When de265_push_NAL() is called with a zero-length NAL unit, the resulting NAL_unit may retain a NULL backing buffer, which is subsequently passed as the destination argument to memcpy() in NAL_unit::set_data(). Although the copy length is zero, this violates the nonnull requirement of memcpy() and results in undefined behavior, causing process termination in UBSan-instrumented builds and denial of service.","categories":["Unclassified"],"product":"n/a","vendor":"n/a","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-88373","source_modified_at":"2026-09-25T17:25:19.677Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"n/a","vendor":"n/a","versions":[{"version":"n/a","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00343,"percentile":0.26664,"score_date":"2026-10-23"},"published_at":"2026-09-24T00:00:00.000Z","modified_at":"2026-09-25T17:25:19.677Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-88373","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T17:25:19.677Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88373","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/strukturag/libde265/issues/534","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/strukturag/libde265/commit/f8d324914e43d92af23614f22959cf9eee7bf9ea"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-25T17:24:11.917709Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T17:25:19.677Z","content_hash":"e403ed6f3edbdac0a4f35beea313669efc8b9d6a10ef4538db0f78d833a24512"}}
