How the CVE Works
CVE-2025-30752 is a vulnerability in Oracle Java SE and GraalVM for JDK (version 24.0.1) affecting the compiler component. An unauthenticated attacker exploiting this flaw via network protocols can trigger a partial denial of service (DoS) by manipulating untrusted code execution in sandboxed environments (e.g., Java Web Start/applets). The attack complexity is high (CVSS:3.1 AV:N/AC:H), requiring specific conditions where malicious code bypasses sandbox restrictions to disrupt availability (A:L). Server deployments running trusted code are unaffected.
