The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the
Linux kernel before 4.12 does not flush the operand cache and causes a
kernel stack dump, which allows local users to obtain sensitive information
from kernel memory and bypass the KASLR protection mechanism (in the kernel
through 4.9) via a crafted ACPI table.
