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...

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: 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...

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...

CVE-2026-74530

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, occurs when a connection is prematurely released while a related synchronization task in hciconnectbigsync is still running. This theoretical flaw could allow an attacker to cause a system crash...

CVE-2026-74509

A flaw was found in the Linux kernel's Bluetooth subsystem. Specifically, the hcisync component, which manages Bluetooth advertising data, is susceptible to a Use-After-Free UAF vulnerability. This occurs when a pointer to advertising data becomes invalid but is still accessed, particularly durin...

CVE-2026-74303

A flaw was found in the Linux kernel's Bluetooth subsystem. The qcadmphdr function, when handling non-serdev devices, attempts to dereference a NULL pointer without proper validation. An attacker could potentially trigger this condition, leading to a system crash and a denial of service...

CVE-2026-74302

A flaw was found in the Bluetooth subsystem of the Linux kernel. During the unregistration of a Bluetooth device, the system fails to properly disable timers before freeing the associated memory. This can lead to a use-after-free vulnerability, where the system attempts to access memory that has...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Bluetooth: MGMT: Fix adv monitor add failure cleanup hciaddadvmonitor publishes a new advmonitor in hdev-advmonitorsidr before the powered MSFT setup step. The...

CVE-2026-74528

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a use-after-free, occurs when the hcisync component improperly handles connection references, leading to the potential reuse and access of freed memory pointers. A remote attacker could exploit this to cause system...

CVE-2026-74533

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix race of kfree vs krefgetunlesszero hciconn::isodata is accessed and modified without lock or RCU. This leads to a race Task hdev-workqueue Task 2 isorecv isoconnputconn conn = LOAD hcon-isodata isoconnfreeconn...

Linux Distros Unpatched Vulnerability : CVE-2026-74538

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Bluetooth: ISO: lock sk in isoconnectind Accessing isopisk-conn requires locksock, which is not taken in the ev3 part of isoconnectind. It may also be NULL if...

CVE-2026-68339

A flaw was found in the Linux kernel's Bluetooth subsystem btusb driver. An attacker could craft a two-byte vendor event that, due to improper validation of the Realtek vendor event length in the btusbrecveventrealtek function, could lead to the system attempting to read a non-existent third byte...

CVE-2026-68392

A flaw was found in the Linux kernel's Bluetooth management subsystem. This vulnerability occurs due to incorrect locking when handling memory pointers during device unpairing and disconnection. An attacker could exploit this to trigger a Use-After-Free UAF condition, which is a type of memory...
