The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3010 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * kernel: use-after-free in sound/core/timer.c (CVE-2019-19807)

    * kernel: kernel: DAX hugepages not considered during mremap (CVE-2020-10757)

    * kernel: Indirect Branch Prediction Barrier is force-disabled when STIBP is unavailable or enhanced IBRS     is available. (CVE-2020-10767)

    * kernel: Indirect branch speculation can be enabled after it was force-disabled by the     PR_SPEC_FORCE_DISABLE prctl command. (CVE-2020-10768)

    * kernel: buffer overflow in mwifiex_cmd_append_vsie_tlv function in     drivers/net/wireless/marvell/mwifiex/scan.c (CVE-2020-12653)

    * kernel: heap-based buffer overflow in mwifiex_ret_wmm_get_status function in     drivers/net/wireless/marvell/mwifiex/wmm.c (CVE-2020-12654)

    * Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario (CVE-2020-12888)

    * kernel: kvm: Information leak within a KVM guest (CVE-2019-3016)
