In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: ISO: fix malformed ISO_END/CONT handling

Core specification (Part C vol 4 sec 5.4.5) does not exclude empty ISO_CONT, ISO_END packets. We currently reject them if they are last.

If controller sends malformed sequence

ISO_START -> rx_len = 4, ISO_CONT skb->len 4, ISO_START

that ends payload in ISO_CONT, we leak conn->rx_skb. If controller sends too long ISO_END, we panic on skb_put. If controller sends too short ISO_END we accept it.

Fix by marking unfinished ISO_START via conn->rx_skb != NULL. Check skb->len properly before skb_put. Combine the ISO_CONT/END code paths as they require the same initial checks. Reject too short ISO_END packets.
