How to fix?

Upgrade Debian:8 linux-4.9 to version 4.9.168-1+deb9u5~deb8u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-4.9 package and not the linux-4.9 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.
