Description
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists in the vhost/vhost.c:vhost_new_msg() function due to improper initialization of memory in messages that are passed between virtual guests and the host operating system. A local attacker can read from the /dev/vhost-net device file and read sensitive kernel memory information.
