  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: ISO: fix malformed ISO_END/CONT handling\n\nCore 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.\n\nIf controller sends malformed sequence\n\n    ISO_START -\u003e rx_len = 4, ISO_CONT skb-\u003elen 4, ISO_START\n\nthat ends payload in ISO_CONT, we leak conn-\u003erx_skb. If controller sends\ntoo long ISO_END, we panic on skb_put. If controller sends too short\nISO_END we accept it.\n\nFix by marking unfinished ISO_START via conn-\u003erx_skb != NULL.  Check\nskb-\u003elen properly before skb_put.  Combine the ISO_CONT/END code paths\nas they require the same initial checks. Reject too short ISO_END\npackets.",
