CVE-2026-53364

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: Fix memory leak in hci_le_big_terminate()
hci_le_big_terminate() allocates iso_list_data via kzalloc_obj but returns 0 without freeing it when neither pa_sync_term nor big_sync_term flags are set after evaluating the PA and BIG sync connection state.
This early-return path was introduced when hci_le_big_terminate() was refactored to take struct hci_conn instead of raw u8 parameters, adding PA/BIG flag evaluation logic. The existing kfree() on hci_cmd_sync_queue failure does not cover this path.
