Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Exposure of sensitive information to an unauthorized actor in Windows Remote Procedure Call allows an authorized attacker to disclose information locally.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a local information disclosure vulnerability in Windows Remote Procedure Call (RPC). An authorized attacker with local access can exploit Windows RPC to disclose sensitive information that they should not have access to. The vulnerability requires the attacker to have some form of valid credentials or authorization on the target system, but does not require administrator privileges.

MitigationApply the Microsoft security update for CVE-2026-32085 via Windows Update or your organization's patch management process. Verify that RPC services are running with least-privilege service accounts and follow principle of least privilege for user accounts.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Windows build version
    Open Command Prompt or PowerShell and run 'winver' or 'systeminfo | findstr /B /C:"OS Version"' to see the full build number
    Affected if The build number is lower than any of these: 14393.9060 (Win10 1607), 17763.8644 (Win10 1809), 19044.7184 (Win10 21h2/22h2), 22631.6936 (Win11 23h2), 26100.8246 (Win11 24h2/25h2), or 28000.1836 (Win11 26h1)
  2. Verify RPC service status
    Open Services console (services.msc) or run 'sc query rpcss' in Command Prompt to check if the Remote Procedure Call (RPC) service is running
    Affected if The RPC service is running (this is the default state; the vulnerability applies when RPC is active)
  3. Confirm security update is absent
    Run 'wmic qfe list' or check Windows Update history in Settings > Windows Update > Update history for a security update corresponding to CVE-2026-32085
    Affected if No security update for CVE-2026-32085 is listed in the installed updates

You are affected if your Windows build version is lower than the fixed builds listed AND the RPC service is running AND the CVE-2026-32085 security update is not installed.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
