kernel: Bluetooth: mgmt: hold reference for hci_conn in mgmt_pending_cmds

A flaw was found in the Linux kernel's Bluetooth management component. This vulnerability involves a Use-After-Free UAF condition, a type of memory corruption where the system attempts to use memory after it has been freed. This can occur due to improper handling of hciconn pointers, potentially...
