CVE-2017-13695 (opens in a new tab)How to fix?
There is no fixed version for Centos:7 kernel-rt-trace-kvm.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace-kvm package and not the kernel-rt-trace-kvm package as distributed by Centos.
See How to fix? for Centos:7 relevant fixed versions and status.
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.
