| An off-by-one error in the Zephyr project MQTT packet length decoder can result in memory corruption and possible remote code execution. NCC-ZEP-031 This issue affects: zephyrproject-rtos zephyr version 2.2.0 and later versions. |
| Improper handling of the full-buffer case in the Zephyr Bluetooth implementation can result in memory corruption. This issue affects: zephyrproject-rtos zephyr version 2.2.0 and later versions, and version 1.14.0 and later versions. |
| In updatehub_probe, right after JSON parsing is complete, objects\[1] is accessed from the output structure in two different places. If the JSON contained less than two elements, this access would reference unitialized stack memory. This could result in a crash, denial of service, or possibly an information leak. Provided the fix in CVE-2020-10059 is applied, the attack requires compromise of the server. See NCC-ZEP-030 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. version 2.2.0 and later versions. |
| The UpdateHub module disables DTLS peer checking, which allows for a man in the middle attack. This is mitigated by firmware images requiring valid signatures. However, there is no benefit to using DTLS without the peer checking. See NCC-ZEP-018 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. |
| Multiple syscalls in the Kscan subsystem perform insufficient argument validation, allowing code executing in userspace to potentially gain elevated privileges. See NCC-ZEP-006 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. |
| Multiple syscalls with insufficient argument validation See NCC-ZEP-006 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions. |
| An attacker who has obtained code execution within a user thread is able to elevate privileges to that of the kernel. See NCC-ZEP-001 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions. |
| The arm platform-specific code uses a signed integer comparison when validating system call numbers. An attacker who has obtained code execution within a user thread is able to elevate privileges to that of the kernel. See NCC-ZEP-001 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions. |
| The shell subsystem contains a buffer overflow, whereby an adversary with physical access to the device is able to cause a memory corruption, resulting in denial of service or possibly code execution within the Zephyr kernel. See NCC-NCC-019 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions. |
| A malformed JSON payload that is received from an UpdateHub server may trigger memory corruption in the Zephyr OS. This could result in a denial of service in the best case, or code execution in the worst case. See NCC-NCC-016 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. version 2.2.0 and later versions. |
| Out-of-bounds Write in the USB Mass Storage memoryWrite handler with unaligned Sizes See NCC-ZEP-024, NCC-ZEP-025, NCC-ZEP-026 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions. |
| USB DFU has a potential buffer overflow where the requested length (wLength) is not checked against the buffer size. This could be used by a malicious USB host to exploit the buffer overflow. See NCC-ZEP-002 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions. |
| zephyr-rtos version 1.12.0 contains a NULL base pointer reference vulnerability in sys_ring_buf_put(), sys_ring_buf_get() that can result in CPU Page Fault (error code 0x00000010). This attack appear to be exploitable via a malicious application call the vulnerable kernel APIs (system sys_ring_buf_get() and sys_ring_buf_put). |
| Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in the shell component of Zephyr allows a serial or telnet connected user to cause a crash, possibly with arbitrary code execution. This issue affects: Zephyr shell versions prior to 1.14.0 on all. |
| Use After Free vulnerability in the Zephyr shell allows a serial or telnet connected user to cause denial of service, and possibly remote code execution. This issue affects: Zephyr shell versions prior to 1.14.0 on all. |
| A buffer overflow has been found in the Zephyr Project's getaddrinfo() implementation in 1.9.0 and 1.10.0. |
| In ascs_cp_rsp_add in /subsys/bluetooth/audio/ascs.c, an unchecked tailroom could lead to a global buffer overflow. |
| No proper validation of the length of user input in olcp_ind_handler in zephyr/subsys/bluetooth/services/ots/ots_client.c. |
| In utf8_trunc in zephyr/lib/utils/utf8.c, last_byte_p can point to one byte before the string pointer if the string is empty. |
| BT: HCI: adv_ext_report Improper discarding in adv_ext_report |
