Summary
Vulnerability in Oracle Java SE (component: Libraries) allows an unauthenticated attacker with network access to cause a partial denial of service (partial DOS). The attack is easy to exploit and can be triggered via APIs, e.g., through a web service.
Risk Assessment
The risk involves potential disruption of Java applications, which may impact service availability in the organization.
Recommendation
It is recommended to update Oracle Java SE to versions 8u491, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1 or later, and corresponding GraalVM versions.

Original NVD description (English source)
Vulnerability in Oracle Java SE (component: Libraries). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and 21.0.11; Oracle GraalVM Enterprise Edition: 21.3.18. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE. 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 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
