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.","state":0,"publishedAt":"2026-10-21T08:00:32.804+00:00","modifiedAt":"2026-10-26T17:57:34.946+00:00","affected":[{"ecosystem":"Vendor product","name":"Eclipse OpenJ9","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eclipse Foundation\",\n                    \"product\": \"Eclipse OpenJ9\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.8.0\",\n                            \"lessThan\": \"0.63\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/eclipse-openj9/openj9/pull/25009","https://gitlab.eclipse.org/security/vulnerability-reports/-/work_items/941","https://gitlab.eclipse.org/security/cve-assignment/-/work_items/423"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-111075","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-111075","identifiers":["CVE-2026-111075"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
