CVE-2024-0340: Kernel: information disclosure in vhost/vhost.c:vhost_new_msg()

First published: Tue Jan 09 2024(Updated: )

A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which 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 issue can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
