{"id":"RLSA-2026:9689","summary":"Important: java-21-openjdk security update","details":"The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software Development Kit.\n\nSecurity Fix(es):\n\n* JDK: Enhance crypto algorithm support (CVE-2026-22007)\n\n* JDK: Improve Kerberos credentialing (CVE-2026-22013)\n\n* JDK: Enhance Path Factories Redux (CVE-2026-22016)\n\n* JDK: Enhance Zip file reading (CVE-2026-22018)\n\n* JDK: Enhance certificate chain validation (CVE-2026-22021)\n\n* JDK: Updating FreeType 2.14.1 (CVE-2026-23865)\n\n* JDK: Enhance TLS connection handling (CVE-2026-34282)\n\n* JDK: Enhance key generation (CVE-2026-34268)\n\nBug Fix(es):\n\n* 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.
