  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HCI: Fix global-out-of-
    bounds To loop a variable-length array, hci_init_stage_sync(stage) considers that stage[i] is valid as
    long as stage[i-1].func is valid. Thus, the last element of stage[].func should be intentionally invalid
    as hci_init0[], le_init2[], and others did. However, amp_init1[] and amp_init2[] have no invalid element,
    letting hci_init_stage_sync() keep accessing amp_init1[] over its valid range. This patch fixes this by
    adding {} in the last of amp_init1[] and amp_init2[].
