CVE-2026-34282
Full vulnerability record from the local CVENow database.
Description
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Networking). Supported versions that are affected are Oracle Java SE: 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. Easily exploitable 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 hang or frequently repeatable crash (complete 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. 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 7.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

Los ataques exitosos de esta vulnerabilidad pueden resultar en la capacidad no autorizada de causar un bloqueo o una caída (crash) frecuentemente repetible (DoS completo) de Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Nota: Esta vulnerabilidad puede ser explotada utilizando APIs en el Componente especificado, por ejemplo, a través de un servicio web que suministra datos a las APIs. Esta vulnerabilidad también se aplica a las implementaciones de Java, típicamente en clientes que ejecutan aplicaciones Java Web Start en sandbox o applets Java en sandbox, que cargan y ejecutan código no confiable (por ejemplo, código que proviene de internet) y dependen del sandbox de Java para la seguridad.
