Red Hat Product Security has rated this update as having a security impact of Important.

Description The OpenJDK 25 packages provide the OpenJDK 25 Java Runtime Environment and the OpenJDK 25 Java Software Development Kit. This release of the Red Hat build of OpenJDK 25 (25.0.3) for portable Linux serves as a replacement for the Red Hat build of OpenJDK 25 (25.0.2) and includes security and bug fixes as well as enhancements. For further information, refer to the release notes linked to in the References section. Security Fix(es): JDK: Enhance crypto algorithm support (CVE-2026-22007) JDK: Improved Arena allocations (CVE-2026-22008) 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 25 prefers to use the copy_file_range native function for performance reasons, only falling back to sendfile when this fails. However, in previous OpenJDK 25 releases, a response of EOPNOTSUPP (operation not supported) did not cause the JDK to fall back to sendfile. This is rectified in this release.
