In the Linux kernel, the following vulnerability has been resolved:

powerpc/memhotplug: Add add_pages override for PPC

With commit ffa0b64e3be5 ("powerpc: Fix virt_addr_valid() for 64-bit Book3E & 32-bit") the kernel now validate the addr against high_memory value. This results in the below BUG_ON with dax pfns.
