Severity ?
2.3 (Low) - CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N
Summary
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.
