CVE-2022-50625

CVE-2022-50625 is a Linux kernel issue where the SBSA UART path could access the DMACR register in the PL011 driver when DMA is used, potentially causing a data abort and guest segfaults in Xen environments. The fix adds a using_rx_dma check in pl011_dma_rx_stop to avoid DMACR access for SBSA UAR...
