The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4609 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: use after free due to race condition in the video driver leads to local privilege escalation     (CVE-2019-9458)

    * kernel: use-after-free in drivers/bluetooth/hci_ldisc.c (CVE-2019-15917)
