Memory Initialization Vulnerability in Linux Kernel vhost_new_msg() Function

CVE-2018-1118 · LOW Severity

AV:L/AC:L/AU:N/C:P/I:N/A:N

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.
