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 exists in Zoom Workplace Apps, SDKs, Rooms Clients, and Rooms Controllers. An authenticated user can exploit this flaw via network access to cause a denial of service condition. The vulnerability stems from insufficient bounds checking when processing certain network inputs, allowing a user to overflow a memory buffer and crash the application or trigger unexpected behavior.

MitigationApply vendor-supplied patches or update to the latest version of Zoom products as specified in Zoom's security advisories. Review and enforce authentication controls to limit exposure to authenticated users only.

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 installed programs for Zoom Workplace Desktop, Zoom Rooms, Zoom Rooms Controller, Zoom Meeting SDK, or Zoom Workplace VDI. On Windows, check Add/Remove Programs or the Zoom application folder. On macOS, check /Applications folder.
    Affected if Any of the listed Zoom products are installed
  2. Determine installed version number
    Open the Zoom application, go to Help > About Zoom (desktop/client) or check the application properties. For SDK versions, check the SDK documentation or version manifest. For Rooms, check the controller or room settings.
    Affected if Version cannot be determined or is below 6.1.0 for most products, or below 5.17.14 / between 6.0.0 and 6.0.10 for VDI
  3. Compare version against affected ranges
    If product is Zoom Workplace Desktop, Meeting SDK, Rooms, Rooms Controller, or Zoom Workplace (non-VDI): verify version is 6.1.0 or higher. If product is Zoom Workplace VDI: verify version is 5.17.14 or higher OR 6.0.11 or higher.
    Affected if Version is below 6.1.0 (non-VDI products) OR below 5.17.14 OR between 6.0.0 and 6.0.10 (VDI)
  4. Assess network exposure
    Verify if the Zoom client has network connectivity enabled and is configured to connect to Zoom servers or corporate meeting infrastructure. Check firewall rules and network configuration.
    Affected if Client has active network access and can receive remote network inputs

Environment is affected if any Zoom product from the list is installed with a version below the fixed releases (6.1.0 for most products, 5.17.14 or 6.0.11+ for VDI) and has network connectivity.
