  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: ISO: drop ISO_END frames received without prior ISO_START  ISO data PDUs carry a packet-boundary flag indicating START, CONT, END or SINGLE. The ISO_CONT branch of iso_recv() guards against a missing ISO_START by checking conn-\u003erx_len before touching conn-\u003erx_skb, but ISO_END does not.  If a peer sends an ISO_END as the first packet on a fresh ISO connection, conn-\u003erx_skb is still NULL and conn-\u003erx_len is zero, so skb_put(conn-\u003erx_skb, ...) dereferences NULL and oopses. For BIS, where receivers sync to a broadcaster without pairing, any broadcaster on the air can trigger this.  Mirror the ISO_CONT check at the top of ISO_END so a stray end fragment is logged and dropped instead of crashing the host.",
