Important: java-21-openjdk security update

Published Apr 28, 2026 · Updated Apr 28, 2026

Ecosystem: Rocky Linux

Summary

The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software Development Kit.

Security Fix(es):

* JDK: Enhance crypto algorithm support (CVE-2026-22007)

* JDK: Improve Kerberos credentialing (CVE-2026-22013)

* JDK: Enhance Path Factories Redux (CVE-2026-22016)

* JDK: Enhance Zip file reading (CVE-2026-22018)

* JDK: Enhance certificate chain validation (CVE-2026-22021)

* JDK: Updating FreeType 2.14.1 (CVE-2026-23865)

* JDK: Enhance TLS connection handling (CVE-2026-34282)

* JDK: Enhance key generation (CVE-2026-34268)

Bug Fix(es):

* When copying files, OpenJDK 21 prefers to use the copy_file_range native function for performance reasons, only falling back to sendfile when this fails. However, in previous OpenJDK 21 releases, a response of EOPNOTSUPP (operation not supported) did not cause the JDK to fall back to sendfile. This is rectified in this release. (Rocky Linux-169617, Rocky Linux-169951, Rocky Linux-169952, Rocky Linux-169942, Rocky Linux-169953, Rocky Linux-169945)
