CVE-2022-50375

CVE-2022-50375 affects the Linux kernel: the fix ensures that in lpuart_dma_shutdown the flags for lpuart_dma_tx_use and lpuart_dma_rx_use are set to false. Without this, lpuart_flush_buffer could access DMA APIs after DMA teardown, causing aborts. The patch prevents DMA access after relinquishme...
