Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-2026_42899 advisory.

* 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'. (Rocky Linux-211046, Rocky Linux-211048)

Bug Fix(es):

* The performance of the Math.pow function regressed between OpenJDK 8 and OpenJDK 11. This was due to an absence of constant folding when applicable (for example, Math.pow(2,1) being replaced by 2). This release reintroduces this optimization. (Rocky Linux-211050, Rocky Linux-211052)
* On Rocky Linux 9 systems, the alternatives list a JDK and architecture pair (for example, java-11-openjdk.x86_64) followed by the path to the binary in brackets. Rocky Linux 10 systems have a simpler format that just lists the path. Because the OpenJDK 25 packages for Rocky Linux 9 were originally based on those from Rocky Linux 10, they used the simpler format. With this release, the format for OpenJDK 25 packages on Rocky Linux 9 is updated to be closer to other JDKs on that platform.
