MITRE ATT&CK
1 technique across 1 tactic: Impact The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | The CVSS 3.1 score of 7.5 (High) reflects a network-exploitable vulnerability requiring no authentication or user interaction (AV:N/AC:L/PR:N/UI:N), but only impacts availability (A:H) with no confidentiality or integrity impact. The low EPSS score of 0.11% (30th percentile) suggests minimal active exploitation in the wild, and the vulnerability is not listed in CISA's KEV catalog. While the technical impact is limited to denial of service, the ease of exploitation (low complexity, no privileges required) and the widespread use of GStreamer in media applications make this a medium-priority issue for organizations processing untrusted media files. |
| Exploit ScenarioDerived | An attacker could craft a malicious Matroska (MKV) or WebM file with specially crafted capability values and serve it through a web application or send it via email. When a vulnerable GStreamer-based application attempts to process the file, the null pointer dereference would cause the application to crash, resulting in a denial of service. Given the network attack vector and low complexity, this could be easily automated to target media streaming services or content management systems. |

Alert meAnalysisAIv1 – Mar 17, 2026
A null pointer dereference vulnerability exists in GStreamer's Matroska demuxer that allows remote attackers to cause a denial of service crash. The flaw occurs when processing malformed Matroska media files with invalid capability values, leading to a null pointer dereference in the gst_matroska_demux_update_tracks function. With an EPSS score of 0.11% and no known active exploitation, this represents a moderate real-world risk primarily affecting media processing applications.
RemediationAI
Upgrade GStreamer to version 1.24.10 or later, which contains the fix for this vulnerability as detailed in the patch at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8057.patch. Organizations unable to immediately patch should implement input validation for media files and consider running media processing services in isolated environments with resource limits to minimize the impact of potential crashes. Additional details are available in the GitHub Security Lab advisory at https://securitylab.github.com/advisories/GHSL-2024-251_Gstreamer/.

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 manifests as a CWE-476 (NULL Pointer Dereference) in the Matroska demuxer component, specifically within matroska-demux.c. When the gst_caps_is_equal function receives invalid capability values during track updates, it causes GST_BUFFER_MEM_PTR to return null, which is then dereferenced when accessing the size field, causing an application crash.

Lifecycle Timeline
2DescriptionGitHub Advisory
GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_update_tracks function within matroska-demux.c. The vulnerability occurs when the gst_caps_is_equal function is called with invalid caps values. If this happen, then in the function gst_buffer_get_size the call to GST_BUFFER_MEM_PTR can return a null pointer. Attempting to dereference the size field of this null pointer results in a null pointer dereference. This vulnerability is fixed in 1.24.10.
Executive ViewAI
Organizations using GStreamer face notable risk from CVE-2024-47603, a null pointer dereference vulnerability rated CVSS 7.5. Exploitation could compromise the security of affected deployments. A patch is available and should be applied as part of regular vulnerability management.
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.
