Name of the Vulnerable Software and Affected Versions OpenJDK + Eclipse OpenJ9 version 0.11.0

Description The issue concerns the public jdk.crypto.jniprovider.NativeCrypto class in OpenJDK + Eclipse OpenJ9, which contains public static natives that accept pointer values. These pointer values are dereferenced in the native code, potentially leading to issues.
