CVE-2017-13693  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 4.12.10 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. The acpi_ds_create_operands() function in drivers/acpi/acpica/dsutils.c in the Linux kernel through 4.12.9 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.
