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
Buffer overflow in some Zoom Workplace Apps, SDKs, Rooms Clients, and Rooms Controllers may allow an authenticated user to conduct a denial of service via network access.

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 · moderate confidence

A buffer overflow vulnerability in Zoom Workplace Apps, SDKs, Rooms Clients, and Rooms Controllers allows an authenticated user with network access to trigger the overflow, potentially causing a denial of service condition.

MitigationApply vendor-supplied patches or update all affected Zoom products to the latest fixed versions. Prioritize systems with direct network exposure.

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. Identify installed Zoom product
    Check Programs and Features (Windows) or Applications folder (Mac) for Zoom Workplace, Zoom Rooms, Zoom Meeting SDK, or Zoom Rooms Controller. Look for the Zoom executable in the installation directory and note the product name.
    Affected if Any Zoom product from the affected list is installed (Workplace Desktop, Meeting SDK, Rooms, Rooms Controller, Workplace, or Workplace VDI)
  2. Find installed Zoom version
    For desktop apps: Open Zoom client, click Help > About Zoom to display the version number. For Rooms: Access Zoom Rooms controller or web portal, navigate to Account Management or Room Settings to view version. For SDK: Check the SDK version in project references or documentation.
    Affected if A version number is displayed that can be compared to the affected ranges
  3. Compare version to affected ranges
    Match your installed version number against the following vulnerable ranges: Workplace Desktop, Meeting SDK, Rooms, Rooms Controller, Workplace: versions below 6.1.0 are vulnerable. Workplace VDI: versions below 5.17.14 OR versions 6.0.0 through 6.0.10 are vulnerable.
    Affected if Installed version is below 6.1.0 (for non-VDI products) OR below 5.17.14 OR between 6.0.0 and 6.0.10 (for VDI)
  4. Confirm network exposure
    Verify if the Zoom client or service has network connectivity enabled. Check if the system can connect to zoom.us or if local network ports used by Zoom (typically 80/443, 8801/8802 for video) are accessible.
    Affected if Network access to Zoom services is enabled, as the attacker requires network access to trigger the overflow

You are affected if any Zoom product from the affected list is installed with a version below 6.1.0 (or the specific VDI ranges) and the system has network exposure.

Interim mitigation

Apply vendor-supplied patches or update all affected Zoom products to the latest fixed versions. Prioritize systems with direct network exposure.

Recommended fix High confidence

6.1.0 (or later) for Workplace Desktop/SDK/Rooms/Room Controller/Workspace; 6.0.11 or 5.17.14 for Workplace VDI

  1. 1. Identify the affected Zoom product and current version installed (Help > About in desktop apps)
  2. 2. For Workplace Desktop, Meeting SDK, Rooms, Rooms Controller, and Workplace: Upgrade to version 6.1.0 or later
  3. 3. For Workplace Virtual Desktop Infrastructure: If running 6.0.x, upgrade to 6.0.11 or later; if running 5.x, upgrade to 5.17.14 or later
  4. 4. Download the updated version from the official Zoom download center (zoom.us/download)
  5. 5. Run the installer and follow prompts to complete the upgrade
  6. 6. Verify the new version is installed after upgrade completes
  7. 7. Test that Zoom services start properly and functionality is intact
