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.

CVE-2017-13694 [MEDIUM] CWE-200 kernel: ACPI node and node_ext cache leak
kernel: ACPI node and node_ext cache leak
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.
The ACPI parsing functionality in the Linux kernel does not flush the node and node_ext caches which causes a kernel stack dump. This allows local users to obtain sensitive information from kernel
memory and use this information to bypass the KASLR protection mechanism by creating and applying crafted ACPI table.
