Exploitation Conditions

Exploitation requires that the target host has the Windows IP Over USB Service present and running (the service enabling IP connectivity to devices over USB, used by device/SDK tooling rather than a default always-on component), and that the attacker already holds authenticated low-privileged local access (AV:L/PR:L). No user interaction is needed (UI:N). Limiting factors: there is no remote vector, privilege escalation, or code execution - impact is confined to disclosure of memory contents (C:H/I:N/A:N), and hosts without the IP Over USB Service active are not exploitable.

Impact

This is a moderate-severity, low-priority issue rather than an urgent one. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, base 5.5) describes a locally-exploitable information disclosure requiring an already-authenticated low-privileged attacker on the host; it yields high confidentiality impact but no integrity or availability effect. CISA's SSVC decision framework reinforces the low urgency: Exploitation=none, Automatable=no, Technical Impact=partial. No EPSS score, KEV listing, or POC is present in the provided data, so there is no evidence of active exploitation or available exploit code. The signals are consistent with one another - a local, privilege-dependent memory-disclosure bug with no mass-exploitation vector. Note that no EPSS probability was supplied, so widespread-exploitation likelihood cannot be quantified from this input; absence of KEV/POC is not proof none exists, only that none is recorded here.

Exploit ScenarioDerived

An attacker who already has low-privileged local access to a Windows host running the IP Over USB Service triggers an out-of-bounds read (CWE-125) in that service to read memory beyond an intended buffer boundary, disclosing potentially sensitive in-memory data. Because the CVSS vector is AV:L/PR:L/UI:N with no scope change, this requires existing authenticated local foothold and no user interaction, but offers no code execution or privilege gain. No public exploit identified at time of analysis.

AnalysisAIv1 – Oct 14, 2026

An out-of-bounds read in the Windows IP Over USB Service (the component that exposes IP connectivity to devices over USB, typically used by device and SDK tooling rather than being a default always-on service) lets an attacker who already holds low-privileged local credentials read beyond intended memory boundaries and disclose information. According to the assessed CVSS 3.1 vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, this is a local, authenticated, no-user-interaction information disclosure with high confidentiality impact but no integrity or availability impact, and there is no remote vector, privilege escalation, or code execution. There is no public exploit identified at time of analysis and CISA's SSVC assessment rates exploitation as none with the issue not automatable; this is a moderate-severity, low-priority issue rather than an urgent one, and vendor patches are available.

RemediationAI

Vendor-released patches are available: apply the Microsoft updates that bring each affected build to or above the fixed levels - Windows 10 21H2/22H2 to 10.0.19044.7807, Windows 11 23H2 to 10.0.22631.7652, 24H2 to 10.0.26100.9711, 25H2 to 10.0.26200.9711, 26H1 to 10.0.28000.3231, and 26H2 to 10.0.26300.9711, plus Windows Server 2022 to 10.0.20348.5761 and Windows Server 2025 (including Server Core) to 10.0.26100.33650, following the guidance at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-70011. There is no widespread exploitation pressure (SSVC exploitation: none, no public exploit identified), so patching can follow normal monthly cycles for most environments, prioritizing hosts that run the IP Over USB Service for device or SDK workflows. As a compensating control on systems where the update cannot be applied promptly, stop and disable the Windows IP Over USB Service (and avoid connecting untrusted USB devices), which removes the vulnerable code path but will break USB-based IP connectivity for device/SDK tooling; additionally, restrict local interactive logon and code execution to trusted users, since exploitation still requires an authenticated low-privileged local foothold and cannot be triggered remotely. Monitor for unexpected local privilege use or process access patterns against the service in the interim.

Technical ContextAI · show details

The vulnerability is classified as CWE-125 (Out-of-bounds Read) in the Windows IP Over USB Service, a Windows component that provides IP-based communication to devices attached over USB so that device/SDK tooling can talk to them across a network-style interface instead of raw USB transfers. The root cause class is improper bounds validation on a memory buffer read: the service reads beyond the end (or outside the intended range) of a buffer while processing input, returning adjacent memory contents to the caller. Because privilege requirements are low but not none (PR:L in the assessed vector), the attacker must already be able to execute code locally as a low-privileged user on a host where the service is present and running; the CVSS scope is unchanged (S:U) and the impact is limited to confidentiality (C:H) with no integrity or availability effects. Exploitation cannot be triggered remotely, requires no user interaction (UI:N), and is not considered automatable per CISA SSVC, which limits its practical value as part of a broad attack campaign. From the EUVD data the service ships across the current Windows client and server line, including Windows 10 21H2/22H2, Windows 11 23H2 through 26H2, Windows Server 2022, and Windows Server 2025 (including Server Core).

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
