| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-11-09 | CVE-2023-46894 | Inadequate Encryption Strength vulnerability in Espressif Esptool 4.6.2 An issue discovered in esptool 4.6.2 allows attackers to view sensitive information via weak cryptographic algorithm. | 7.5 |
| 2023-07-17 | CVE-2023-35818 | Unspecified vulnerability in Espressif products An issue was discovered on Espressif ESP32 3.0 (ESP32_rev300 ROM) devices. low complexity espressif | 6.8 |
| 2022-06-25 | CVE-2022-24893 | Out-of-bounds Write vulnerability in Espressif Esp-Idf ESP-IDF is the official development framework for Espressif SoCs. | 8.3 |
| 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 | 8.3 |
| 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 | 3.3 |
| 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. | 3.3 |
| 2021-07-14 | CVE-2021-34173 | Unspecified vulnerability in Espressif Esp32 Firmware An attacker can cause a Denial of Service and kernel panic in v4.2 and earlier versions of Espressif esp32 via a malformed beacon csa frame. | 7.8 |
| 2021-01-12 | CVE-2020-16146 | Classic Buffer Overflow vulnerability in Espressif Esp-Idf Espressif ESP-IDF 2.x, 3.0.x through 3.0.9, 3.1.x through 3.1.7, 3.2.x through 3.2.3, 3.3.x through 3.3.2, and 4.0.x through 4.0.1 has a Buffer Overflow in BluFi provisioning in btc_blufi_recv_handler function in blufi_prf.c. | 5.0 |
| 2020-08-31 | CVE-2020-13595 | Reachable Assertion vulnerability in Espressif Esp-Idf 4.0.0/4.1/4.2 The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion on the host stack when receiving a packet with an MIC failure. | 3.3 |
| 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. | 3.3 |
