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...

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.

CVE-2026-11893

The CVE concerns Bouffalo Lab on‑chip BLE controllers (BL60x/BL70x/BL61x) with Zephyr’s Bluetooth HCI, where bt_bflb_send() in hci_bflb.c violates the bt_hci_driver_api.send() buffer-ownership contract. On error, the driver unrefs the buffer, but the host TX path (send_buf() in subsys/bluetooth/h...

PT-2026-80712

Several methods in circular-buffer drop elements before updating the buffer's start/end metadata. If an element's Drop panics during the drop, the metadata update is skipped, so the buffer still treats the already-dropped elements as live. When the buffer is later dropped or used after the panic ...
