A flaw was found in the Linux kernel's i3c: mipi-i3c-hci module. A race condition in the `hci_dma_dequeue_xfer()` function allows parallel calls to interfere with each other when multiple transfers time out concurrently. This interference can cause the DMA ring to stop or restart unexpectedly, potentially leading to system instability or a denial of service (DoS).
