CVE-2026-46111

The CVE concerns a use-after-free in the Linux kernel Bluetooth stack (hci_conn, BIG creation). The patch adds hci_conn_valid() in create_big_sync() to detect stale connections before BIG creation, handles -ECANCELED in create_big_complete(), and re-validates under hci_dev_lock() before dereferen...
