high Nessus Plugin ID 376976

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9 host has a package installed that is affected by a vulnerability as referenced in the CIQ crlba-2026_56986 advisory.

 The virtio-win package provides paravirtualized network drivers for most Microsoft Windows operating systems. Paravirtualized drivers are virtualization-aware drivers used by fully virtualized guests running on Rocky Linux. Fully virtualized guests using the paravirtualized drivers gain significantly better I/O performance than fully virtualized guests running without the drivers.
