RHBA-2017:1719 - Bug Fix Advisory

Topic

Updated kernel packages that fix one bug are now available for Red Hat
Enterprise Linux 6.6 Advanced Update Support.

Description

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

This update fixes the following bug:

When upgrading to kernel with the fix for stack guard flaw, a crash could occur in Java Virtual Machine (JVM) environments, which attempted to implement their own stack guard page. With this update, the underlying source code has been fixed to consider the PROT_NONE mapping as a part of the stack, and the crash in JVM no longer occurs under the described circumstances. (BZ#1466820)

Users of kernel are advised to upgrade to these updated packages, which fix this bug. The system must be rebooted for this update to take effect.
