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-2026-103672/ (Markdown: https://insights.sbomify.com/CVE-2026-103672/index.md)","id":"CVE-2026-103672","markdown":"https://insights.sbomify.com/CVE-2026-103672/index.md","name":"CVE-2026-103672","record":{"aliases":["GHSA-6q94-5hqp-c754"],"analysis":null,"analysis_generated_by":null,"assigner":"icscert","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"The PEAK-System PCAN parser indexes a length table using attacker-controlled DLC without enforcing DLC \u003c= 0x0f, then copies attacker payload from record+0x1c into a fixed-size stack destination.","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":"HMS Networks PEAK-System PCAN Windows drivers Improper Validation of Array Index","id":"CVE-2026-103672","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Tnef: heap out-of-bounds read in get_rtf_data_from_buf() via uncompressed rtf mapi value","id":"CVE-2026-103678"},"packages":[],"prev":{"headline":"Open redirect in AmazonPay Plugin (4.0 series)","id":"CVE-2026-103671"},"products":["PCAN Windows CAN device drivers","PEAK-System Device Driver Setup"],"published":"2026-10-20","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-20","vendors":["HMS Networks"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-103672/"}
