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-2026-4017 in the wild and no public exploit code.\n\nAffected product: BlackBerry Ltd QNX OS for Medical. 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-2026-4017/ (Markdown: https://insights.sbomify.com/CVE-2026-4017/index.md)","id":"CVE-2026-4017","markdown":"https://insights.sbomify.com/CVE-2026-4017/index.md","name":"CVE-2026-4017","record":{"aliases":["GHSA-8422-84vm-vcr2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QNX Neutrino kernel","requires_auth":"none","summary":"A local attacker can exploit a buffer overflow in the QNX kernel to disclose information, tamper with data, or crash the system.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"blackberry","cpe":[],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Buffer Overflow in the entry handler of the TraceEvent() system call could allow an attacker with local access to cause information disclosure, data tampering or a crash of the QNX Neutrino kernel.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in QNX OS for Medical","id":"CVE-2026-4017","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Race condition in QNX OS for Medical","id":"CVE-2026-4018"},"packages":[],"prev":{"headline":"GPAC SVG Parser load_svg.c svgin_process out-of-bounds write","id":"CVE-2026-4016"},"products":["QNX OS for Medical","QNX OS for Safety","QNX Software Development Platform"],"published":"2026-07-14","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-14","vendors":["BlackBerry Ltd","BlackBerry Ltd."]},"summary":"A local attacker can exploit a buffer overflow in the QNX kernel to disclose information, tamper with data, or crash the system.","url":"https://insights.sbomify.com/CVE-2026-4017/"}
