    1. Summary:
    
    An update for kernel is now available for Red Hat Enterprise Linux 7.5
    Extended Update Support.
    
    Red Hat Product Security has rated this update as having a security impact
    of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
    gives a detailed severity rating, is available for each vulnerability from
    the CVE link(s) in the References section.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux ComputeNode EUS (v. 7.5) - noarch, x86_64
    Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.5) - x86_64
    Red Hat Enterprise Linux Server EUS (v. 7.5) - noarch, ppc64, ppc64le, s390x, x86_64
    Red Hat Enterprise Linux Server Optional EUS (v. 7.5) - ppc64, ppc64le, x86_64
    
    3. Description:
    
    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.
    
    Security Fix(es):
    
    * kernel: Use-after-free in snd_pcm_info function in ALSA subsystem
    potentially leads to privilege escalation (CVE-2017-0861)
    
    * 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):
    
    * Hard lockup in free_one_page()->_raw_spin_lock() because sosreport
    command is reading from /proc/pagetypeinfo (BZ#1770730)
