{"cve":"CVE-2026-88914","nvd":{"published":"2026-09-11T02:18:35.300","modified":"2026-09-16T19:42:43.623","status":"Awaiting Analysis","description":"A flaw was found in GStreamer's gst-plugins-good isomp4 plugin. When processing a specially crafted MP4 or MOV file containing CEA-608 closed-caption data, an integer overflow in 32-bit unsigned arithmetic can bypass a bounds check in the caption parser. This leads to an out-of-bounds heap read of up to 244 bytes, which is then included in the downstream caption output. An attacker could exploit this by tricking a user into opening a malicious media file, potentially resulting in disclosure of adjacent heap memory or application crash.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","score":4.4},"cwes":["CWE-190"],"references":["https://access.redhat.com/security/cve/CVE-2026-88914","https://bugzilla.redhat.com/show_bug.cgi?id=2531416","https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/12433","https://gstreamer.freedesktop.org/security/sa-2026-0079.html"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-88914","score":0.00121,"percentile":0.0191,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
