    * kernel: Use-after-free vulnerability in DCCP socket (CVE-2017-8824, Important)

    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 Mohamed Ghannam for reporting this issue.

    Bug Fix(es):

    * Previously, the XFS code included a circular dependency between the xfs-log and the xfs-cil workqueues.
    Consequently, an XFS deadlock occurred in some cases. This update adds a new workqueue dedicated to the     log covering background task to avoid the deadlock. (BZ#1543303)

    * The kernel build requirements have been updated to the GNU Compiler Collection (GCC) compiler version     that has the support for Retpolines. The Retpolines mechanism is a software construct that leverages     specific knowledge of the underlying hardware to mitigate the branch target injection, also known as     Spectre variant 2 vulnerability described in CVE-2017-5715. (BZ#1553181)
