The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Bluetooth: btusb: validate Realtek vendor event length btusbrecveventrealtek reads the event code at data0 and the Realtek subevent code at data2 before decidin...

CVE-2026-66875

In the Mira hormone monitor device firmware v1.7.1.47 build 01070147, a remote unauthenticated attacker within BLE range approximately 10–30 meters can silently rebind the device to an attacker-controlled account, extract stored hormone measurements in cleartext, cause a denial-of-service via...

CVE-2026-66875

The CVE-2026-66875 entry concerns the Mira hormone monitor firmware v1.7.1.47 (build 01070147). A remote unauthenticated attacker within BLE range (≈10–30 m) can: rebind the device to an attacker-controlled account; extract stored hormone measurements in cleartext; cause a denial-of-service via m...

CVE-2026-18844

The CVE-2026-18844 entry concerns the Pulsetto Vagus Nerve Stimulator firmware, where several undisclosed commands are accepted over BLE without authentication or encryption and are fully processed when powered on. The connected sources offer no details on affected software versions, specific com...

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-2026-68389

A flaw was found in the Bluetooth Host Controller Interface HCI Qualcomm Atheros QCA driver within the Linux kernel. This vulnerability occurs when the controller reports an invalid zero memory dump size, leading to improper state cleanup. An attacker could potentially exploit this to cause memor...

CVE-2026-68394

A flaw was found in the Bluetooth Management MGMT component of the Linux kernel. A use-after-free vulnerability occurs when the MGMTOPLOADCONNPARAM operation queues a connection update. If a subsequent request frees the associated memory before the update is processed, it can lead to a system cra...

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...

CVE-2026-68188

A flaw was found in the Linux kernel's Bluetooth RFCOMM subsystem. A race condition in the rfcommttysettermios function allows a session to be freed while it is still actively in use. This use-after-free UAF vulnerability can be exploited by a local attacker. Successful exploitation leads to a...

CVE-2026-68391

A flaw was found in the Linux kernel's Bluetooth management component. This vulnerability involves a Use-After-Free UAF condition, a type of memory corruption where the system attempts to use memory after it has been freed. This can occur due to improper handling of hciconn pointers, potentially...

CVE-2026-68189

A flaw was found in the Bluetooth hcisync component of the Linux kernel. A race condition during the UUID list traversal, caused by improper synchronization between asynchronous command sync work and UUID list updates, can lead to a use-after-free vulnerability. This could allow a local attacker ...

CVE-2026-68390

A flaw was found in the Linux kernel's Bluetooth subsystem, specifically within the hcisync component. This vulnerability occurs because the hciconnparamslookup function does not properly hold a necessary lock hdev-lock during operations. This oversight can lead to unsafe list iterations or...

CVE-2026-68085

A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI Universal Asynchronous Receiver/Transmitter UART driver. This vulnerability occurs when a Bluetooth device is reopened after a pending write operation was canceled, but an internal flag indicating a pending write is no...

CVE-2026-11894

The Realtek BEE Bluetooth HCI driver's send callback, bthcibeesend in drivers/bluetooth/hci/hcibee.c, violated the bthcidriverapi buffer-ownership contract. That contract requires the driver to consume unref the transmit netbuf only on success; on an error return the host caller retains ownership...

CVE-2026-11893

The Bluetooth HCI driver for Bouffalo Lab on-chip BLE controllers BL60x/BL70x/BL61x, btbflbsend in drivers/bluetooth/hci/hcibflb.c, violates the bthcidriverapi.send buffer-ownership contract. That contract documented at include/zephyr/drivers/bluetooth.h requires the buffer reference to be consum...

CVE-2026-11894

The Realtek BEE Bluetooth HCI driver's send callback, bthcibeesend in drivers/bluetooth/hci/hcibee.c, violated the bthcidriverapi buffer-ownership contract. That contract requires the driver to consume unref the transmit netbuf only on success; on an error return the host caller retains ownership...

CVE-2026-11894 Double-free / use-after-free in Realtek BEE Bluetooth HCI driver `send()` error paths

The Realtek BEE Bluetooth HCI driver's send callback, bthcibeesend in drivers/bluetooth/hci/hcibee.c, violated the bthcidriverapi buffer-ownership contract. That contract requires the driver to consume unref the transmit netbuf only on success; on an error return the host caller retains ownership...

CVE-2026-11894

The CVE-2026-11894 entry concerns Realtek’s BEE Bluetooth HCI driver (bt_hci_bee_send in drivers/bluetooth/hci/hci_bee.c). The vulnerability arises from violating the bt_hci_driver_api buffer-ownership contract: on error, the host should retain and unref the transmit net_buf, but the pre-fix code...
