CVE-2024-0340
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.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
