CVE-2017-13695

MEDIUM

Linux Kernel < 4.12.9 - Information Disclosure via ACPI Table Handling

Title source: llm
STIX 2.1

Description

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.
