CVE-2026-88914— Gstreamer1-plugins-good: gstreamer: integer overflow and out-of-bounds read in qtdemux cea-608 closed-caption parser

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

GStreamer是GStreamer组织开源的一个多媒体处理开发框架。 GStreamer存在数字错误漏洞，该漏洞源于处理包含CEA-608字幕数据的特制MP4或MOV文件时，32位无符号算术整数溢出绕过字幕解析器边界检查，导致越界堆读取，攻击者可通过诱骗用户打开恶意媒体文件来利用，可能造成相邻堆内存泄露或应用程序崩溃。

Vulnerability Title
Gstreamer1-plugins-good: gstreamer: integer overflow and out-of-bounds read in qtdemux cea-608 closed-caption parser
Source: CVE Program / CVE List V5
Vulnerability 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.
