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
NULL pointer dereference in some Zoom Workplace Apps for Windows 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.

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
    Open Windows Programs and Features (appwiz.cpl) or check the Zoom application installed: Zoom Workplace Desktop, Zoom Rooms, Zoom Rooms Controller, or look for Zoom Meeting SDK in applications that use it. For VDI, check the virtual desktop client configuration.
    Affected if Any Zoom product from the list is installed (Meeting SDK, Rooms, Rooms Controller, Workplace Desktop, or Workplace VDI)
  2. Determine Zoom Workplace Desktop version
    Open Zoom Workplace Desktop app, click your profile picture or the gear icon, then select 'About Zoom' or 'Check for Updates' to view the exact version number (e.g., 6.x.x).
    Affected if Version is less than 6.4.0 (e.g., 6.3.10 or earlier)
  3. Determine Zoom Rooms version
    Open the Zoom Rooms application, go to Settings or the room control interface, and locate the version information typically shown in the About or System Information section.
    Affected if Version is less than 6.4.0
  4. Determine Zoom Rooms Controller version
    Open the Zoom Rooms Controller app on the designated controller device (tablet or touch panel), access the About or Settings menu to view the installed version.
    Affected if Version is less than 6.4.0
  5. Determine Zoom Workplace VDI version
    Check the VDI client configuration or session information provided by your virtual infrastructure (VMware Horizon, Citrix, etc.) for the Zoom VDI component version, or contact your VDI administrator for the installed Zoom version.
    Affected if Version is less than 6.1.17, OR between 6.1.18 and 6.2.12 inclusive, OR between 6.2.14 and 6.3.9 inclusive

Your environment is affected if any installed Zoom product (Desktop, Rooms, Rooms Controller, Meeting SDK, or VDI) is running a version lower than 6.4.0, or if VDI falls into the specific vulnerable version ranges.

Interim mitigation

Apply the Zoom vendor patch or update to the latest version of Zoom Workplace Apps for Windows. Organizations should verify all deployed instances are running the patched version.

Recommended fix High confidence

Zoom Workplace Apps version 6.4.0 or later (VDI: 6.1.17+, 6.2.13+, or 6.3.10+)

  1. 1. Identify which Zoom product(s) are in use (Meeting SDK, Rooms, Rooms Controller, Workplace Desktop, or Workplace VDI)
  2. 2. Check the current installed version of the affected Zoom application
  3. 3. Download the fixed version from the official Zoom website (www.zoom.com) or your Zoom account portal
  4. 4. For Meeting SDK, Rooms, Rooms Controller, and Workplace Desktop: Upgrade to version 6.4.0 or later
  5. 5. For Workplace VDI: Upgrade to version 6.1.17 or later for the 6.1.x branch; 6.2.13 or later for the 6.2.x branch; 6.3.10 or later for the 6.3.x branch (or preferably the latest stable release)
  6. 6. Verify the upgrade was successful by checking the version number in the application
