| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2026-6918 | 8.7 high | 1.0% | eclipse, openj9 | 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. | Mon 26 Oct |
| CVE-2026-16441 | 6.9 medium | 1.0% | eclipse, openj9 | 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. | Sat 24 Oct |
| CVE-2026-111074 | 8.7 high | 0.00% | no CPE yet | In Eclipse OpenJ9 versions prior to 0.63.0, the JITServer component is vulnerable to a pre-authentication remote denial of service. When processing the initial 4-byte length field of an incoming TCP connection, an integer overflow in `MessageBuffer::computeRequiredCapacity()` causes the receiving compilation worker thread to enter an infinite loop consuming ~100% CPU. An unauthenticated remote attacker can exploit this by opening a small number of crafted TCP connections to exhaust the entire worker thread pool, silently halting compilation services for all connected client JVMs. | Mon 26 Oct |
| CVE-2026-111075 | 8.7 high | 0.00% | no CPE yet | In Eclipse OpenJ9 versions prior to 0.63.0, the JITServer component fails to perform cross-field validation on attacker-controlled `_size`, `_paddingSize`, and `_dataOffset` fields during `DataDescriptor` message deserialization. An unauthenticated remote attacker can send a crafted network payload that triggers an unsigned integer underflow in `DataDescriptor::getPayloadSize()` and `DataDescriptor::getNextDescriptor()`. This results in an out-of-bounds heap read and an immediate process crash (SIGSEGV), causing a denial of service. | Mon 26 Oct |
| CVE-2026-110938 | 8.7 high | 0.00% | no CPE yet | In Eclipse OpenJ9 versions up to 0.63.0, the JITServer component is vulnerable to denial of service due to improper boundary checks during protocol message and reply handling. An unauthenticated remote attacker or malicious JITServer can transmit malformed network payloads that cause out-of-bounds heap reads, immediately crashing the JITServer daemon or client JVM process via a segmentation fault (SIGSEGV). | Mon 26 Oct |
| CVE-2025-14549 | 6.9 medium | 0.00% | eclipse, omr | In the Eclipse OMR compiler component, since release 0.7.0, an optimization enabled for Eclipse OpenJ9 consumers of OMR on Z processors incorrectly handles NUL (0x00) characters during the Latin-compatible charset (UTF-8, ISO8859-1, ASCII, etc) to IBM-1047/037 translation sequence. This can cause the output byte array to be truncated, discarding the first NUL byte and all subsequent characters, and thereby exposing a possible buffer over-read problem. This issue is fixed in Eclipse OMR version 0.8.0. | 14 Oct |
| CVE-2026-97400 | 6.8 medium | 0.00% | no CPE yet | In Eclipse OpenJ9 versions up to 0.63, opening a supplied diagnostic dump bundle with the jdmpview tool, or equivalent DTFJ code, may cause the analyst's machine to read an arbitrary local file named inside the bundle and send its contents to an arbitrary remote host. | 20 Oct |
| CVE-2026-16439 | 5.8 medium | 0.00% | eclipse, openj9 | In Eclipse OpenJ9 versions up to 0.60, using -Xtrace to trace method arguments can lead to buffer underflow. | Sat 24 Oct |
| CVE-2026-16440 | 5.7 medium | 0.00% | no CPE yet | In Eclipse OpenJ9 versions up to 0.60, a crafted .class file with deeply nested annotations causes a segmentation fault. | 22 Oct |
