"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_core: Serialize fragmented ISO packet queueing\n\nThe fragmented path in hci_queue_iso() calls __skb_queue_tail() without\nholding conn->data_q.lock. The socket lock serializes senders, but the\ntransmit worker can concurrently remove packets from this queue using\nskb_dequeue().\n\nAfter an insertion saves the old tail pointer, hci_sched_iso() can dequeue\nthat packet and pass it to the driver. The driver can free the packet\nbefore the insertion resumes and writes to the old tail's next pointer,\ncausing a use-after-free. Concurrent updates can also corrupt the queue.\n\nKASAN reported:\n\n BUG: KASAN: slab-use-after-free in hci_send_iso+0xc7d/0xe10\n Call Trace:\n hci_send_iso+0xc7d/0xe10\n iso_sock_sendmsg+0x710/0x900\n __sys_sendto+0x34a/0x3a0\n\n Allocated by task 86:\n __alloc_skb+0xdd/0x820\n alloc_skb_with_frags+0x7e/0x770\n sock_alloc_send_pskb+0x67a/0x820\n bt_skb_sendmsg.constprop.0+0xc0/0x6c0\n iso_sock_sendmsg+0x44e/0x900\n\n Freed by task 90:\n kmem_cache_free+0xcb/0x3d0\n vhci_read+0x33f/0x4d0\n vfs_read+0x177/0xa20\n\nHold the queue lock across the entire fragment batch, as hci_queue_acl()\ndoes, to serialize insertion against dequeue while preserving fragment\nordering."
