attacker trigger an out-of-bounds read and retrieve memory contents over the network. The flaw (CWE-125) affects a wide span of Windows builds where the DNS Server role is installed and running - Windows Server 2012, 2012 R2, 2016, 2019, 2022 and 2025, plus Windows 10 (1607-22H2) and Windows 11 (23H2 through 26H2) - and requires only low-privilege access (CVSS:3.1/AV:N/AC:L/PR:L/UI:N with C:H/I:N/A:N, base 6.5) with no user interaction; impact is confined to confidentiality, with no integrity or availability effect. There is no public exploit code identified at time of analysis and the issue is not listed on CISA KEV, but Microsoft has published vendor fixes, so patching priority is driven by the sensitivity of data exposed by DNS infrastructure rather than by observed exploitation.
An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds authorized access to the DNS service (CVSS PR:L) disclose memory contents over the network, with no user interaction required (UI:N) and low attack complexity (AC:L). Impact is strictly confidentiality (C:H/I:N/A:N) - there is no code execution, data modification, or denial of service, and only Windows and Windows Server builds with the DNS Server role enabled are exposed. This is a genuine but moderate-priority issue rather than a top-tier emergency: CISA SSVC records Exploitation as 'none' and Automatable as 'no', and no public exploit code has been identified at time of analysis, though a vendor patch is available.
Out-of-bounds read in Windows DNS Server allows authenticated remote attackers with low-level privileges (PR:L) to disclose sensitive information from process memory over the network. Affected versions include Windows Server 2012 through 2025 and various Windows 10/11 builds hosting the DNS Server role, as detailed in the EUVD advisory. Vendor patches are available, and no public exploit code or active exploitation is identified at time of analysis; the CVSS score of 6.5 reflects high confidentiality impact but requires prior authentication, making this a moderate-priority issue.
Out-of-bounds read in Windows DNS Server allows an authenticated, low-privileged attacker to disclose sensitive memory contents over the network, affecting Windows Server 2012 through Server 2025 and Windows 10/11 systems that have the DNS Server role enabled. The flaw is rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), is a CWE-125 read-only disclosure with no integrity or availability impact, and has no public exploit identified at time of analysis; vendor patches are available.
An out-of-bounds read in the Microsoft Windows DNS Server service lets an authorized, network-positioned attacker cause the server to read past the bounds of an allocated buffer and return the resulting memory contents within DNS responses (CVSS 3.1 base 6.5, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only hosts that have the DNS Server role installed and running on unpatched Windows 10, Windows 11, or Windows Server builds are affected; the PR:L requirement means the actor must already be authorized to submit queries or data that reach the vulnerable parser, so anonymous Internet clients are not sufficient. Impact is limited to information disclosure of server memory with no integrity or availability effect, and no public exploit identified at time of analysis. Microsoft has released updates that raise each affected build to a fixed revision.
Information disclosure in the Microsoft Windows DNS Server role allows an authenticated, low-privileged attacker to trigger an out-of-bounds read and leak memory contents over the network. The flaw affects Windows Server 2012 through Server 2025 as well as multiple Windows 10 and Windows 11 builds, and carries a CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), so impact is confined to confidentiality with no integrity or availability effect and no code execution or denial of service implied. Vendor-released patches exist as fixed build numbers per the EUVD data and the MSRC advisory, and no public exploit identified at time of analysis (no KEV or POC signal in the provided intelligence).
An out-of-bounds read in the Windows DNS Server role lets an attacker who already holds low-level authorization on the network read memory beyond intended buffer boundaries and disclose that information over the network. Only hosts running the DNS Server role are affected, spanning Windows Server 2012 through 2025 (including Server Core installations) plus Windows 10 and Windows 11 clients that host the role; exploitation requires an authenticated/authorized position (CVSS PR:L) with network reachability to the DNS service, so it is not an unauthenticated remote flaw. Impact is limited to confidentiality (C:H) with no integrity or availability effect, and no public exploit code has been identified at time of analysis - the practical risk concentrates in environments where low-privilege accounts or internal footholds can reach a DNS server.
An out-of-bounds read (CWE-125) in the Microsoft Windows DNS Server role allows an attacker holding low-privilege authenticated access to disclose information over the network. Only hosts actually running the DNS Server role are exposed; the flaw is rated CVSS 6.5 with high confidentiality impact but no integrity or availability impact, and exploitation requires authorized (PR:L) rather than unauthenticated network access. Patched builds are available from the vendor per the MSRC update guide, and no public exploit code or active exploitation has been identified at time of analysis.
