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."], "mitigation": {"lang": "en:us", "value": "No mitigation is currently available that meets Red Hat Product Security's standards for usability, deployment, applicability, or stability."}, "name": "CVE-2026-88914", "public_date": "2026-09-10T14:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-88914\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-88914\nhttps://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/12433\nhttps://gstreamer.freedesktop.org/security/sa-2026-0079.html"], "statement": "This vulnerability is rated as Moderate because exploitation requires a user to open a crafted MP4 or MOV file and the issue is limited to an out-of-bounds read of up to approximately 244 bytes of adjacent heap memory.
