| CVE-2025-65821 | 1 Espressif | 1 Esp32 | 2025-12-12 | 7.5 High |
| As UART download mode is still enabled on the ESP32 chip on which the firmware runs, an adversary can dump the flash from the device and retrieve sensitive information such as details about the current and previous Wi-Fi network from the NVS partition. Additionally, this allows the adversary to reflash the device with their own firmware which may contain malicious modifications. | ||||
| CVE-2025-65829 | 1 Espressif | 1 Esp32 | 2025-12-12 | 6.8 Medium |
| The ESP32 system on a chip (SoC) that powers the Meatmeet basestation device was found to lack Secure Boot. The Secure Boot feature ensures that only authenticated software can execute on the device. The Secure Boot process forms a chain of trust by verifying all mutable software entities involved in the Application Startup Flow. As a result, an attacker with physical access to the device can flash modified firmware to the device, resulting in the execution of malicious code upon startup. | ||||
| CVE-2025-65822 | 1 Espressif | 1 Esp32 | 2025-12-12 | 6.8 Medium |
| The ESP32 system on a chip (SoC) that powers the Meatmeet Pro was found to have JTAG enabled. By leaving JTAG enabled on an ESP32 in a commercial product an attacker with physical access to the device can connect over this port and reflash the device's firmware with malicious code which will be executed upon running. As a result, the victim will lose access to the functionality of their device and the attack may gain unauthorized access to the victim's Wi-Fi network by re-connecting to the SSID defined in the NVS partition of the device. | ||||
| CVE-2025-65092 | 1 Espressif | 2 Esp-idf, Esp32 | 2025-11-25 | N/A |
| ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.1, 5.4.3, and 5.3.4, when the ESP32-P4 uses its hardware JPEG decoder, the software parser lacks necessary validation checks. A specially crafted (malicious) JPEG image could exploit the parsing routine and trigger an out-of-bounds array access. This issue has been fixed in versions 5.5.2, 5.4.4, and 5.3.5. At time of publication versions 5.5.2, 5.4.4, and 5.3.5 have not been released but are fixed respectively in commits 4b8f585, c79cb4d, and 34e2726. | ||||
| 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-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. | ||||