Heap-based buffer overflow in Windows DNS Server allows an authenticated, low-privilege attacker with network access to disclose sensitive information from server memory. The vulnerability affects numerous Windows Server and Windows 10/11 builds that have the DNS Server role installed, with no public exploit identified at time of analysis. Although rated CVSS 6.5 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, the confidentiality-only impact and requirement for authentication limit the realistic threat to information leakage rather than code execution or denial of service.
Heap memory disclosure in Microsoft Windows Hyper-V lets an authenticated, low-privileged principal - such as an account inside a guest VM or a low-rights user able to reach the Hyper-V service over the network - read leaked contents of the hypervisor's heap, affecting Windows 10, Windows 11 (23H2 through 26H2), and Windows Server 2019, 2022, and 2025 including Server Core installations. The flaw carries a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), meaning no user interaction and low attack complexity are required, but the attacker must already hold valid credentials and the outcome is read-only: confidentiality is fully impacted while integrity and availability are untouched, so hosts without the Hyper-V role enabled are not exposed. No public exploit been identified at time of analysis, and Microsoft has published fixed builds via its MSRC update guide.
Local information disclosure in the Windows Client Side Caching driver (csc.sys) lets an authenticated attacker who already holds low-level privileges on a Windows host read sensitive data that should be restricted, such as contents of the Offline Files cache. The flaw affects default installations across Windows 10 (1607 through 22H2), Windows 11 (23H2 through 26H2), and Windows Server 2012 through 2025, and requires only local access with no user interaction (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, base 5.5). There is no public exploit identified at time of analysis, CISA's SSVC rates exploitation as 'none' and the issue as non-automatable with partial technical impact, and Microsoft has released patched builds - making this a post-compromise disclosure primitive rather than a remote entry point.
Local privilege escalation in the Windows Distributed File System (DFS) lets an authenticated attacker with valid host credentials trigger a heap-based buffer overflow (CWE-122) and elevate to SYSTEM on unpatched Windows 10, Windows 11, and Windows Server builds. Exploitation is local only with no user interaction and, per Microsoft's advisory, requires existing high privileges, so realistic exposure is limited to shared, multi-user, or terminal-server hosts where an untrusted authenticated principal is present. No public exploit code has been identified at time of analysis and CISA's SSVC rates exploitation as none; vendor patches are available.
Information disclosure in the Windows NTFS file system driver allows an authenticated local attacker to read sensitive system information that should be restricted to a higher privilege level. The flaw affects Windows 10, Windows 11, and Windows Server installations on NTFS volumes below their respective patched builds; exploitation requires pre-existing local code execution or interactive access as a low-privileged user (CVSS PR:L), with no remote vector and no user interaction (UI:N). No public exploit code has been identified at time of analysis, and Microsoft has released vendor patches.
An out-of-bounds read in the Windows Universal Disk Format File System (UDFS) kernel-mode driver lets a locally authenticated attacker disclose information - potentially kernel memory contents - on an affected host. Exploitation requires existing local access and the ability to feed crafted UDF-formatted content (a mounted ISO/UDF image, removable USB media, or a virtual volume) to the driver; the vulnerability is not remotely reachable, cannot be triggered unauthenticated, and has no integrity or availability impact, which is why CISA's SSVC rates it non-exploited and non-automatable. Microsoft has shipped fixed builds for every affected Windows 10, Windows 11, and Windows Server release, and no public exploit code has been identified at time of analysis, making this a moderate-severity, low-priority issue despite affecting a kernel-mode component present by default on all listed platforms.
An out-of-bounds read in the Windows NTFS file system driver (ntfs.sys) lets an authenticated local user with low privileges read memory contents beyond an allocated buffer, resulting in local information disclosure (CWE-125, CVSS 3.1 5.5). Only hosts that have not applied Microsoft's current cumulative updates are affected; the EUVD data lists a broad range of client and server branches below their respective fixed builds (?fix versions include Windows 11 23H2 10.0.22631.7652, 24H2 10.0.26100.9711, 25H2 10.0.26200.9711, Windows 10 1607/Server 2016 10.0.14393.9612, and Windows 10 1809/Server 2019 10.0.17763.9376). There is no remote vector and CISA SSVC rates the flaw as non-automatable with only partial technical impact, and no public exploit code has been identified at time of analysis, so this is a genuine but low-priority disclosure primitive rather than a path to privilege escalation.
