DescriptionCVE.org

Vulnerability in Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 7u511. 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 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L).

AnalysisAI

Denial-of-service and minor integrity impact in Oracle Java SE 7u511 allows unauthenticated remote attackers to crash or hang the JVM via the 2D graphics rendering component, exploitable across multiple network protocols with no authentication or user interaction required. The attack surface is broadened by the component's exposure through APIs consumed by web services, sandboxed Java Web Start applications, and sandboxed Java applets loading untrusted code. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target system is running Oracle Java SE 7u511 specifically. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 6.5 is derived from a medium availability and integrity impact combination (A:L/I:L) rather than a full availability-only score, yet the advisory text describes the outcome as a 'complete DOS' and 'hang or frequently repeatable crash' - language that typically aligns with A:H. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary remediation is to apply Oracle's Critical Patch Update containing the fix for CVE-2026-71054; the advisory is available at https://support.oracle.com/support/?documentId=CPU330 for Oracle support subscribers. … Detailed patch versions, workarounds, and compensating controls in full report.
