Description
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.
Weaknesses (CWE)
- CWE-665 — Improper Initialization
- CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor
