VAR-202008-0041

Vulnerability from variot - Updated: 2025-01-30 20:04

The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.2 and earlier (for ESP32 devices) does not properly restrict the channel map field of the connection request packet on reception, allowing attackers in radio range to cause a denial of service (crash) via a crafted packet. ESP-IDF Is vulnerable to input validation.Denial of service (DoS) It may be put into a state. Espressif ESP-IDF is a development framework for the Internet of Things of China Espressif. Espressif ESP-IDF 4.2 and earlier versions have security vulnerabilities. Attackers use specially crafted data packets to cause denial of service
