      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: mgmt: fix race in read_unconf_index_list()\n\nread_unconf_index_list() counts unconfigured controllers before allocating\nits response, then checks the device flags again while filling it.\n\nhci_dev_list_lock stabilizes list membership, but it does not serialize the\nper-device flags. During asynchronous controller setup, the worker can set\nHCI_UNCONFIGURED and clear HCI_SETUP between the two passes. A controller\nomitted from the allocation count can then become eligible for the fill\npass, causing an out-of-bounds write to rp->index[].\n\nAllocate space for every device on hci_dev_list. Since list membership\ncannot change while hci_dev_list_lock is held, the response remains large\nenough regardless of flag transitions. The reported count and response\nlength still include only eligible unconfigured controllers.",
