Technical Summary

The Linux kernel Bluetooth subsystem contained a memory leak in the hci_le_big_terminate() function. This function allocates memory for iso_list_data using kzalloc_obj but fails to free it if neither the pa_sync_term nor big_sync_term flags are set after evaluating the PA and BIG sync connection state. The early return path that causes the leak was introduced when the function was refactored to accept a struct hci_conn parameter instead of raw u8 parameters, adding logic to evaluate PA/BIG flags. The existing memory free operation on hci_cmd_sync_queue failure does not cover this new early return path, resulting in a resource leak.
