Recommended fix High confidence

Java SE 8u311+, Java SE 11.0.13+, Java SE 7u321+; GraalVM 20.3.4+ or 21.3+; OpenJDK packages from vendors (Fedora 36+, Debian 12+)

  1. Identify the currently installed OpenJDK/JRE version by running 'java -version'
  2. For Java SE 8: upgrade to Java SE 8u311 or later from Oracle or your JDK vendor (e.g., AdoptOpenJDK, Temurin)
  3. For Java SE 11: upgrade to Java SE 11.0.13 or later
  4. For Java SE 7: upgrade to Java SE 7u321 or later (if still under support)
  5. For GraalVM Enterprise: upgrade to 20.3.4+ or 21.3+
  6. For Fedora systems: run 'dnf update java-11-openjdk' or 'dnf update java-1.8.0-openjdk' as applicable
  7. For Debian systems: run 'apt update && apt upgrade openjdk-11-jdk' or 'apt upgrade openjdk-8-jdk' as applicable
  8. Verify the new version is active by running 'java -version'
Caveat Major version upgrades may introduce compatibility changes; test application functionality after upgrading
