CVE-2017-13693 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
