It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-6881 in the wild and no public exploit code.\n\nAffected product: Zephyrproject Zephyr. 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-2023-6881/ (Markdown: https://insights.sbomify.com/CVE-2023-6881/index.md)","id":"CVE-2023-6881","markdown":"https://insights.sbomify.com/CVE-2023-6881/index.md","name":"CVE-2023-6881","record":{"aliases":["GHSA-mh67-4h3q-p437"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zephyr RTOS","requires_auth":"none","summary":"A buffer overflow in the Zephyr RTOS filesystem allows attackers to potentially execute arbitrary code or cause a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zephyr","cpe":[{"product":"zephyr","vendor":"zephyrproject"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Possible buffer overflow in is_mount_point","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"fs: fuse: buffer overflow vulnerability in the Zephyr FS","id":"CVE-2023-6881","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zephyrproject:zephyr","products":["zephyrproject:zephyr"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Simple Membership \u003c= 4.3.8 - Reflected Cross-Site Scripting Vulnerability via environment_mode","id":"CVE-2023-6882"},"packages":[],"prev":{"headline":"Visual Composer Premium \u003c= 45.6.0 - Authenticated (Contributor+) Stored Cross-Site Scripting","id":"CVE-2023-6880"},"products":["Zephyr"],"published":"2024-02-20","related":[{"cvss_score":9.8,"headline":"Out-of-bounds read/write in HTTP WebSocket upgrade via non-null-terminated Sec-WebSocket-Key","id":"CVE-2026-5067","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":9.8,"headline":"Bluetooth HCI Error Handling Double Free","id":"CVE-2022-3806","kev_date_added":null,"published":"2023-01-19"},{"cvss_score":9.8,"headline":"Memory corruption in getaddrinfo","id":"CVE-2017-14199","kev_date_added":null,"published":"2019-04-12"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2018-1000800","kev_date_added":null,"published":"2018-09-06"},{"cvss_score":9.6,"headline":"DOS: Incorrect handling of the initial HCI ACL_MTU handshake packet leads to crash of bluetooth host layer","id":"CVE-2021-3329","kev_date_added":null,"published":"2023-02-26"},{"cvss_score":9.6,"headline":"DoS: Invalid Initialization in le_read_buffer_size_complete","id":"CVE-2023-0397","kev_date_added":null,"published":"2023-01-19"},{"cvss_score":9.6,"headline":"Usb bluetooth device ACL read cb buffer overflow","id":"CVE-2021-3966","kev_date_added":null,"published":"2023-01-11"}],"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":"2024-08-02","vendors":["zephyrproject-rtos"]},"summary":"A buffer overflow in the Zephyr RTOS filesystem allows attackers to potentially execute arbitrary code or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2023-6881/"}
