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

Bug Fix(es):

* When Transparent Huge Pages (THP) are unconditionally enabled on a system, Java applications using many threads were found to have a large Resident Set Size (RSS). This was due to a race between the kernel transforming thread stack memory into huge pages and the Java Virtual Machine (JVM) shattering these pages into smaller ones when adding a guard page. This release resolves this issue by getting glibc to insert a guard page and prevent the creation of huge pages. (RHEL-13930, RHEL-13931, RHEL-13934, RHEL-13935)
