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.","epss":{"date":"2026-11-05","percentile":0.01942,"score":0.00121},"exploits":[],"kev":null,"metrics":[{"score":4.4,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","version":"3.1"}],"modifiedAt":1793927614870,"publishedAt":1789091323886,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-88914"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2531416"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/12433"},{"source":"CNA: redhat","tags":[],"url":"https://gstreamer.freedesktop.org/security/sa-2026-0079.html"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"No mitigation is currently available that meets Red Hat Product Security's standards for usability, deployment, applicability, or stability."}],"revision":"ee4b981bee1c5ace1d6878c4c5028843e610ab31c3bfe5e9f1f9bc47cca3c30c","sources":[{"modifiedAt":1793927614870,"name":"CNA: redhat","retrievedAt":1793931054318,"url":"https://www.cve.org/CVERecord?id=CVE-2026-88914"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793931089718,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88914"}],"ssvc":{"assessedAt":1789136137604,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Gstreamer1-plugins-good: gstreamer: integer overflow and out-of-bounds read in qtdemux cea-608 closed-caption parser","updatedAt":1793931089718}
