Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> i3c: mipi-i3c-hci: Fix race in DMA ring dequeue<br /> <br /> The HCI DMA dequeue path (hci_dma_dequeue_xfer()) may be invoked for<br /> multiple transfers that timeout around the same time. However, the<br /> function is not serialized and can race with itself.<br /> <br /> When a timeout occurs, hci_dma_dequeue_xfer() stops the ring, processes<br /> incomplete transfers, and then restarts the ring. If another timeout<br /> triggers a parallel call into the same function, the two instances may<br /> interfere with each other - stopping or restarting the ring at unexpected<br /> times.<br /> <br /> Add a mutex so that hci_dma_dequeue_xfer() is serialized with respect to<br /> itself.
