What is CVE-2026-17072?

A vulnerability exists in GStreamer's gst-plugins-good where a heap-based out-of-bounds read of 4 bytes can occur when parsing FLAC audio stream headers in a Matroska or WebM container file. Due to insufficient boundary checks, the flaw allows for a read operation that may lead to the disclosure of adjacent heap memory. This vulnerability can be exploited by an attacker through a specially crafted Matroska or WebM file, prompting users to open it and thereby potentially exposing sensitive data.
