RHEL 10 / 8 / 9 : java-21-openjdk (RHSA-2025:10873)

high Nessus Plugin ID 242209

Synopsis

The remote Red Hat host is missing one or more security updates for java-21-openjdk.

Description

The remote Redhat Enterprise Linux 10 / 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:10873 advisory.

The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software Development Kit.

Security Fix(es):

* JDK: Better Glyph drawing (CVE-2025-30749)
* JDK: Enhance TLS protocol support (CVE-2025-30754)
* JDK: Improve HTTP client header handling (CVE-2025-50059)
* JDK: Better Glyph drawing redux (CVE-2025-50106)

Bug Fix(es):

* In Red Hat Enterprise Linux 9 and Red Hat Enterprise Linux 10 systems, the default graphical display system is Wayland. The use of Wayland in these systems causes a failure in the traditional X11 method that java.awt.Robot uses to take a screen capture, producing a blank image. With this update, the RPM now recommends installing the PipeWire package, which the JDK can use to take screen captures in Wayland systems (RHEL-102683, RHEL-102684, RHEL-102685)
* On NUMA systems, the operating system can choose to migrate a task from one NUMA node to another. In the G1 garbage collector, G1AllocRegion objects are associated with NUMA nodes. The G1Allocator code assumes that obtaining the G1AllocRegion object for the current thread is sufficient, but OS scheduling can lead to arbitrary changes in the NUMA-to-thread association. This can cause crashes when the G1AllocRegion being used changes mid-operation. This update resolves this issue by always using the same NUMA node and associated G1AllocRegion object throughout an operation. (RHEL-90307, RHEL-90308, RHEL-90311)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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

Update the RHEL java-21-openjdk package based on the guidance in RHSA-2025:10873.
