Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails
The spi controller supports 44-bit address space on AXI in DMA mode, so set dma_addr_t width to 44-bit to avoid using a swiotlb mapping. In addition, if dma_map_single fails, it should return immediately instead of continuing doing the DMA operation which bases on invalid address.
This fixes the following crash which occurs in reading a big block from flash:
