| Impact | Despite the high CVSS score of 9.1, the real-world exploitation risk appears moderate based on multiple factors. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H) indicates network-exploitable with no authentication required and low complexity, which is concerning. However, the vulnerability is not listed in CISA's KEV catalog, suggesting no known active exploitation. The attack requires processing a specially crafted WAV file, limiting the attack surface to applications that accept user-supplied media files. The primary impact is denial of service through crashes, though memory disclosure is theoretically possible. The availability of patches and public security advisories since the disclosure reduces the window for exploitation. |
| Exploit ScenarioDerived | An attacker could host a malicious WAV file on a website or send it via email attachment to target media processing applications. When the victim's GStreamer-based application attempts to parse the specially crafted WAV file with malformed CUE chunk data, it triggers the out-of-bounds read, causing the application to crash or potentially exposing sensitive memory contents. Given the low attack complexity and network attack vector, automated scanning for vulnerable services processing media files is feasible. |

Alert meAnalysisAIv1 – Mar 17, 2026
An out-of-bounds read vulnerability exists in GStreamer's WAV file parser that allows remote attackers to crash applications or potentially leak sensitive memory contents when processing maliciously crafted WAV files. The vulnerability affects all GStreamer versions prior to 1.24.10 and can be triggered without authentication through network-accessible media processing applications. While no active exploitation has been observed in the wild (not in KEV), the vulnerability has a high CVSS score of 9.1 and detailed technical analysis is publicly available.
RemediationAI
Upgrade GStreamer to version 1.24.10 or later, which contains the official patch available at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8042.patch. System administrators should prioritize updating media processing servers and applications that handle untrusted WAV files from external sources. As a temporary mitigation until patching is complete, consider implementing input validation to reject or sanitize WAV files before processing, or isolating media processing services in sandboxed environments to limit the impact of potential crashes or memory disclosure.

Technical ContextAI · show details
GStreamer is a widely-used open-source multimedia framework for constructing media processing pipelines, identified by CPE cpe:2.3:a:gstreamer:gstreamer:*:*:*:*:*:*:*:*. The vulnerability occurs in the gst_wavparse_cue_chunk function within gstwavparse.c, where a size calculation error allows reading beyond allocated buffer boundaries when parsing CUE chunks in WAV files. This is a classic CWE-125 out-of-bounds read vulnerability caused by improper validation of chunk sizes against available buffer data, specifically when the comparison 'if (size < 4 + ncues * 24)' fails due to upstream data size miscalculation during chunk clipping operations.

Lifecycle Timeline
2DescriptionGitHub Advisory
GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been discovered in gst_wavparse_cue_chunk within gstwavparse.c. The vulnerability happens due to a discrepancy between the size of the data buffer and the size value provided to the function. This mismatch causes the comparison if (size < 4 + ncues * 24) to fail in some cases, allowing the subsequent loop to access beyond the bounds of the data buffer. The root cause of this discrepancy stems from a miscalculation when clipping the chunk size based on upstream data size. This vulnerability allows reading beyond the bounds of the data buffer, potentially leading to a crash (denial of service) or the leak of sensitive data. This vulnerability is fixed in 1.24.10.
Executive ViewAI
Organizations using GStreamer face critical risk from CVE-2024-47776, a out-of-bounds read vulnerability rated CVSS 9.1. Successful exploitation could critically impact the confidentiality, integrity, and availability of affected systems. A patch is available and should be applied immediately given the critical severity.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
