An adjacent attacker within Bluetooth...

CVE-2026-98109

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition occurs during device registration when background initialization tasks execute before internal structures and locks are fully prepared. A local user can trigger this issue during device setup, causing the system to attem...

CVE-2026-98108

A flaw was found in the Linux kernel's Bluetooth subsystem. When processing Bluetooth Low Energy connection requests in the Logical Link Control and Adaptation Protocol L2CAP layer, channel modes are incorrectly assigned during deferred connection handling. A nearby attacker within Bluetooth rang...

CVE-2026-98107

A flaw was found in the Linux kernel's Bluetooth subsystem. A local user can trigger an out-of-bounds memory write by establishing multiple concurrent Logical Link Control and Adaptation Protocol L2CAP connections. Due to improper channel limit verification, this flaw allows memory corruption tha...

ROS-20260925-73-0068

The vulnerability of the hidpsettimer function in the net/bluetooth/hidp/core.c module of the Linux kernel’s Bluetooth subsystem is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility...

kernel: Bluetooth: serialize accept_q access

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the handling of the acceptq within the btsockpoll function due to a lack of synchronization. This could allow a local attacker to cause a denial of service by manipulating socket operations during child teardow...

kernel: Bluetooth: serialize accept_q access

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the handling of the acceptq within the btsockpoll function due to a lack of synchronization. This could allow a local attacker to cause a denial of service by manipulating socket operations during child teardow...

kernel: Linux kernel Bluetooth: Denial of Service via race condition in hidp_session_thread

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition in the hidpsessionthread can lead to a use-after-free vulnerability. This occurs when a timer is active while its deletion function is called, causing memory to be accessed after it has been freed. A local attacker could...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisysfs: Fixed an issue where the function deviceadd was called multiple times. The function deviceadd should not be called multiple times, as stated in its documentation: “Do not call this routine or deviceregister...

kernel: Bluetooth: fix locking in hci_conn_request_evt() with HCI_PROTO_DEFER

A flaw was found in the Linux kernel's Bluetooth subsystem. Improper handling of locking within the hciconnrequestevt function, particularly when the HCIPROTODEFER protocol is active, can result in a Use-After-Free UAF vulnerability. This condition arises when a connection object is accessed afte...

kernel: Bluetooth: hci_sync: fix UAF in hci_le_create_cis_sync

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, allows an attacker to access memory after it has been freed. This can lead to a system crash, resulting in a Denial of Service DoS, or potentially enable an attacker to execute malicious code. Th...

CVE-2026-89583

A flaw was found in the Linux kernel's Bluetooth subsystem. An out-of-bounds OOB read vulnerability exists in the eirgetservicedata function due to incorrect length calculation when parsing Extended Inquiry Response EIR advertising data. A remote attacker, by sending a specially crafted periodic...

kernel: Bluetooth: hci_event: fix potential UAF in SSP passkey handlers

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, exists within the Secure Simple Pairing SSP passkey handlers. It occurs when hciconn lookup and field access are performed without proper locking, allowing a connection to be freed concurrently...
