A specially crafted EXR file containing an unknown-type attribute with dataSize set to zero causes the parser to create an opaque attribute with a NULL packed_data pointer. The OpaqueAttribute constructor passes the NULL pointer to memcpy() without validating the zero-size condition, resulting in undefined behavior and process termination, leading to denial of service."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/AcademySoftwareFoundation/openexr/issues/2612"},{"url":"https://github.com/AcademySoftwareFoundation/openexr/pull/2615"},{"url":"https://github.com/AcademySoftwareFoundation/openexr/pull/2615/changes/70ddecfe82d2566f3776b8ed923939afd47baca2"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-476","lang":"en","description":"CWE-476 NULL Pointer Dereference"}]}],"references":[{"url":"https://github.com/AcademySoftwareFoundation/openexr/issues/2612","tags":["exploit"]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.5,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-09-24T18:17:56.727213Z","id":"CVE-2026-88384","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-24T18:18:33.846Z"}}]},"dataVersion":"5.2"}
