It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-55095 in the wild and no public exploit code.\n\nAffected product: Eclipse ThreadX - USBX. 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-2025-55095/ (Markdown: https://insights.sbomify.com/CVE-2025-55095/index.md)","id":"CVE-2025-55095","markdown":"https://insights.sbomify.com/CVE-2025-55095/index.md","name":"CVE-2025-55095","record":{"aliases":["GHSA-qfmp-wch9-rpv2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ThreadX USBX","requires_auth":"low_privilege","summary":"A malicious USB mass storage device can cause a stack overflow and denial of service in Eclipse ThreadX USBX due to unbounded recursion in partition mounting.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"threadx_usbx","vendor":"eclipse"}],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-674","name":"Uncontrolled Recursion"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"The function _ux_host_class_storage_media_mount() is responsible for mounting partitions on a USB mass storage device. When it encounters an extended partition entry in the partition table, it recursively calls itself to mount the next logical partition.\n\nThis recursion occurs in _ux_host_class_storage_partition_read(), which parses up to four partition entries.
