CVE-2024-24692

Local service interruption via installer race

Published Mar 13, 2024 · Updated Aug 1, 2024

TOCTOU race in the Zoom Rooms Client for Windows installer before 5.17.5 allows local users to interrupt service during installation. Zoom identifies the installer and race class but has not disclosed the checked resource, competing operation, or timing window that creates the unsafe state. Exploitation requires low-privileged local access, high-complexity timing, and user interaction, and the documented impact is limited to availability.
