It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-12892 in the wild and no public exploit code.\n\nAffected product: Gstreamer Gstreamer. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-12892/ (Markdown: https://insights.sbomify.com/CVE-2026-12892/index.md)","id":"CVE-2026-12892","markdown":"https://insights.sbomify.com/CVE-2026-12892/index.md","name":"CVE-2026-12892","record":{"aliases":["DEBIAN-CVE-2026-12892","ECHO-f069-e7ae-e4f6","GHSA-mc62-3gf7-rphg","UBUNTU-CVE-2026-12892"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GStreamer plugins","requires_auth":"none","summary":"A 1-byte heap out-of-bounds read in GStreamer's H.264 parser allows attackers to crash applications or leak memory via malicious video files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"gstreamer","vendor":"gstreamer"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur during parsing. This happens when the parser attempts to check slice boundary information without first verifying that the NAL unit contains enough data beyond the extension header. An attacker could exploit this by tricking a user into opening a malicious H.264 video file, potentially causing the application to crash or leak a single byte of heap memory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Gstreamer1-plugins-bad-free: gstreamer1-plugins-bad: 1-byte heap out-of-bounds read in h.264 nal extension slice parser","id":"CVE-2026-12892","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gstreamer:gstreamer","products":["gstreamer:gstreamer","redhat:enterprise_linux"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Code injection in Red Hat Build of Apache Camel 3.33.3.SP1","id":"CVE-2026-12894"},"packages":[],"prev":{"headline":"Information disclosure in Red Hat Enterprise Linux 10","id":"CVE-2026-12891"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9"],"published":"2026-06-23","related":[{"cvss_score":8.8,"headline":"GStreamer rtpqdm2depay Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2026-3083","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":8.8,"headline":"GStreamer rtpqdm2depay Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2026-3085","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":8.8,"headline":"GStreamer PGS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-37328","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer SRT File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-37329","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer RealMedia File Parsing Integer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-38103","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer RealMedia File Parsing Integer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-38104","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":8.8,"headline":"GStreamer MXF File Parsing Integer Overflow Remote Code Execution Vulnerability","id":"CVE-2023-40474","kev_date_added":null,"published":"2024-05-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["Red Hat"]},"summary":"A 1-byte heap out-of-bounds read in GStreamer's H.264 parser allows attackers to crash applications or leak memory via malicious video files.","url":"https://insights.sbomify.com/CVE-2026-12892/"}
