Heap-based Buffer Overflow in GStreamer Affects Remote Execution Capabilities

CVE-2026-18296

What is CVE-2026-18296?

This vulnerability in the GStreamer Multimedia Framework allows remote attackers to exploit a heap-based buffer overflow during MRF file parsing. The flaw stems from inadequate validation of user-supplied data length before it is copied to a buffer in heap memory. Successful exploitation requires the target user to either visit a malicious webpage or open a specially crafted MRF file. An attacker can leverage this flaw to execute arbitrary code within the context of the affected process, potentially compromising system integrity.
