Descriptions
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.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: efi/fdt: corrige el pánico cuando no se encuentra un fdt válido. setup_arch() invocaría efi_init()->efi_get_fdt_params(). Si no se encuentra un fdt válido, inicial_boot_params será nulo. Por lo tanto, deberíamos detener el procesamiento adicional de fdt aquí. Encontré este problema en risc-v.
