{"schema":"threatline.record/2","record":{"id":"CVE-2026-100229","aliases":[],"summary":"Gstreamer1-plugins-bad-free: gstreamer1-plugins-bad-free: out-of-bounds write in gst_h266_parser_parse_dci() due to off-by-one array bound check","details":"A flaw was found in GStreamer's H.266 codec parser library (libgstcodecparsers). An out-of-bounds write vulnerability exists in the DCI parsing function, where a reserved field value is incorrectly accepted, causing the parser to write beyond the bounds of an internal structure. An attacker could exploit this by providing a specially crafted H.266 bitstream to a third-party application that uses this library API, potentially causing a crash or memory corruption. No standard GStreamer pipeline element currently invokes the affected code path.","categories":["Operating systems"],"product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100229","source_modified_at":"2026-10-14T14:11:54.060Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100229","source_modified_at":"2026-10-14T14:11:54.060Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100229","source_modified_at":"2026-10-14T14:11:54.060Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100229","source_modified_at":"2026-10-14T14:11:54.060Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00364,"percentile":0.29115,"score_date":"2026-10-23"},"published_at":"2026-10-14T10:02:12.688Z","modified_at":"2026-10-14T14:11:54.060Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100229","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T14:11:54.060Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100229","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-100229","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2541471","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-14T14:11:42.472789Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-14T14:11:54.060Z","content_hash":"53c0ae37dc2224d01c2213b4c3a51daf8e3a6b7801f02a1451815e228ccd3989"}}
