An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-55091 exists.\n\nAffected product: Eclipse Foundation NetX Duo. 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-2025-55091/ (Markdown: https://insights.sbomify.com/CVE-2025-55091/index.md)","id":"CVE-2025-55091","markdown":"https://insights.sbomify.com/CVE-2025-55091/index.md","name":"CVE-2025-55091","record":{"aliases":["GHSA-pf5q-r6q5-6j2f"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"NetX Duo networking stack","requires_auth":"none","summary":"An out-of-bounds read in NetX Duo allows attackers to cause denial of service or disclose memory contents via crafted Ethernet packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"threadx_netx_duo","vendor":"eclipse"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_ip_packet_receive() function when received an Ethernet with type set as IP but no IP data.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Potential out of bound read in _nx_ip_packet_receive()","id":"CVE-2025-55091","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Potential out of bound read in _nx_ipv4_option_process()","id":"CVE-2025-55092"},"packages":[],"prev":{"headline":"Potential out of bound read issue in _nx_ipv4_packet_receive() in NetX Duo","id":"CVE-2025-55090"},"products":["NetX Duo"],"published":"2025-10-16","related":[{"cvss_score":8.8,"headline":"Web http client: Unchecked Server-Side Malicious Packet Issue","id":"CVE-2025-55085","kev_date_added":null,"published":"2025-10-17"},{"cvss_score":8.7,"headline":"Denial of service in Eclipse ThreadX - NetX Duo","id":"CVE-2025-55102","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":7.5,"headline":"Memory corruption in Eclipse ThreadX - NetX Duo","id":"CVE-2026-11576","kev_date_added":null,"published":"2026-06-19"},{"cvss_score":7.1,"headline":"Eclipse ThreadX NetX Duo HTTP component server denial of service","id":"CVE-2025-2260","kev_date_added":null,"published":"2025-04-06"},{"cvss_score":7.1,"headline":"Eclipse ThreadX NetX Duo HTTP server denial of service","id":"CVE-2025-0726","kev_date_added":null,"published":"2025-02-21"},{"cvss_score":7,"headline":"Integer wraparound, under-allocation, and heap buffer overflow in Eclipse ThreadX NetX Duo __portable_aligned_alloc()","id":"CVE-2024-2452","kev_date_added":null,"published":"2024-03-26"},{"cvss_score":6.9,"headline":"Potential out of bound read in _nx_ipv4_option_process()","id":"CVE-2025-55092","kev_date_added":null,"published":"2025-10-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-16","vendors":["Eclipse Foundation"]},"summary":"An out-of-bounds read in NetX Duo allows attackers to cause denial of service or disclose memory contents via crafted Ethernet packets.","url":"https://insights.sbomify.com/CVE-2025-55091/"}
