The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software Development Kit. This release of the Red Hat build of OpenJDK 21 (21.0.12) for portable Linux serves as a replacement for the Red Hat build of OpenJDK 21 (21.0.11) 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 TLS certificate handling (CVE-2026-46968) * JDK: Improve DTLS handshaking (CVE-2026-46917) * JDK: Enhance JPEG handling (CVE-2026-47010) * JDK: Enhance XBM image support (CVE-2026-47021) * JDK: Enhance Jar file processing (CVE-2026-47027) * JDK: Improve certification checking (CVE-2026-60147) * JDK: Enhance AWT ImagingLib (CVE-2026-47059) * JDK: Enhance Jar handling (CVE-2026-47063) * JDK: Update LCMS to 2.19 (CVE-2026-41254) Enhancement(s): * For the last couple of years, OpenJDK has used a single build shared among multiple RPMs and a tarball available on the customer portal. The single "portable" build has a release number ('p') and each RPM has its own release number ('r'). However, the RPM naming only showed the RPM release number, while the version output from the build showed the portable release number, making it unclear that they were different numbers. From this release onwards, a release field of the form 'p.r' is always used for RPMs and the version output shows 'p'. (OPENJDK-4890) Bug Fix(es): 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.

CVE-2026-46917 is a vulnerability in Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition affecting the JSSE component. It allows an unauthenticated attacker with network access via TLS to cause a partial denial of service. The vulnerability affects specific versions of Oracle Java SE and GraalVM products. The CVSS 3.1 base score is 5.3, indicating a medium severity impact focused on availability. Exploitation requires supplying data to APIs in the JSSE component without using untrusted Java Web Start applications or applets. No known exploits are reported in the wild. Oracle has not explicitly stated a patch or fix in the advisory but recommends applying Critical Patch Updates promptly.
