CVE-2018-1118
Published: 10 May 2018
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.
From the Ubuntu Security Team
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).
