NVD Description
Note: Versions mentioned in the description apply only to the upstream acpica-unix package and not the acpica-unix package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
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.