Information disclosure in the Microsoft Windows NTFS filesystem driver allows a local, low-privileged, authenticated attacker to read portions of kernel memory by triggering an integer underflow (wraparound) during a crafted NTFS operation, with no user interaction required. Exploitation is confined to the local attack vector (CVSS:3.1/AV:L/AC:L/PR:L/UI:N) and yields confidentiality impact only (C:H/I:N/A:N, score 5.5) - there is no write, code-execution, or denial-of-service effect, and CISA's SSVC analysis rates the issue as not automatable with no known exploitation. No public exploit code has been identified at time of analysis, and Microsoft has released a vendor patch covering all affected Windows client and server builds.
Information disclosure in Windows Message Queuing (MSMQ) Queue Manager allows an authenticated local attacker to read data from an affected host via a type confusion flaw. Exploitation requires the optional MSMQ feature to be installed and the Queue Manager service running (not enabled by default), and impact is limited to confidentiality with no code execution or privilege escalation. Microsoft has released patches; no public exploit or active exploitation has been identified at time of analysis.
Local information disclosure in the Microsoft Windows Search Component lets an authenticated low-privileged user read out-of-bounds memory contents on the affected host, giving a post-foothold attacker a confidentiality-only leak (CVSS 5.5, AV:L/PR:L/UI:N/S:U/C:H/I:N/A:N) with no integrity or availability impact. Every current Windows client and server branch is affected - Windows 10 1607/1809/21H2/22H2, Windows 11 23H2/24H2/25H2/26H1/26H2, and Windows Server 2012 through 2025 including Server Core - so the exposure is broad even though the flaw cannot be used for remote initial access. No public exploit identified at time of analysis: CISA SSVC records Exploitation: none and Automatable: no, CISA KEV does not list this CVE, and no EPSS signal was provided; urgency is driven by patch hygiene rather than active threat activity. Microsoft has released fixes (see the MSRC update guide referenced below).
Information disclosure in the Windows Secure Kernel Mode component lets a locally authenticated attacker with low privileges read sensitive system information that should remain isolated inside the hypervisor-protected secure kernel, affecting Windows 10, Windows 11 and Windows Server 2016 through 2025 builds that predate Microsoft's fixed versions. Exploitation is constrained by high attack complexity and state-dependent conditions (CVSS AC:H, PR:L, AV:L), and there is no public exploit identified at time of analysis; CISA's SSVC assessment rates exploitation as none, the attack as non-automatable, and technical impact as partial. Microsoft has released patches, so this is a moderate-priority hardening item rather than an emergency response.
Information disclosure in the Windows USB Print Driver allows a locally authenticated, low-privilege attacker to read beyond intended buffer boundaries and leak contents of driver memory on affected Windows 10, Windows 11, and Windows Server builds (2012 through 2025, including Server Core installations). Exploitation requires an existing foothold on the host with the ability to exercise the USB print driver code path (CVSS:3.1/AV:L/AC:L/PR:L/UI:N), needs no victim interaction, and is limited to confidentiality impact - no data modification, no denial of service, and no remote vector. No public exploit code has been identified at time of analysis, CISA's SSVC assessment records exploitation as 'none' with partial technical impact, and an EUVD record (EUVD-2026-99784) tracks the same affected build list; vendor patches are available, making this a genuine but lower-tier patching priority compared with remotely reachable issues.
Out-of-bounds read in Windows Imaging Component (WIC) allows a locally authenticated attacker to disclose in-process memory contents when WIC processes a crafted or attacker-influenced image, with a CVSS of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Affected systems include a broad set of supported Windows 10, Windows 11, and Windows Server builds below their patched build thresholds, and exploitation requires prior low-privileged access to the host rather than remote network reachability. No public exploit identified at time of analysis, CISA SSVC reports exploitation none and automatable no, and Microsoft has released vendor updates to address the flaw.
Local tampering with Windows Security Account Manager (SAM) data is possible on unpatched Windows hosts because a critical SAM function performs no authentication or authorization check, letting an authenticated local user modify integrity-sensitive account information. Exploitation requires a pre-existing local session (AV:L, PR:L) and affects only integrity (C:N/A:N), so the practical impact is moderate rather than catastrophic, and no public exploit identified at time of analysis - SSVC rates exploitation as none and automatable as no. The flaw spans Windows 10 21H2/22H2, Windows 11 23H2 through 26H2, and Windows Server 2022/2025 (including Server Core), all of which have vendor fixes available.
