| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-07-10 | CVE-2023-1901 | Out-of-bounds Write vulnerability in Zephyrproject Zephyr The bluetooth HCI host layer logic not clearing a global reference to a semaphore after synchronously sending HCI commands may allow a malicious HCI Controller to cause the use of a dangling reference in the host layer, leading to a crash (DoS) or potential RCE on the Host layer. | 8.0 |
| 2023-07-10 | CVE-2023-1902 | Use After Free vulnerability in Zephyrproject Zephyr The bluetooth HCI host layer logic not clearing a global reference to a state pointer after handling connection events may allow a malicious HCI Controller to cause the use of a dangling reference in the host layer, leading to a crash (DoS) or potential RCE on the Host layer. | 8.0 |
| 2023-07-10 | CVE-2023-2234 | Type Confusion vulnerability in Zephyrproject Zephyr Union variant confusion allows any malicious BT controller to execute arbitrary code on the Zephyr host. | 8.8 |
| 2023-05-30 | CVE-2023-0779 | NULL Pointer Dereference vulnerability in Zephyrproject Zephyr At the most basic level, an invalid pointer can be input that crashes the device, but with more knowledge of the device’s memory layout, further exploitation is possible. | 7.7 |
| 2023-02-26 | CVE-2021-3329 | Improper Initialization vulnerability in Zephyrproject Zephyr 2.4.0 Lack of proper validation in HCI Host stack initialization can cause a crash of the bluetooth stack | 6.5 |
| 2023-01-25 | CVE-2023-0396 | Out-of-bounds Read vulnerability in Zephyrproject Zephyr A malicious / defective bluetooth controller can cause buffer overreads in the most functions that process HCI command responses. | 6.8 |
| 2023-01-25 | CVE-2022-3806 | Double Free vulnerability in Zephyrproject Zephyr Inconsistent handling of error cases in bluetooth hci may lead to a double free condition of a network buffer. | 9.8 |
| 2023-01-19 | CVE-2023-0397 | Improper Initialization vulnerability in Zephyrproject Zephyr A malicious / defect bluetooth controller can cause a Denial of Service due to unchecked input in le_read_buffer_size_complete. | 6.5 |
| 2023-01-11 | CVE-2021-3966 | Classic Buffer Overflow vulnerability in Zephyrproject Zephyr usb device bluetooth class includes a buffer overflow related to implementation of net_buf_add_mem. | 8.8 |
| 2023-01-11 | CVE-2022-0553 | Cleartext Transmission of Sensitive Information vulnerability in Zephyrproject Zephyr There is no check to see if slot 0 is being uploaded from the device to the host. | 4.6 |
