  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: ISO: drop ISO_END frames received without prior ISO_START\n\nISO data PDUs carry a packet-boundary flag indicating START, CONT, END\nor SINGLE. The ISO_CONT branch of iso_recv() guards against a missing\nISO_START by checking conn-\u003erx_len before touching conn-\u003erx_skb, but\nISO_END does not.\n\nIf a peer sends an ISO_END as the first packet on a fresh ISO\nconnection, conn-\u003erx_skb is still NULL and conn-\u003erx_len is zero, so\nskb_put(conn-\u003erx_skb, ...) dereferences NULL and oopses. For BIS,\nwhere receivers sync to a broadcaster without pairing, any broadcaster\non the air can trigger this.\n\nMirror the ISO_CONT check at the top of ISO_END so a stray end fragment\nis logged and dropped instead of crashing the host.",
