Red Hat Security Advisory: OpenJDK 25.0.3 Security Update for Portable Linux Builds
Severity
Important
Notes
Topic: An update is now available for OpenJDK.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The OpenJDK 25 packages provide the OpenJDK 25 Java Runtime Environment and the OpenJDK 25 Java Software Development Kit.
This release of the Red Hat build of OpenJDK 25 (25.0.3) for portable Linux serves as a replacement for the Red Hat build of OpenJDK 25 (25.0.2) 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 crypto algorithm support (CVE-2026-22007)
* JDK: Improved Arena allocations (CVE-2026-22008)
* 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 25 prefers to use the copy_file_range native function for performance reasons, only falling back to sendfile when this fails. However, in previous OpenJDK 25 releases, a response of EOPNOTSUPP (operation not supported) did not cause the JDK to fall back to sendfile. This is rectified in this release. (OPENJDK-4675)
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.

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Security). Supported versions that are affected are Oracle Java SE: 8u481, 8u481-b50, 8u481-perf, 11.0.30, 17.0.18, 21.0.10, 25.0.2, 26; Oracle GraalVM for JDK: 17.0.18 and 21.0.10; Oracle GraalVM Enterprise Edition: 21.3.17. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition executes to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 2.9 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).

Vulnerability in Oracle Java SE (component: Libraries). The supported version that is affected is Oracle Java SE: 25.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).
CWE-122 - Heap-based Buffer OverflowAffected products
Fixed
1 product, the same list as for
CVE-2026-22007
Threats
Impact
Low
A flaw was found in OpenJDK. Because initial authentication challenges are transmitted in cleartext, a remote attacker intercepting network traffic can modify the iteration count during Kerberos authentication. This manipulation can enable key recovery, leading to sensitive information disclosure, or cause client authentication tools such as kinit to execute for an extended duration, resulting in a Denial of Service (DoS).

Threats
Impact
Moderate
A flaw was found in openjdk. When compiling XPath expressions, the internal XML security manager is not properly initialized, failing to restrict external entity resolution. A remote attacker could exploit this vulnerability by supplying specially crafted XML input to trigger XML External Entity (XXE) injection or XML Entity Expansion (XEE). Successful exploitation primarily leads to unauthorized information disclosure, such as the exposure of sensitive local files, and can also cause a Denial of Service (DoS) through resource exhaustion.

Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs.

Fixed
1 product, the same list as for
CVE-2026-22007
Threats
Impact
Low
A flaw was found in OpenJDK. A remote attacker can cause a Denial of Service (DoS) by inducing excessive processor utilization. When communicating over a Transport Layer Security (TLS) connection, if a remote server sends a connection closure notification but subsequently transmits additional data over the same connection before closing it, the receiving thread enters an infinite processing loop. This behavior causes the affected thread to consume 100% CPU, disrupting application performance and service availability.

When communicating over a Transport Layer Security (TLS) connection, if a remote server sends a connection closure notification but subsequently transmits additional data over the same connection before closing it, the receiving thread enters an infinite processing loop. This behavior causes the affected thread to consume 100% CPU, disrupting application performance and service availability.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
