RockyLinux 9 : java-21-openjdk (RLSA-2026:9689)

high Nessus Plugin ID 310569

Synopsis

The remote RockyLinux host is missing one or more security updates.

Description

The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:9689 advisory.

* 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)

Tenable has extracted the preceding description block directly from the RockyLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
