| In the Linux kernel, the following vulnerability has been resolved:
Revert "Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work"
This reverts commit 1e9ac114c4428fdb7ff4635b45d4f46017e8916f.
This patch introduces a possible null-ptr-def problem. Revert it. And the
fixed bug by this patch have resolved by commit 73f7b171b7c0 ("Bluetooth:
btsdio: fix use after free bug in btsdio_remove due to race condition"). |
| AuntyFey Smart Combination Lock firmware versions as of 2025-12-24 contain a vulnerability that allows an unauthenticated attacker within Bluetooth Low Energy (BLE) range to cause a denial of service by repeatedly initiating BLE connections. Sustained connection attempts interrupt keypad authentication input and repeatedly force the device into lockout states, preventing legitimate users from unlocking the device. |
| Some Sciener-based locks support plaintext message processing over Bluetooth Low Energy, allowing unencrypted malicious commands to be passed to the lock. These malicious commands, less then 16 bytes in length, will be processed by the lock as if they were encrypted communications. This can be further exploited by an attacker to compromise the lock's integrity. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: return ERR_PTR instead of NULL when there is no link
hci_connect_sco currently returns NULL when there is no link (i.e. when
hci_conn_link() returns NULL).
sco_connect() expects an ERR_PTR in case of any error (see line 266 in
sco.c). Thus, hcon set as NULL passes through to sco_conn_add(), which
tries to get hcon->hdev, resulting in dereferencing a NULL pointer as
reported by syzkaller.
The same issue exists for iso_connect_cis() calling hci_connect_cis().
Thus, make hci_connect_sco() and hci_connect_cis() return ERR_PTR
instead of NULL. |
| Improper conditions check for some Intel(R) Wireless Bluetooth(R) products for Windows before version 23.20 may allow a privileged user to potentially enable denial of service via local access. |
| QLowEnergyController in Qt before 6.8.2 mishandles malformed Bluetooth ATT commands, leading to an out-of-bounds read (or division by zero). This is fixed in 5.15.19, 6.5.9, and 6.8.2. |
| Insecure permissions in the Bluetooth Low Energy (BLE) component of Fire-Boltt Artillery Smart Watch NJ-R6E-10.3 allow attackers to cause a Denial of Service (DoS). |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: mediatek: Fix kernel crash when releasing mtk iso interface
When performing reset tests and encountering abnormal card drop issues
that lead to a kernel crash, it is necessary to perform a null check
before releasing resources to avoid attempting to release a null pointer.

| WHILL Model C2 Electric Wheelchairs and Model F Power Chairs do not enforce authentication for Bluetooth connections. An attacker within range can pair with the device and issue movement commands, override speed restrictions, and manipulate configuration profiles without any credentials or user interaction. |
| In the Airoha Bluetooth audio SDK, there is a possible permission bypass that allows access critical data of RACE protocol through Bluetooth LE GATT service. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| A state machine transition flaw in the Bluetooth Low Energy (BLE) stack of Cypress PSoC4 v3.66 allows attackers to bypass the pairing process and authentication via a crafted pairing_failed packet. |
| An issue was discovered in the COROS application through 3.8.12 for Android. Bluetooth pairing and bonding is neither initiated nor enforced by the application itself. Also, the watch does not enforce pairing and bonding. As a result, any data transmitted via BLE remains unencrypted, allowing attackers within Bluetooth range to eavesdrop on the communication. Furthermore, even if a user manually initiates pairing and bonding in the Android settings, the application continues to transmit data without requiring the watch to be bonded. This fallback behavior enables attackers to exploit the communication, for example, by conducting an active machine-in-the-middle attack. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl8xxxu: Fix memory leaks with RTL8723BU, RTL8192EU
The wifi + bluetooth combo chip RTL8723BU can leak memory (especially?)
when it's connected to a bluetooth audio device. The busy bluetooth
traffic generates lots of C2H (card to host) messages, which are not
freed correctly.
To fix this, move the dev_kfree_skb() call in rtl8xxxu_c2hcmd_callback()
inside the loop where skb_dequeue() is called.
The RTL8192EU leaks memory because the C2H messages are added to the
queue and left there forever. (This was fine in the past because it
probably wasn't sending any C2H messages until commit e542e66b7c2e
("wifi: rtl8xxxu: gen2: Turn on the rate control"). Since that commit
it sends a C2H message when the TX rate changes.)
To fix this, delete the check for rf_paths > 1 and the goto. Let the
function process the C2H messages from RTL8192EU like the ones from
the other chips.
Theoretically the RTL8188FU could also leak like RTL8723BU, but it
most likely doesn't send C2H messages frequently enough.
This change was tested with RTL8723BU by Erhard F. I tested it with
RTL8188FU and RTL8192EU. |
| An integer overflow condition exists in Bluetooth Host stack, within the bt_br_acl_recv routine a critical path for processing inbound BR/EDR L2CAP traffic. |
|
An implicit intent vulnerability was reported in the Motorola Ready For application that could allow a local attacker to read information about connected Bluetooth audio devices.
|
| The specific flaw exists within the Bluetooth stack developed by Alps Alpine of the Infotainment ECU manufactured by Bosch. The issue results from the lack of proper boundary validation of user-supplied data, which can result in a stack-based buffer overflow when receiving a specific packet on the established upper layer L2CAP channel. An attacker can leverage this vulnerability to obtain remote code execution on the Infotainment ECU with root privileges.
First identified on Nissan Leaf ZE1 manufactured in 2020. |
| An issue in the Bluetooth Low Energy implementation of Realtek RTL8762E BLE SDK v1.4.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted ll_terminate_ind packet. |
| An issue was discovered in Lush 2 through 2020-02-25. Due to the lack of Bluetooth traffic encryption, it is possible to hijack an ongoing Bluetooth connection between the Lush 2 and a mobile phone. This allows an attacker to gain full control over the device. |
| A specific flaw exists within the Bluetooth stack of the MIB3 infotainment system. The issue results from the disabled abortion flag eventually leading to bypassing assertion functions.
The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources. |
