hci_le_create_big_complete_evt() iterates over BT_BOUND connections
for a BIG handle using a while loop, accessing ev->bis_handle[i++]
on each iteration. However, there is no check that i < ev->num_bis
before the array access.
When a controller sends a LE_Create_BIG_Complete event with num_bis=0
while BT_BOUND connections exist for that BIG handle, the loop reads
beyond the valid bis_handle[] entries into adjacent heap memory.
Since the out-of-bounds values typically exceed HCI_CONN_HANDLE_MAX
(0x0EFF), hci_conn_set_handle() rejects them and the connection
remains in BT_BOUND state. The same connection is then found again
by hci_conn_hash_lookup_big_state(), creating an infinite loop with
hci_dev_lock held that blocks all Bluetooth operations:
Bluetooth: hci0: Invalid handle: 0x6b6b > 0x0eff
Bluetooth: hci0: Invalid handle: 0x6b6b > 0x0eff
... (repeats ~177 times)
Bluetooth: hci0: Opcode 0x2040 failed: -110
Bluetooth: hci0: command 0x2040 tx timeout
The value 0x6b6b is the KASAN slab free poison byte (0x6b),
confirming reads of freed/uninitialized heap memory.
Fix this by adding a bounds check on i against ev->num_bis before
accessing the array. Connections beyond the reported count are
cleaned up with HCI_ERROR_UNSPECIFIED to prevent the infinite loop.

Actually we might want to consider that all BISes failed if something
like this happens, so perhaps we should break and terminate if i !=
ev->num_bis

hci_le_create_big_complete_evt() iterates over BT_BOUND connections for
a BIG handle using a while loop, accessing ev->bis_handle[i++] on each
iteration. However, there is no check that i stays within ev->num_bis
before the array access.
When a controller sends a LE_Create_BIG_Complete event with fewer
bis_handle entries than there are BT_BOUND connections for that BIG,
or with num_bis=0, the loop reads beyond the valid bis_handle[] flex
array into adjacent heap memory. Since the out-of-bounds values
typically exceed HCI_CONN_HANDLE_MAX (0x0EFF), hci_conn_set_handle()
rejects them and the connection remains in BT_BOUND state. The same
connection is then found again by hci_conn_hash_lookup_big_state(),
creating an infinite loop with hci_dev_lock held.
Fix this by:
- Breaking out of the loop when i reaches ev->num_bis and cleaning
up all remaining BT_BOUND connections, then terminating the BIG
since a mismatch between the host and controller state indicates
failure.
- Properly cleaning up the connection when hci_conn_set_handle()
fails, instead of calling continue which leaves it in BT_BOUND
state where it would be found again by the same lookup on the
next iteration.

From: ZhiTao Ou <hkbinbinbin@gmail.com>
hci_le_create_big_complete_evt() iterates over BT_BOUND connections for
a BIG handle using a while loop, accessing ev->bis_handle[i++] on each
iteration. However, there is no check that i stays within ev->num_bis
before the array access.
When a controller sends a LE_Create_BIG_Complete event with fewer
bis_handle entries than there are BT_BOUND connections for that BIG,
or with num_bis=0, the loop reads beyond the valid bis_handle[] flex
array into adjacent heap memory. Since the out-of-bounds values
typically exceed HCI_CONN_HANDLE_MAX (0x0EFF), hci_conn_set_handle()
rejects them and the connection remains in BT_BOUND state. The same
connection is then found again by hci_conn_hash_lookup_big_state(),
creating an infinite loop with hci_dev_lock held.
Fix this by:
- Breaking out of the loop when i reaches ev->num_bis and cleaning
up all remaining BT_BOUND connections, then terminating the BIG
since a mismatch between the host and controller state indicates
failure.
- Properly cleaning up the connection when hci_conn_set_handle()
fails, instead of calling continue which leaves it in BT_BOUND
state where it would be found again by the same lookup on the
next iteration.
Fixes: a0bfde167b50 ("Bluetooth: ISO: Add support for connecting multiple BISes")
