kernel: use-after-free in net/bluetooth/hci_event.c when destroying an hci_chan

A use-after-free flaw was found in hcisendacl in the bluetooth host controller interface HCI in Linux kernel, where a local attacker with an access rights could cause a denial of service problem on the system The issue results from the object hchan, freed in hcidisconnloglinkcompleteevt, yet stil...

Google Warns of Zero-Click Bluetooth Flaws in Linux-based Devices

Google security researchers are warning of a new set of zero-click vulnerabilities in the Linux Bluetooth software stack that can allow a nearby unauthenticated, remote attacker to execute arbitrary code with kernel privileges on vulnerable devices. According to security engineer Andy Nguyen, the...

The vulnerabilities of the functions hci_uart_register_dev() and hci_uart_set_proto() in the Linux operating system allow attackers to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerabilities of the functions hciuartregisterdev and hciuartsetproto drivers/bluetooth/hcildisc.c in the Linux operating system are related to the use of memory after it is freed. Exploiting these vulnerabilities could allow an attacker to compromise the confidentiality, integrity, and...

Vulnerability of drivers/bluetooth/hci_ath.c, drivers/bluetooth/hci_bcm.c, drivers/bluetooth/hci_intel.c, drivers/bluetooth/hci_ldisc.c, drivers/bluetooth/hci_mrvl.c, drivers/bluetooth/hci_qca.c, and drivers/bluetooth/hci_uart.h for Linux operating system’s Bluetooth-enabled UART adapters, allowing a hacker to cause a service failure

The vulnerabilities in the drivers/bluetooth/hciath.c, drivers/bluetooth/hcibcm.c, drivers/bluetooth/hciintel.c, drivers/bluetooth/hcildisc.c, drivers/bluetooth/hcimrvl.c, drivers/bluetooth/hciqca.c, and drivers/bluetooth/hciuart.h files for UART-connected Bluetooth adapters in Linux operating...

The vulnerability of the hidp_process_report function in the Bluetooth component of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the hidpprocessreport function in the Bluetooth component of the Linux kernel’s core code is due to a numerical overflow condition. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected informati...

BlueZ buffer overflow vulnerability (CNVD-2016-11951)

BlueZ is an official Bluetooth stack for Linux. A buffer overflow vulnerability exists in the 'setextctrl' function in the tools/parser/l2cap.c source file of BlueZ version 5.42. An attacker can exploit this vulnerability by running a compromised dump file to cause a denial of service...

The vulnerability of the Linux operating system allows a malicious individual to gain access to confidential information from the kernel’s memory.

The vulnerability exists in the Bluetooth subsystem of the Linux kernel due to incorrect initialization of data structures. Exploiting this vulnerability allows local users to access confidential information from the kernel’s memory, using a specially crafted system call called getsockopt. This...

bluez-utils: Bluetooth device name validation vulnerability

Background bluez-utils are the utilities for use with the BlueZ implementation of the Bluetooth wireless standards for Linux. Description The name of a Bluetooth device is improperly validated by the hcid utility when a remote device attempts to pair itself with a computer. Impact An attacker cou...

security flaw

The bluezsockcreate function in the Bluetooth stack for Linux kernel 2.4.6 through 2.4.30-rc1 and 2.6 through 2.6.11.5 allows local users to gain privileges via 1 socket or 2 socketpair call with a negative protocol value...
