ACPI Operand Cache Flushing Vulnerability

CVE-2017-13695 · LOW Severity

AV:L/AC:L/AU:N/C:P/I:N/A:N

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.
