Detailed Description The remote system does not apply CESA-2019:2829 which is kernel security update. The system which does not apply the update is affected by a buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.

Note: This check solely relied on the kernel RPM version of the remote system to assess this vulnerability, so this might be a false positive.
