Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-80146 in the wild and no public exploit code.\n\nAffected product: LANTRONIX EMG7500. 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-2026-80146/ (Markdown: https://insights.sbomify.com/CVE-2026-80146/index.md)","id":"CVE-2026-80146","markdown":"https://insights.sbomify.com/CVE-2026-80146/index.md","name":"CVE-2026-80146","record":{"aliases":["GHSA-88xg-5qpc-c627"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Lantronix out-of-band devices","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary code on Lantronix out-of-band devices via a stack-based buffer overflow in the mfc eeprom read command.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Lantronix SLC8000/SLC9000 before firmware v9.7.0.2, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882/SLCx-03/SLCx-02 contain a stack-based buffer overflow vulnerability that allows authenticated attackers to potentially execute arbitrary code by exploiting an undocumented mfc eeprom read command that copies unbounded user input into a bounded stack buffer before passing it to a system() call.
