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.

dbcve analysis · moderate confidence

This is a NULL pointer dereference vulnerability in Zoom Workplace Apps for Windows. An authenticated user can trigger the vulnerability via network access, causing the application to crash and resulting in denial of service. The issue stems from the application attempting to dereference a NULL pointer without proper validation.

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 Settings > Apps > Installed Apps and look for Zoom-related applications such as Zoom Workplace Desktop, Zoom Rooms, Zoom Meeting SDK, or Zoom Rooms Controller. Alternatively, check Program Files for Zoom installation folders.
    Affected if Any Zoom product from the affected product list is installed
  2. Check Zoom Workplace Desktop version
    Open the Zoom desktop client, click your profile picture or initials in the top-right corner, then click 'Check for Updates' or look in Settings > About > Version. The version number will be displayed (e.g., 6.3.x).
    Affected if The installed version is below 6.4.0 (for example, 6.3.10, 6.2.14, etc.)
  3. Check Zoom Rooms version
    Open the Zoom Rooms application or access the Zoom Rooms controller interface. Navigate to Settings > Account Settings or About section to locate the version number.
    Affected if The installed version is below 6.4.0
  4. Check Zoom Workplace VDI version
    For virtual desktop installations, check the version through the VDI admin console or by right-clicking the Zoom icon, selecting 'About Zoom Workplace', and noting the version displayed.
    Affected if The version is below 6.1.17, OR between 6.1.18 and 6.2.12 inclusive, OR between 6.2.14 and 6.3.9 inclusive
  5. Confirm network meeting features are enabled
    Launch the Zoom application and verify that network-based meeting functionality is accessible. This includes checking if Join Meetings, Schedule Meetings, or instant meeting options are available to authenticated users.
    Affected if Authenticated users can join or host meetings over the network (this is the attack vector for the NULL pointer dereference)

You are affected if any Zoom product from the affected list is installed and its version falls below 6.4.0 (or falls within the specific VDI version ranges), and network meeting features are accessible to authenticated users.
