CVE-2017-13695
Published: 25 August 2017
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.
From the Ubuntu Security Team
Seunghun Han discovered an information leak in the ACPI handling code in the Linux kernel when handling early termination of ACPI table loading. A local attacker could use this to expose sensitive informal (kernel address locations).
