"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: RFCOMM: free the skb when the DLC has no owner\n\nrfcomm_recv_data() hands the skb to d->data_ready() and returns 0\nwithout freeing it, so the callback owns the skb from that point on.\nThe tty implementation frees it when the DLC has been detached from its\ndevice:\n\n static void rfcomm_dev_data_ready(struct rfcomm_dlc *dlc,\n struct sk_buff *skb)\n {\n struct rfcomm_dev *dev = dlc->owner;\n\n if (!dev) {\n kfree_skb(skb);\n return;\n }\n\nThe socket implementation returns without freeing it, and the skb is\nleaked.\n\nA connected DLC can have no owner: rfcomm_sock_destruct() clears\nd->owner, while the DLC itself stays on the session until it is closed.\nData frames that arrive in that window still find d->state ==\nBT_CONNECTED in rfcomm_recv_data() and are handed to the callback, one\nleaked skb each.\n\nThe leak does not stop on its own either. The remote runs out of\ncredits only once RFCOMM_RX_THROTTLED is set, and for a socket the only\nplace that sets it is rfcomm_sk_data_ready() itself, below the return.\nrfcomm_process_dlcs() keeps granting credits, so the remote keeps\nsending and the leak keeps growing.\n\nFree the skb, as the tty side does."
