CVE-2025-46785Network attack vector

Authenticated service interruption via buffer over-read

Published May 14, 2025 · Updated May 14, 2025

Buffer over-read in Zoom Workplace Apps for Windows allows remote authenticated users to interrupt affected clients over a network. Zoom has not disclosed the affected code locus or the operation that reads beyond the intended buffer boundary. Network access with a valid account is required, and the resulting denial of service is bounded to availability because the exact interruption mode is undisclosed.
