| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-09-07 | CVE-2021-28139 | Unspecified vulnerability in Espressif Esp-Idf The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly restrict the Feature Page upon reception of an LMP Feature Response Extended packet, allowing attackers in radio range to trigger arbitrary code execution in ESP32 via a crafted Extended Features bitfield payload. low complexity espressif | 8.8 |
| 2021-09-07 | CVE-2021-28135 | Unspecified vulnerability in Espressif Esp-Idf The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service (crash) in ESP32 by flooding the target device with LMP Feature Response data. low complexity espressif | 6.5 |
| 2021-09-07 | CVE-2021-28136 | Out-of-bounds Write vulnerability in Espressif Esp-Idf The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly handle the reception of multiple LMP IO Capability Request packets during the pairing process, allowing attackers in radio range to trigger memory corruption (and consequently a crash) in ESP32 via a replayed (duplicated) LMP packet. | 6.5 |
| 2020-08-31 | CVE-2020-13594 | Improper Input Validation vulnerability in Espressif Esp-Idf 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. | 6.5 |
| 2020-07-23 | CVE-2020-12638 | Cleartext Transmission of Sensitive Information vulnerability in Espressif Esp-Idf, Esp8266 Nonos SDK and Esp8266 Rtos SDK An encryption-bypass issue was discovered on Espressif ESP-IDF devices through 4.2, ESP8266_NONOS_SDK devices through 3.0.3, and ESP8266_RTOS_SDK devices through 3.3. | 6.8 |
