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.

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 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.
