An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-56318 exists.\n\nAffected product: Matter. 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-2024-56318/ (Markdown: https://insights.sbomify.com/CVE-2024-56318/index.md)","id":"CVE-2024-56318","markdown":"https://insights.sbomify.com/CVE-2024-56318/index.md","name":"CVE-2024-56318","record":{"aliases":["GHSA-93xr-jvr5-8x88"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Matter IoT framework","requires_auth":"none","summary":"Attackers can cause denial of service in Matter devices by sending TCP packets with zero message size, triggering a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In raw\\TCP.cpp in Matter (aka connectedhomeip or Project CHIP) through 1.4.0.0 before 27ca6ec, there is a NULL pointer dereference in TCPBase::ProcessSingleMessage via TCP packets with zero messageSize, leading to denial of service.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Null dereference in Matter","id":"CVE-2024-56318","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in Matter","id":"CVE-2024-56319"},"packages":[],"prev":{"headline":"Denial of service in Matter","id":"CVE-2024-56317"},"products":["Matter"],"published":"2024-12-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-02","vendors":["Matter"]},"summary":"Attackers can cause denial of service in Matter devices by sending TCP packets with zero message size, triggering a null pointer dereference.","url":"https://insights.sbomify.com/CVE-2024-56318/"}
