CVE Severity Published▾ Status Exploitation Description
CVE-2026-16441 Medium 2026-07-21 No exploit published No public exploit In Eclipse OpenJ9 versions up to 0.60, when executing class files where a previously concrete superclass method has been recompiled as abstract, execution is incorrectly delegated to an interface default method.
CVE-2026-16439 Medium 2026-07-21 No exploit published No public exploit In Eclipse OpenJ9 versions up to 0.60, using -Xtrace to trace method arguments can lead to buffer underflow.
CVE-2026-6918 High 2026-05-05 No exploit published Proof of concept only In Eclipse Open9J versions 0.21 to 0.58, a pre-authentication remote attacker can crash JITServer by sending a 32-byte crafted TCP message.
CVE-2025-4447 High 2025-05-09 No exploit published No public exploit In Eclipse OpenJ9 versions up to 0.51, when used with OpenJDK version 8 a stack based buffer overflow can be caused by modifying a file on disk that is read when the JVM starts.
CVE-2024-10917 Medium 2024-11-11 No exploit published No public exploit In Eclipse OpenJ9 versions up to 0.47, the JNI function GetStringUTFLength may return an incorrect value which has wrapped around. From 0.48 the value is correct but may be truncated to include a smaller number of characters.
CVE-2024-3933 High 2024-05-27 No exploit published No public exploit In Eclipse OpenJ9 release versions prior to 0.44.0 and after 0.13.0, when running with JVM option -Xgc:concurrentScavenge, the sequence generated for System.arrayCopy on the IBM Z platform with hardware and software support for guarded storage [1], could allow access to a buffer with an incorrect length value when executing an arraycopy sequence while the Concurrent Scavenge Garbage Collection cycle is active and the source and destination memory regions for arraycopy overlap. This allows read and write to addresses beyond the end of the array range.
CVE-2023-5676 Medium 2023-11-15 No exploit published No public exploit In Eclipse OpenJ9 before version 0.41.0, the JVM can be forced into an infinite busy hang on a spinlock or a segmentation fault if a shutdown signal (SIGTERM, SIGINT or SIGHUP) is received before the JVM has finished initializing.
CVE-2023-2597 Critical 2023-05-22 No exploit published No public exploit In Eclipse Openj9 before version 0.38.0, in the implementation of the shared cache (which is enabled by default in OpenJ9 builds) the size of a string is not properly checked against the size of the buffer.
CVE-2022-3676 Medium 2022-10-24 No exploit published No public exploit In Eclipse Openj9 before version 0.35.0, interface calls can be inlined without a runtime type check. Malicious bytecode could make use of this inlining to access or modify memory via an incompatible type.
CVE-2021-41041 Medium 2022-04-27 No exploit published No public exploit In Eclipse Openj9 before version 0.32.0, Java 8 & 11 fail to throw the exception captured during bytecode verification when verification is triggered by a MethodHandle invocation, allowing unverified methods to be invoked using MethodHandles.
CVE-2021-41035 Critical 2021-10-25 No exploit published No public exploit In Eclipse Openj9 before version 0.29.0, the JVM does not throw IllegalAccessError for MethodHandles that invoke inaccessible interface methods.
CVE-2021-28167 Medium 2021-04-21 Outside Waratek scope Proof of concept only In Eclipse Openj9 to version 0.25.0, usage of the jdk.internal.reflect.ConstantPool API causes the JVM in some cases to pre-resolve certain constant pool entries. This allows a user to call static methods or access static members without running the class initialization method, and may allow a user to observe uninitialized values.
CVE-2020-27221 Critical 2021-01-21 Outside Waratek scope No public exploit In Eclipse OpenJ9 up to and including version 0.23, there is potential for a stack-based buffer overflow when the virtual machine or JNI natives are converting from UTF-8 characters to platform encoding.
CVE-2019-17639 Medium 2020-07-15 No exploit published No public exploit In Eclipse OpenJ9 prior to version 0.21 on Power platforms, calling the System.arraycopy method with a length longer than the length of the source or destination array can, in certain specially crafted code patterns, cause the current method to return prematurely with an undefined return value. This allows whatever value happens to be in the return register at that time to be used as if it matches the method's declared return type.
CVE-2019-17631 Critical 2019-10-17 No exploit published No public exploit From Eclipse OpenJ9 0.15 to 0.16, access to diagnostic operations such as causing a GC or creating a diagnostic file are permitted without any privilege checks.
CVE-2019-11775 High 2019-07-30 No exploit published No public exploit All builds of Eclipse OpenJ9 prior to 0.15 contain a bug where the loop versioner may fail to privatize a value that is pulled out of the loop by versioning - for example if there is a condition that is moved out of the loop that reads a field we may not privatize the value of that field in the modified copy of the loop allowing the test to see one value of the field and subsequently the loop to see a modified field value without retesting the condition moved out of the loop. This can lead to a variety of different issues but read out of array bounds is one major consequence of these problems.
CVE-2019-11772 Critical 2019-07-17 No exploit published No public exploit In Eclipse OpenJ9 prior to 0.15, the String.getBytes(int, int, byte[], int) method does not verify that the provided byte array is non-null nor that the provided index is in bounds when compiled by the JIT. This allows arbitrary writes to any 32-bit address or beyond the end of a byte array within Java code run under a SecurityManager.
CVE-2019-11771 High 2019-07-17 No exploit published No public exploit AIX builds of Eclipse OpenJ9 before 0.15.0 contain unused RPATHs which may facilitate code injection and privilege elevation by local users.
CVE-2019-10245 High 2019-04-19 No exploit published No public exploit In Eclipse OpenJ9 prior to the 0.14.0 release, the Java bytecode verifier incorrectly allows a method to execute past the end of bytecode array causing crashes. Eclipse OpenJ9 v0.14.0 correctly detects this case and rejects the attempted class load.
CVE-2018-12549 Critical 2019-02-11 No exploit published No public exploit In Eclipse OpenJ9 version 0.11.0, the OpenJ9 JIT compiler may incorrectly omit a null check on the receiver object of an Unsafe call when accelerating it.
CVE-2018-12547 Critical 2019-02-11 No exploit published No public exploit In Eclipse OpenJ9, prior to the 0.12.0 release, the jio_snprintf() and jio_vsnprintf() native methods ignored the length parameter. This affects existing APIs that called the functions to exceed the allocated buffer. This functions were not directly callable by non-native user code.
CVE-2018-12548 Critical 2019-01-31 No exploit published No public exploit In OpenJDK + Eclipse OpenJ9 version 0.11.0 builds, the public jdk.crypto.jniprovider.NativeCrypto class contains public static natives which accept pointer values that are dereferenced in the native code.
CVE-2018-12539 High 2018-08-14 Protected by Waratek No public exploit In Eclipse OpenJ9 version 0.8, users other than the process owner may be able to use Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations, which includes the ability to execute untrusted native code. Attach API is enabled by default on Windows, Linux and AIX JVMs and can be disabled using the command line option -Dcom.ibm.tools.attach.enable=no.
