CVE-2017-13694

Priority
Description
The acpi_ps_complete_final_op() function in drivers/acpi/acpica/psobject.c
in the Linux kernel through 4.12.9 does not flush the node and node_ext
caches 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.
Notes
tyhicksAs of 17.04, KASLR is not yet enabled by default in Ubuntu
See the patchwork.k.o reference for a possible fix. As of 2017-08-25,
it has not yet been merged upstream.
