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.

Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the VirtIO subsystem in the Linux kernel did not
properly initialize memory in some situations. A local attacker could use
this to possibly expose sensitive information (kernel memory).

CVE-2018-1118 [LOW] vhost: fix info leak due to uninitialized memory
vhost: fix info leak due to uninitialized memory
struct vhost_msg within struct vhost_msg_node is copied to userspace.
Unfortunately it turns out on 64 bit systems vhost_msg has padding after
type which gcc doesn't initialize, leaking 4 uninitialized bytes to
userspace.
This padding also unfortunately means 32 bit users of this interface are
broken on a 64 bit kernel which will need to be fixed separately.
