CVE-2025-1675 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 8.2 HIGH
The function dns_copy_qname in dns_pack.c performs performs a memcpy operation with an untrusted field and does not check if the source buffer is large enough to contain the copied data.
CVE-2025-1674 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 8.2 HIGH
A lack of input validation allows for out of bounds reads caused by malicious or malformed packets.
CVE-2025-1673 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 8.2 HIGH
A malicious or malformed DNS packet without a payload can cause an out-of-bounds read, resulting in a crash (denial of service) or an incorrect computation.
CVE-2025-10458 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.6 HIGH
Parameters are not validated or sanitized, and are later used in various internal operations.
CVE-2025-10457 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 4.3 MEDIUM
The function responsible for handling BLE connection responses does not verify whether a response is expected—that is, whether the device has initiated a connection request. Instead, it relies solely on identifier matching.
CVE-2025-10456 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.1 HIGH
A vulnerability was identified in the handling of Bluetooth Low Energy (BLE) fixed channels (such as SMP or ATT). Specifically, an attacker could exploit a flaw that causes the BLE target (i.e., the device under attack) to attempt to disconnect a fixed channel, which is not allowed per the Bluetooth specification. This leads to undefined behavior, including potential assertion failures, crashes, or memory corruption, depending on the BLE stack implementation.
CVE-2024-8798 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.5 HIGH
No proper validation of the length of user input in olcp_ind_handler in zephyr/subsys/bluetooth/services/ots/ots_client.c.
CVE-2024-6444 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 6.3 MEDIUM
No proper validation of the length of user input in olcp_ind_handler in zephyr/subsys/bluetooth/services/ots/ots_client.c.
CVE-2024-6443 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 6.3 MEDIUM
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.
CVE-2024-6442 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 6.3 MEDIUM
In ascs_cp_rsp_add in /subsys/bluetooth/audio/ascs.c, an unchecked tailroom could lead to a global buffer overflow.
CVE-2024-6259 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.6 HIGH
BT: HCI: adv_ext_report Improper discarding in adv_ext_report
CVE-2024-6258 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 6.8 MEDIUM
BT: Missing length checks of net_buf in rfcomm_handle_data
CVE-2024-6137 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.6 HIGH
BT: Classic: SDP OOB access in get_att_search_list
CVE-2024-6135 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.6 HIGH
BT:Classic: Multiple missing buf length checks
CVE-2024-5931 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 6.3 MEDIUM
BT: Unchecked user input in bap_broadcast_assistant
CVE-2024-5754 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 8.2 HIGH
BT: Encryption procedure host vulnerability
CVE-2024-4785 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 7.6 HIGH
BT: Missing Check in LL_CONNECTION_UPDATE_IND Packet Leads to Division by Zero
CVE-2024-3332 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 6.5 MEDIUM
A malicious BLE device can send a specific order of packet sequence to cause a DoS attack on the victim BLE device
CVE-2024-3077 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 6.8 MEDIUM
An malicious BLE device can crash BLE victim device by sending malformed gatt packet
CVE-2024-1638 1 Zephyrproject 1 Zephyr 2026-06-17 N/A 8.2 HIGH
The documentation specifies that the BT_GATT_PERM_READ_LESC and BT_GATT_PERM_WRITE_LESC defines for a Bluetooth characteristic: Attribute read/write permission with LE Secure Connection encryption. If set, requires that LE Secure Connections is used for read/write access, however this is only true when it is combined with other permissions, namely BT_GATT_PERM_READ_ENCRYPT/BT_GATT_PERM_READ_AUTHEN (for read) or BT_GATT_PERM_WRITE_ENCRYPT/BT_GATT_PERM_WRITE_AUTHEN (for write), if these additional permissions are not set (even in secure connections only mode) then the stack does not perform any permission checks on these characteristics and they can be freely written/read.
