ROS-20261006-73-0091

The vulnerability of the functions sessionfree, hidpsessionRemove, and hidpSessionThread in the net/bluetooth/hidp/core.c module of the Linux kernel’s Bluetooth subsystem is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to cause a...

CVE-2026-90255

A flaw was found in the Linux kernel's Bluetooth subsystem. Specifically, a resource leak occurs in the handling of Synchronous Connection-Oriented SCO setup contexts. If a setup entry is cancelled, its associated context is not properly released, leading to a memory leak. This issue could also...

ROS-20261005-73-0037

The vulnerability of the l2capecredconnreq function in the net/bluetooth/l2capcore.c module of the Linux kernel’s Bluetooth subsystem is related to a numerical overflow issue. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of...

CVE-2026-97975

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition occurs when child network devices are unregistered concurrently while Bluetooth connection cleanup routines reparent child devices. A local user can exploit this timing issue to trigger a NULL pointer dereference,...

CVE-2026-97408

A flaw was found in the Linux kernel's Bluetooth subsystem. The Logical Link Control and Adaptation Protocol L2CAP implementation fails to properly validate the payload length of connectionless frames before reading the Protocol/Service Multiplexer PSM field. 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-20260928-73-0094

The vulnerability of the scosockkill function in the net/bluetooth/sco.c module of the Linux Bluetooth subsystem is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the...

ROS-20260928-73-0080

The vulnerability of the recvpkt function in the net/bluetooth/6lowpan.c module of the Linux Bluetooth subsystem is related to the improper disabling or release of resources. Exploiting this vulnerability could allow a malicious actor to cause service failure remotely...

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...

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...

PT-2026-94602

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the Bluetooth subsystem when adv timeout expire passes a memory instance allocated via kmalloc to hci cmd sync queue without a destroy callback. This leads to...

Astra Linux – Vulnerability in Linux 5.10, Linux

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.