Information disclosure in Microsoft's Windows Projected File System (ProjFS) component allows an authenticated local user to read files or directories that should not be accessible to them, exposing content that the access-control model intended to keep restricted. Exploitation requires the attacker to already hold a local account on the target machine (CVSS PR:L, AV:L) and does not require user interaction, and per CISA's SSVC assessment it is neither actively exploited nor automatable. Affected builds span Windows 10 21H2/22H2, Windows 11 23H2 through 26H2, and Windows Server 2019/2022/2025 including Server Core installations; no public exploit code has been identified and Microsoft has published fixes in its monthly cumulative updates, so real-world urgency is low and remediation is a routine patch cycle.
Local tampering with Windows Modern Device Management (MDM) is possible for an authenticated low-privileged attacker on affected Windows builds, allowing modification of MDM-related state or policy with high integrity impact but no confidentiality or availability impact. The CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N) confirms local access, low complexity, low privileges, no user interaction, and a medium 5.5 score; SSVC rates exploitation as none and non-automatable, and no public exploit has been identified at time of analysis. Vendor patches are available per Microsoft advisory, and affected platforms include Windows 10, Windows 11, and Windows Server releases listed in the Microsoft update guide.
Local authenticated attackers holding only low-level user privileges on a Windows host can cause the Device Association Service to misinterpret a resource's type (CWE-843 type confusion) and thereby leak sensitive information from the affected system. The flaw carries a CVSS 3.1 score of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), meaning it cannot be triggered remotely or by an unauthenticated user and does not by itself yield code execution, tampering, or denial of service, and there is no public exploit identified at time of analysis. Microsoft has shipped vendor fixes, and CISA's SSVC assessment records exploitation as none and the issue as non-automatable, so this is a moderate-priority patching and hardening item rather than an urgent, actively exploited threat.
Information disclosure in the Windows Win32 Kernel Subsystem stems from a time-of-check time-of-use (TOCTOU) race condition (CWE-367) that lets a local attacker with existing low-privileged code execution leak kernel memory contents. The issue rates only CVSS 4.7 (AV:L/AC:H/PR:L/UI:N, C:H/I:N/A:N) because seizing the narrow check-to-use window is difficult and non-deterministic; CISA's SSVC assessment scores Exploitation as 'none' and Automatable as 'no', and no public exploit code has been identified at time of analysis. Every in-support Windows 10, Windows 11 (21H2 through 26H2) and Windows Server 2012 through 2025 build below its respective patched build number is affected, and Microsoft has published fixes via its update guide.
Information disclosure in Windows Management Instrumentation (WMI) allows an authenticated local attacker to read past the end of an intended buffer, potentially exposing sensitive data held in the memory of the WMI service. The flaw affects a wide span of Windows builds - Windows 10 (1607, 1809, 21H2, 22H2), Windows 11 (23H2 through 26H2, including 26H1), and Windows Server 2012, 2012 R2, 2016, 2019, 2022 and 2025, including Server Core installations - and requires the attacker to already hold a low-privileged local session on the host (CVSS 3.1 5.5, AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Impact is confidentiality-only: no data modification, no denial of service, and no remote or unauthenticated path is indicated by the assessed vector. No public exploit code has been identified at time of analysis, CISA's SSVC assessment records exploitation as none and automatable as no, and Microsoft has released fixed builds for the affected branches.
Local information disclosure in Windows Modern Device Management (MDM) lets an authenticated, low-privileged attacker who already holds a foothold on the host read residual memory contents returned by the MDM subsystem. Rated CVSS 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), this is a local-only, low-complexity, no-user-interaction bug whose sole impact is confidentiality loss - there is no integrity or availability effect and no scope change. Vendor patches are available and no public exploit code has been identified at time of analysis; CISA's SSVC assessment records exploitation as none, automatable as no, and technical impact as partial, which places this in the moderate-priority patch cycle rather than the emergency one.
Information disclosure in Windows Win32k permits a local, authenticated attacker with a standard user session to read kernel memory contents that should be inaccessible, potentially exposing sensitive data. Affected systems include unpatched Windows 10 21H2/22H2/1809, Windows 11 23H2, and Windows Server 2019, 2022, and 2025 builds prior to the listed fixed versions; the flaw is a buffer over-read (CWE-126) requiring local access (AV:L) and low privileges (PR:L), with no remote vector and no user interaction. Vendor patches are available, and no public exploit has been identified at time of analysis; risk is moderate and low-priority despite the CVSS 5.5 base score because confidentiality impact is high but integrity and availability are unaffected.
