Upgrade Debian:8 linux-4.9 to version 4.9.110-1~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.
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
