| CVE-2016-9804 | 1 Bluez | 1 Bluez | 2025-04-12 | N/A |
| In BlueZ 5.42, a buffer overflow was observed in "commands_dump" function in "tools/parser/csr.c" source file. The issue exists because "commands" array is overflowed by supplied parameter due to lack of boundary checks on size of the buffer from frame "frm->ptr" parameter. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash. | ||||
| CVE-2016-9803 | 1 Bluez | 1 Bluez | 2025-04-12 | N/A |
| In BlueZ 5.42, an out-of-bounds read was observed in "le_meta_ev_dump" function in "tools/parser/hci.c" source file. This issue exists because 'subevent' (which is used to read correct element from 'ev_le_meta_str' array) is overflowed. | ||||
| CVE-2024-8805 | 1 Bluez | 1 Bluez | 2024-12-20 | 8.8 High |
| BlueZ HID over GATT Profile Improper Access Control Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the HID over GATT Profile. The issue results from the lack of authorization prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-25177. | ||||
| CVE-2022-39177 | 3 Bluez, Canonical, Debian | 3 Bluez, Ubuntu Linux, Debian Linux | 2024-11-21 | 8.8 High |
| BlueZ before 5.59 allows physically proximate attackers to cause a denial of service because malformed and invalid capabilities can be processed in profiles/audio/avdtp.c. | ||||
| CVE-2022-39176 | 3 Bluez, Canonical, Debian | 3 Bluez, Ubuntu Linux, Debian Linux | 2024-11-21 | 8.8 High |
| BlueZ before 5.59 allows physically proximate attackers to obtain sensitive information because profiles/audio/avrcp.c does not validate params_len. | ||||
| CVE-2022-0204 | 3 Bluez, Debian, Fedoraproject | 3 Bluez, Debian Linux, Fedora | 2024-11-21 | 8.8 High |
| A heap overflow vulnerability was found in bluez in versions prior to 5.63. An attacker with local network access could pass specially crafted files causing an application to halt or crash, leading to a denial of service. | ||||
| CVE-2021-43400 | 2 Bluez, Debian | 2 Bluez, Debian Linux | 2024-11-21 | 9.1 Critical |
| An issue was discovered in gatt-database.c in BlueZ 5.61. A use-after-free can occur when a client disconnects during D-Bus processing of a WriteValue call. | ||||
| CVE-2021-41229 | 3 Bluez, Debian, Redhat | 3 Bluez, Debian Linux, Enterprise Linux | 2024-11-21 | 4.3 Medium |
| BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash. | ||||
| CVE-2021-3658 | 2 Bluez, Fedoraproject | 2 Bluez, Fedora | 2024-11-21 | 6.5 Medium |
| bluetoothd from bluez incorrectly saves adapters' Discoverable status when a device is powered down, and restores it when powered up. If a device is powered down while discoverable, it will be discoverable when powered on again. This could lead to inadvertent exposure of the bluetooth stack to physically nearby attackers. | ||||
| CVE-2021-3588 | 1 Bluez | 1 Bluez | 2024-11-21 | 3.3 Low |
| The cli_feat_read_cb() function in src/gatt-database.c does not perform bounds checks on the 'offset' variable before using it as an index into an array for reading. | ||||
| CVE-2021-0129 | 4 Bluez, Debian, Linux and 1 more | 4 Bluez, Debian Linux, Linux Kernel and 1 more | 2024-11-21 | 5.7 Medium |
| Improper access control in BlueZ may allow an authenticated user to potentially enable information disclosure via adjacent access. | ||||
| CVE-2020-27153 | 4 Bluez, Debian, Opensuse and 1 more | 4 Bluez, Debian Linux, Leap and 1 more | 2024-11-21 | 8.6 High |
| In BlueZ before 5.55, a double free was found in the gatttool disconnect_cb() routine from shared/att.c. A remote attacker could potentially cause a denial of service or code execution, during service discovery, due to a redundant disconnect MGMT event. | ||||
| CVE-2020-24490 | 3 Bluez, Linux, Redhat | 3 Bluez, Linux Kernel, Enterprise Linux | 2024-11-21 | 6.5 Medium |
| Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of service via adjacent access. This affects all Linux kernel versions that support BlueZ. | ||||
| CVE-2020-12352 | 3 Bluez, Linux, Redhat | 8 Bluez, Linux Kernel, Enterprise Linux and 5 more | 2024-11-21 | 6.5 Medium |
| Improper access control in BlueZ may allow an unauthenticated user to potentially enable information disclosure via adjacent access. | ||||
| CVE-2020-0556 | 5 Bluez, Canonical, Debian and 2 more | 5 Bluez, Ubuntu Linux, Debian Linux and 2 more | 2024-11-21 | 7.1 High |
| Improper access control in subsystem for BlueZ before version 5.54 may allow an unauthenticated user to potentially enable escalation of privilege and denial of service via adjacent access | ||||
| CVE-2019-8922 | 3 Bluez, Debian, Linux | 3 Bluez, Debian Linux, Linux Kernel | 2024-11-21 | 8.8 High |
| A heap-based buffer overflow was discovered in bluetoothd in BlueZ through 5.48. There isn't any check on whether there is enough space in the destination buffer. The function simply appends all data passed to it. The values of all attributes that are requested are appended to the output buffer. There are no size checks whatsoever, resulting in a simple heap overflow if one can craft a request where the response is large enough to overflow the preallocated buffer. This issue exists in service_attr_req gets called by process_request (in sdpd-request.c), which also allocates the response buffer. | ||||
| CVE-2019-8921 | 3 Bluez, Debian, Linux | 3 Bluez, Debian Linux, Linux Kernel | 2024-11-21 | 6.5 Medium |
| An issue was discovered in bluetoothd in BlueZ through 5.48. The vulnerability lies in the handling of a SVC_ATTR_REQ by the SDP implementation. By crafting a malicious CSTATE, it is possible to trick the server into returning more bytes than the buffer actually holds, resulting in leaking arbitrary heap data. The root cause can be found in the function service_attr_req of sdpd-request.c. The server does not check whether the CSTATE data is the same in consecutive requests, and instead simply trusts that it is the same. | ||||
| CVE-2018-10910 | 3 Bluez, Canonical, Redhat | 3 Bluez, Ubuntu Linux, Enterprise Linux | 2024-11-21 | N/A |
| A bug in Bluez may allow for the Bluetooth Discoverable state being set to on when no Bluetooth agent is registered with the system. This situation could lead to the unauthorized pairing of certain Bluetooth devices without any form of authentication. Versions before bluez 5.51 are vulnerable. | ||||
