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...

CVE-2026-11893 Double free / use-after-free in Bouffalo Lab HCI driver send() error paths (hci_bflb)

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-2026-20495

CVE-2026-20495 involves a Bluetooth driver with a missing permission check that enables local escalation of privilege. The vulnerability could be exploited locally with low privileges and no user interaction, potentially compromising confidentiality, integrity, and availability. The documented re...

CVE-2026-64549

A flaw was found in the Linux kernel's Bluetooth bpa10x driver. This vulnerability allows a malicious Bluetooth device to trigger an out-of-bounds read in the bpa10xsetup function by sending a specially crafted one-byte or non-NUL-terminated response. This can lead to information disclosure, wher...

CVE-2026-64407

A flaw was found in the Linux kernel's Bluetooth driver. A malicious Bluetooth controller could send a specially crafted firmware download request that causes an out-of-bounds read. This allows the driver to read memory beyond the intended firmware data and send it back over the Universal...

CVE-2026-64409

A flaw was found in the Linux kernel's Bluetooth MTK SDIO btmtksdio driver. An incorrect timeout check in the btmtksdiotxrxwork function can lead to an infinite loop. This prevents the loop from terminating and releasing the SDIO host, resulting in a denial of service DoS where the system resourc...

The vulnerability of the btusb_mtk_claim_iso_intf() function in the drivers/bluetooth/btusb.c module of the Linux Bluetooth kernel driver allows a hacker to cause a service failure.

The vulnerability of the btusbmtkclaimisointf function in the drivers/bluetooth/btusb.c module of the Linux Bluetooth device driver relates to pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

The vulnerability of the btusb_disconnect() function in the drivers/bluetooth/btusb.c module of the Linux Bluetooth device driver allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the btusbdisconnect function in the drivers/bluetooth/btusb.c module of the Linux Bluetooth device driver framework is related to the reutilization of previously freed memory.
