In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
Bluetooth: ISO: fix malformed ISO_END\/CONT handling<\/p>\n
Core specification (Part C vol 4 sec 5.4.5) does not exclude empty
\nISO_CONT, ISO_END packets. We currently reject them if they are last.<\/p>\n
If controller sends malformed sequence<\/p>\n
ISO_START -> rx_len = 4, ISO_CONT skb->len 4, ISO_START<\/p>\n
that ends payload in ISO_CONT, we leak conn->rx_skb. If controller sends
\ntoo long ISO_END, we panic on skb_put. If controller sends too short
\nISO_END we accept it.<\/p>\n
Fix by marking unfinished ISO_START via conn->rx_skb != NULL. Check
\nskb->len properly before skb_put. Combine the ISO_CONT\/END code paths
\nas they require the same initial checks. Reject too short ISO_END
