CVE-2019-8922	Hig	0.57	8.8	0.00	Nov 29, 2021	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-2016-7837	Hig	0.51	7.8	0.01	Jun 9, 2017	Buffer overflow in BlueZ 5.41 and earlier allows an attacker to execute arbitrary code via the parse_line function used in some userland utilities.
CVE-2022-39177	Hig	0.50	8.8	0.00	Sep 2, 2022	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	Hig	0.50	8.8	0.00	Sep 2, 2022	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	Hig	0.50	8.8	0.00	Mar 10, 2022	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-2020-27153	Hig	0.49	8.6	0.02	Oct 15, 2020	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-2016-9918	Hig	0.49	7.5	0.00	Dec 8, 2016	In BlueZ 5.42, an out-of-bounds read was identified in "packet_hexdump" function in "monitor/packet.c" source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.
CVE-2019-8921	Med	0.42	6.5	0.00	Nov 29, 2021	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-2021-3658	Med	0.35	6.5	0.00	Mar 2, 2022	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-2016-9804	Med	0.34	5.3	0.00	Dec 3, 2016	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	Med	0.34	5.3	0.00	Dec 3, 2016	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-2016-9802	Med	0.34	5.3	0.00	Dec 3, 2016	In BlueZ 5.42, a buffer over-read was identified in "l2cap_packet" function in "monitor/packet.c" source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.
CVE-2016-9801	Med	0.34	5.3	0.00	Dec 3, 2016	In BlueZ 5.42, a buffer overflow was observed in "set_ext_ctrl" function in "tools/parser/l2cap.c" source file when processing corrupted dump file.
CVE-2016-9800	Med	0.34	5.3	0.00	Dec 3, 2016	In BlueZ 5.42, a buffer overflow was observed in "pin_code_reply_dump" function in "tools/parser/hci.c" source file. The issue exists because "pin" array is overflowed by supplied parameter due to lack of boundary checks on size of the buffer from frame "pin_code_reply_cp *cp" parameter.
CVE-2016-9799	Med	0.34	5.3	0.00	Dec 3, 2016	In BlueZ 5.42, a buffer overflow was observed in "pklg_read_hci" function in "btsnoop.c" source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.
CVE-2016-9798	Med	0.34	5.3	0.00	Dec 3, 2016	In BlueZ 5.42, a use-after-free was identified in "conf_opt" function in "tools/parser/l2cap.c" source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.
CVE-2016-9797	Med	0.34	5.3	0.00	Dec 3, 2016	In BlueZ 5.42, a buffer over-read was observed in "l2cap_dump" function in "tools/parser/l2cap.c" source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.
CVE-2006-6899		0.04	—	0.10	Dec 31, 2006	hidd in BlueZ (bluez-utils) before 2.25 allows remote attackers to obtain control of the (1) Mouse and (2) Keyboard Human Interface Device (HID) via a certain configuration of two HID (PSM) endpoints, operating as a server, aka HidAttack.
CVE-2024-8805		0.00	—	0.03	Nov 22, 2024	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-2023-51596		0.00	—	0.03	May 3, 2024	BlueZ Phone Book Access Profile Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device. The specific flaw exists within the handling of the Phone Book Access profile. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20939.
