The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3309 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * kernel: nfs: use-after-free in svc_process_common() (CVE-2018-16884)

    * Kernel: vhost_net: infinite loop while receiving packets leads to DoS (CVE-2019-3900)
