| CVE-2025-27840 | 1 Espressif | 2 Esp32, Esp32 Firmware | 2025-05-12 | 6.8 Medium |
| Espressif ESP32 chips allow 29 hidden HCI commands, such as 0xFC02 (Write memory). | ||||
| CVE-2023-35818 | 1 Espressif | 44 Esp-eye, Esp-eye Firmware, Esp32-d0wd-v3 and 41 more | 2024-11-21 | 6.8 Medium |
| An issue was discovered on Espressif ESP32 3.0 (ESP32_rev300 ROM) devices. An EMFI attack on ECO3 provides the attacker with a capability to influence the PC value at the CPU context level, regardless of Secure Boot and Flash Encryption status. By using this capability, the attacker can exploit another behavior in the chip to gain unauthorized access to the ROM download mode. Access to ROM download mode may be further exploited to read the encrypted flash content in cleartext format or execute stub code. | ||||
| CVE-2021-41104 | 2 Esphome, Espressif | 3 Esphome Firmware, Esp32, Esp8266 | 2024-11-21 | 7.5 High |
| ESPHome is a system to control the ESP8266/ESP32. Anyone with web_server enabled and HTTP basic auth configured on version 2021.9.1 or older is vulnerable to an issue in which `web_server` allows over-the-air (OTA) updates without checking user defined basic auth username & password. This issue is patched in version 2021.9.2. As a workaround, one may disable or remove `web_server`. | ||||
| CVE-2021-34173 | 1 Espressif | 2 Esp32, Esp32 Firmware | 2024-11-21 | 7.5 High |
| 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. The device requires a reboot to recover. | ||||
| CVE-2021-28139 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 8.8 High |
| 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. | ||||
| CVE-2021-28136 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 6.5 Medium |
| 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. | ||||
| CVE-2020-13595 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 6.5 Medium |
| 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. An attacker within radio range can silently trigger the assertion (which disables the target's BLE stack) by sending a crafted sequence of BLE packets. | ||||
| CVE-2020-13594 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 6.5 Medium |
| 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. | ||||
| CVE-2019-17391 | 1 Espressif | 8 Esp32-d0wd, Esp32-d0wd Firmware, Esp32-d2wd and 5 more | 2024-11-21 | 4.6 Medium |
| An issue was discovered in the Espressif ESP32 mask ROM code 2016-06-08 0 through 2. Lack of anti-glitch mitigations in the first stage bootloader of the ESP32 chip allows an attacker (with physical access to the device) to read the contents of read-protected eFuses, such as flash encryption and secure boot keys, by injecting a glitch into the power supply of the chip shortly after reset. | ||||
