CVE-2026-53073

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcildisc: Clear HCIUARTPROTOINIT on error When hciregisterdev fails in hciuartregisterdev HCIUARTPROTOINIT is not cleared before calling hu-proto-closehu and setting hu-hdev to NULL. This means incoming UART data will...

CVE-2026-53073

CVE-2026-53073 concerns the Linux kernel Bluetooth HCI LDISC: when hci_register_dev() fails in hci_uart_register_dev(), HCI_UART_PROTO_INIT wasn’t cleared before closing and NULLing the HCI device, allowing incoming UART data to reach the protocol recv path after resources are freed. The fix adds...
