{"identifier":"CVE-2026-100229","cve":{"id":"CVE-2026-100229","description":"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.","published":"2026-10-14T11:16:56.620000+00:00","modified":"2026-10-15T16:33:26.290000+00:00","status":"Awaiting Analysis","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","cvss_version":"3.1","affected":[],"weaknesses":["CWE-787"],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-100229","source":"secalert@redhat.com"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2541471","source":"secalert@redhat.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":2.5}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-14T14:11:42.472789Z","id":"CVE-2026-100229","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:22:08.367800+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00296,"percentile":0.22236,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"access.redhat.com","source_url":"https://access.redhat.com/security/cve/CVE-2026-100229","investigate_url":"https://investigate.aeglixmind.com/#access.redhat.com"},{"domain":"bugzilla.redhat.com","source_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2541471","investigate_url":"https://investigate.aeglixmind.com/#bugzilla.redhat.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-100229","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-100229","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-100229","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
