Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-9246 exists.\n\nAffected product: Linksys Re6250 Firmware. 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-2025-9246/ (Markdown: https://insights.sbomify.com/CVE-2025-9246/index.md)","id":"CVE-2025-9246","markdown":"https://insights.sbomify.com/CVE-2025-9246/index.md","name":"CVE-2025-9246","record":{"aliases":["GHSA-m2h7-w2mc-vj88"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linksys Wi-Fi Range Extender","requires_auth":"low_privilege","summary":"Remote attackers can trigger a stack-based buffer overflow in Linksys range extenders via the check_port_conflict function, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"re6250_firmware","vendor":"linksys"},{"product":"re6300_firmware","vendor":"linksys"},{"product":"re6350_firmware","vendor":"linksys"},{"product":"re6500_firmware","vendor":"linksys"},{"product":"re7000_firmware","vendor":"linksys"},{"product":"re9000_firmware","vendor":"linksys"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A flaw has been found in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001.
