CVE-2026-68085

CVE-2026-68085 — Linux kernel (Bluetooth hci_uart) Root cause: when canceling a pending write_work in hci_uart_close(), the HCI_UART_SENDING flag is not cleared, causing future writes to be blocked when the device is reopened. The fix clears HCI_UART_SENDING on cancellation and makes tx_skb handl...