An out-of-bounds read in the WebDAV functionality of Microsoft Windows allows a locally authenticated, low-privileged attacker to read memory contents and disclose information; exploitation requires existing local access to the host (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, base 5.5), with no user interaction and low complexity. Affected systems span Windows 10, Windows 11 (23H2 through 26H2) and Windows Server 2012 through 2025, including Server Core installations, per the EUVD-listed build ranges. There is no CISA KEV entry and no public exploit identified at time of analysis (SSVC: Exploitation none, Automatable no), so this is a moderate, not urgent, priority best characterized as a post-compromise or malicious-insider information-disclosure aid rather than an initial-access vector.
An out-of-bounds read in the Remote Desktop Display Driver component of Microsoft Windows lets an authenticated, low-privileged local attacker disclose potentially sensitive memory contents on the affected host. Exploitation requires the attacker to already hold a local foothold on the machine (AV:L, PR:L) and to execute code that reaches the driver; no user interaction is needed (UI:N), and the impact is limited to confidentiality (C:H, I:N, A:N) with no code execution or system compromise by itself. No public exploit code has been identified at time of analysis, the flaw is not in CISA KEV, and CISA's SSVC framework rates it non-automatable with only partial technical impact, so real-world urgency is LOW despite the high confidentiality rating.
Improper access control in the Windows Routing and Remote Access Service (RRAS) allows an authenticated local attacker holding only low-level privileges to tamper with service state or configuration on affected Windows 10, Windows 11, and Windows Server builds. Exploitation is strictly local (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N), requires the optional RRAS role to be installed and enabled, and impacts integrity only - confidentiality and availability are unaffected, which is consistent with the moderate 5.5 base score. There is no public exploit identified at time of analysis and no evidence of confirmed active exploitation (CISA KEV), and vendor-released patches are available for every affected build branch.
Missing authorization in the Windows Overlay Filter (WOF) allows an authenticated local attacker to tamper with protected file/overlay data on affected Windows 10, Windows 11, and Windows Server 2016-2025 systems, producing an integrity-only impact (CVSS 5.5, CWE-862). The assessed vector (AV:L/PR:L/UI:N, C:N/I:H/A:N) means exploitation is neither remote nor unauthenticated: an attacker must already hold low-privileged local execution on the host, which confines real-world exposure to post-compromise and malicious-insider scenarios rather than a pre-auth or network attack. CISA SSVC records exploitation as "none" and no public exploit code has been identified at time of analysis; vendor patches are available from Microsoft, and this is a moderate-severity, low-urgency issue rather than an emergency.
An out-of-bounds read in the Windows Audio Service (Audiosrv) allows an attacker who already holds authenticated local access with low-level privileges to disclose memory contents from the affected host. The flaw is rated CVSS 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), meaning it is strictly a local, post-compromise information-disclosure issue - there is no remote vector, no integrity or availability impact, and no code execution. No public exploit code has been identified at time of analysis, and CISA's SSVC assessment records no exploitation activity and marks the issue as not automatable, so this is a genuine but low-urgency issue that should be handled through routine patching rather than emergency response.
Local tampering of network list data in the Windows Network List Service allows an authenticated low-privileged attacker to modify network profiles and settings, resulting in partial integrity impact while confidentiality and availability remain unaffected. Affected versions span Windows 10, Windows 11, and numerous Windows Server releases, with vendor patches available. No public exploit identified at time of analysis, and given the required local access and lack of remote vector, the risk is assessed as a moderate, low-priority integrity issue.
Uncontrolled resource consumption in the Windows RPC Endpoint Mapper service (listening on TCP 135) allows an unauthenticated, remote attacker to deny service over a network by exhausting service resources. Rated CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H), the impact is availability-only and the High attack complexity means an outage is not achievable with a single trigger against default configurations, but requires sustained or precisely timed request volume. The affected surface spans Windows Server 2012 through Server 2025 (including Server Core) plus Windows 10 1607/1809/21H2/22H2 and Windows 11 23H2 through 26H2; no public exploit code and no confirmed active exploitation have been identified at time of analysis, and Microsoft has published a vendor update guide.
