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

Security Fix(es):

  • kernel: Use-after-free due to race condition in AF_PACKET implementation (CVE-2018-18559)

  • kernel: userfaultfd bypasses tmpfs file permissions (CVE-2018-18397)

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.

Bug Fix(es):

These updated kernel packages include also numerous bug fixes and 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/3827321
