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

Security Fix(es):

  • kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi target (CVE-2018-14633)

  • kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service (CVE-2018-14646)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank Vincent Pelletier for reporting CVE-2018-14633 and Christian Brauner for reporting CVE-2018-14646.

Bug Fix(es):

These updated kernel packages include also numerous bug fixes. Space precludes documenting all of the bug fixes in this advisory. See the descriptions in the related Knowledge Article: https://access.redhat.com/articles/3714371
