Vulnerability Details : CVE-2021-47134
In the Linux kernel, the following vulnerability has been resolved:
efi/fdt: fix panic when no valid fdt found
setup_arch() would invoke efi_init()->efi_get_fdt_params(). If no
valid fdt found then initial_boot_params will be null. So we
should stop further fdt processing here. I encountered this
issue on risc-v.
