CVE-2025-46785
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 · uneditedBuffer over-read 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 confidenceA buffer over-read vulnerability in Zoom Workplace Apps for Windows allows an authenticated user to read beyond allocated memory boundaries when processing network data, causing the application to crash and result in denial of service.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Zoom productCheck Programs and Features or the application itself to determine which Zoom product is installed: Zoom Meeting SDK, Zoom Rooms, Zoom Rooms Controller, Zoom Workplace Desktop, or Zoom Workplace VDIAffected if Any of these Zoom products are installed
-
Determine installed version numberOpen the Zoom application, go to Help > About, or right-click the application icon and select Properties > Details to view the version numberAffected if Version number cannot be determined or is below 6.4.0 for most products, or falls within the VDI ranges (< 6.1.17, >= 6.1.18 and < 6.2.13, or >= 6.2.14 and < 6.3.10)
-
Verify network data processing is activeThe vulnerability triggers when processing network data during normal Zoom operation; no specific setting needs to be enabled as this is inherent to application functionalityAffected if The Zoom application is running and processing network communications with Zoom services
The user is affected if they have any Zoom product installed with a version below 6.4.0 (or the specific VDI version ranges) and the application is processing network data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.1.176.2.136.3.10
Apply vendor patches when released; until then, limit network access to Zoom services and implement network segmentation to reduce exposure to authenticated attackers.
6.4.0 or later for all affected products (Meeting SDK, Rooms, Rooms Controller, Workplace Desktop, Workplace VDI)
- 1. Identify the exact Zoom product and current version installed (Meeting SDK, Rooms, Rooms Controller, Workplace Desktop, or Workplace Virtual Desktop Infrastructure)
- 2. Navigate to the official Zoom download center at www.zoom.com or the Zoom support portal
- 3. Locate and download the fixed version: Meeting SDK, Rooms, Rooms Controller, and Workplace Desktop users should download version 6.4.0 or later; Workplace VDI users should download version 6.4.0 or later (this supersedes the earlier 6.1.17, 6.2.13, and 3.10 patch requirements)
- 4. Install the updated Zoom application with administrator privileges
- 5. Restart the Zoom application or reboot the system if required
- 6. Verify the installed version by checking Help > About Zoom in the application to confirm the fix is applied
