The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0036 advisory.The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):

* kernel: Handling of might_cancel queueing is not properly pretected against race (CVE-2017-10661)
* kernel: kvm: guest userspace to guest kernel write (CVE-2018-10853)
* kernel: TLB flush happens too late on mremap (CVE-2018-18281)
* kernel: a NULL pointer dereference in drivers/scsi/megaraid/megaraid_sas_base.c leading to DoS (CVE-2019-11810)
* kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c (CVE-2019-11811)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
