CVE-2024-51428Network attack vector

Service interruption via crafted data-channel packet

Published Nov 7, 2024 · Updated Nov 8, 2024

Denial of service in ESP-IDF 5.3.0 allows remote attackers to interrupt an ESP32 application via a crafted data-channel packet. Public records identify data-channel packet handling as the locus but do not disclose which parser or allocation lacks an effective limit. No authentication or user interaction is required, and the documented consequence is availability loss without data disclosure or modification.
