RHSA-2018:1350: Moderate: kernel security and bug fix update
First published: Tue May 08 2018(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux operating system.<br>Security Fix(es):<br><li> Kernel: error in exception handling leads to DoS (CVE-2018-8897)</li> 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.<br>Red Hat would like to thank Nick Peterson (Everdox Tech LLC) and Andy Lutomirski for reporting this issue.<br>Bug Fix(es):<br><li> 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#1554256)</li>
