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. (AlmaLinux-13930, AlmaLinux-13931, AlmaLinux-13934, AlmaLinux-13935)
