openjdk: OpenJDK: Improve Nashorn index handling (Oracle CPU 2026-07)

Published Jul 21, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
Vulnerability in Oracle Java SE (component: Scripting). Supported versions that are affected are Oracle Java SE: 8u491, 8u491-perf and 11.0.31. 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 hang or frequently repeatable crash (complete 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 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).