Information disclosure in Windows Kernel-Mode Drivers lets an authenticated local attacker read uninitialized kernel memory and leak residual kernel data on affected Windows 10, Windows 11, and Windows Server builds (Windows Server 2012 R2 through 2025). Exploitation requires a pre-existing standard local account and the ability to invoke the vulnerable driver code path; it is not remotely triggerable, needs no user interaction, and provides no code execution or system modification, so realistic value is as a kernel-memory-leak primitive inside a larger exploit chain. No public exploit code or confirmed active exploitation has been identified at time of analysis, and CISA SSVC rates the issue non-automatable, consistent with its low-to-moderate priority despite the CVSS 5.5 Medium score.
Local integrity tampering in the Windows Update Stack allows an authenticated low-privilege attacker who already holds a session on an affected Windows host to modify update-related configuration or state that should be protected, producing a high integrity impact with no confidentiality or availability effect. The flaw (CWE-15, external control of a system or configuration setting) touches a broad set of Windows 10, Windows 11, and Windows Server branches from 1809/21H2 through 26H1/26H2 and Server 2019/2022/2025. Vendor patches are available, no public exploit code or active exploitation has been identified, and CISA's SSVC assessment records exploitation as none with the issue rated non-automatable, so real-world risk is largely confined to insiders or post-compromise tampering rather than scalable remote attacks.
Information disclosure in the Windows Event Log service allows an authenticated local attacker to read potentially sensitive memory contents. Affecting a broad range of Windows 10, 11, and Server editions, this low-severity flaw requires prior local access and only results in confidentiality impact, with no code execution or privilege escalation. No public exploit identified at time of analysis, and Microsoft has released patches.
An out-of-bounds read in the Microsoft Windows Storage Port Driver (CWE-125) lets an attacker who already has physical access to a device read past the end of a buffer and disclose kernel memory contents to an unauthorized party. Every supported Windows client and server build from Windows 10 1607 and Windows Server 2012 through Windows 11 26H2 and Windows Server 2025 is affected, as tracked in EUVD-2026-100340, and because the vector is AV:P the flaw cannot be reached remotely - it is confined to lost, stolen, or unattended hardware and evil-maid style scenarios. Microsoft has released a vendor patch, there is no public exploit identified at time of analysis, and CISA's SSVC decision framework rates exploitation as none and the issue as non-automatable, making this a genuinely low-priority item despite the CVSS confidentiality rating of High.
Improper authorization in the Windows Encrypting File System (EFS) lets an already-logged-in local user tamper with protected data that they should not be permitted to modify, yielding a high integrity impact with no confidentiality or availability impact (CVSS 5.5, AV:L/PR:L/UI:N, C:N/I:H/A:N). Only Windows 10, Windows 11, and Windows Server hosts that have not yet applied the current cumulative updates are exposed; the attack is strictly local, requires an interactive session and at least low-level privileges, and there is no public exploit identified at time of analysis (no CISA KEV entry, SSVC exploitation: none, EPSS not notable). This is a genuinely moderate, low-urgency issue rather than a high-priority emergency: vendor patches already exist for every affected build, so exposure is limited to unpatched systems where a low-privileged local user could subvert EFS authorization checks.
An out-of-bounds read (CWE-125) in Microsoft Digest Authentication on unpatched Windows client and server builds lets an authenticated local user disclose information from the host; the CVSS 3.1 vector (AV:L/PR:L/UI:N/S:U/C:H/I:N/A:N) confirms the attacker must already hold low-level privileges on the machine, needs no user interaction, and can only read data - with no impact on integrity or availability. Because reachability is local rather than remote, the component is the Windows Digest/SASL authentication provider itself, and exploitation is limited to memory disclosure on systems that have not yet installed the vendor fixes identified by EUVD build numbers. No public exploit code has been identified at time of analysis, there is no CISA KEV listing, and SSVC assesses the issue as not automatable with no observed exploitation, so it should be treated as a low-to-moderate-priority hardening item rather than an emergency.
An out-of-bounds read in the Windows Key Storage Provider (KSP) allows an authenticated, low-privileged local user to disclose memory contents from the calling process, as rated CVSS 3.1 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). Only systems running Windows builds below the fixed levels published in the Microsoft update guide and EUVD (for example, Windows 11 24H2 below 10.0.26100.9711 or Windows Server 2025 below 10.0.26100.33650) are affected; patched builds are not exploitable. The issue requires an existing local session and valid credentials, is not remotely reachable, and there is no public exploit identified at time of analysis; CISA's SSVC assessment rates exploitation as none and automatable as no, making this a moderate-severity, low-priority issue in practice.
