  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ni3c: mipi-i3c-hci: Fix race in DMA ring dequeue\n\nThe HCI DMA dequeue path (hci_dma_dequeue_xfer()) may be invoked for\nmultiple transfers that timeout around the same time.  However, the\nfunction is not serialized and can race with itself.\n\nWhen a timeout occurs, hci_dma_dequeue_xfer() stops the ring, processes\nincomplete transfers, and then restarts the ring.  If another timeout\ntriggers a parallel call into the same function, the two instances may\ninterfere with each other - stopping or restarting the ring at unexpected\ntimes.\n\nAdd a mutex so that hci_dma_dequeue_xfer() is serialized with respect to\nitself.",
