      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nserial: 8250: Fix TX deadlock when using DMA\n\n`dmaengine_terminate_async` does not guarantee that the\n`__dma_tx_complete` callback will run. The callback is currently the\nonly place where `dma->tx_running` gets cleared. If the transaction is\ncanceled and the callback never runs, then `dma->tx_running` will never\nget cleared and we will never schedule new TX DMA transactions again.\n\nThis change makes it so we clear `dma->tx_running` after we terminate\nthe DMA transaction. This is \"safe\" because `serial8250_tx_dma_flush`\nis holding the UART port lock. The first thing the callback does is also\ngrab the UART port lock, so access to `dma->tx_running` is serialized.",
