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

Security Fix(es):

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

  • kernel: insufficient input validation in kernel mode driver in Intel i915 graphics leads to privilege escalation (CVE-2019-11085)

  • kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence (CVE-2018-16871)

  • 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) and Enhancement(s):

These updated kernel packages include also numerous bug fixes and add several enhancements. Space precludes documenting all of the bug fixes in this advisory. See the descriptions in the related Knowledge Article: https://access.redhat.com/articles/4309211
