The current code dereferences the returned pointer without checking for NULL, leading to a kernel NULL pointer dereference at the following lines: dma_addr = rmem->base; // line 1156 num_desc = div_u64(rmem->size, buf_size); // line 1160 Add a NULL check after of_reserved_mem_lookup() and return -ENODEV if the lookup fails, which is consistent with the existing error handling for of_parse_phandle() failure in the same code block.
