What is CVE-2021-41041?

In Eclipse OpenJ9 prior to version 0.32.0, a vulnerability exists where Java 8 and 11 do not properly handle exceptions during bytecode verification. This flaw allows for the invocation of unverified methods via MethodHandles, potentially compromising the integrity of the execution environment and leading to unintentional method executions. Proper verification mechanisms should be enforced to prevent such exploitation.
