CVE-2017-13695 (opens in a new tab)How to fix?
Upgrade SLES:15.1 kernel-obs-build to version 4.12.14-150100.197.114.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-obs-build package and not the kernel-obs-build package as distributed by SLES.
See How to fix? for SLES:15.1 relevant fixed versions and status.
The acpi_ns_evaluate() function in drivers/acpi/acpica/nseval.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.
