CVE-2024-27246Network attack vector

Authenticated service interruption via use-after-free

Published Feb 25, 2025 · Updated Feb 25, 2025

Use-after-free in Zoom Workplace Apps before 5.17.11 allows remote authenticated users to interrupt service over a network. Zoom has not disclosed the affected component, the freed object's lifetime error, or the network input that triggers invalid memory access. A valid Zoom user session is required, and the documented consequence is limited to availability loss rather than data disclosure or modification.
