Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-11618 in the wild and no public exploit code.\n\nAffected product: AWS FreeRTOS-Plus-TCP. 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-2025-11618/ (Markdown: https://insights.sbomify.com/CVE-2025-11618/index.md)","id":"CVE-2025-11618","markdown":"https://insights.sbomify.com/CVE-2025-11618/index.md","name":"CVE-2025-11618","record":{"aliases":["GHSA-6fh9-mqxj-hmwj"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"FreeRTOS TCP stack","requires_auth":"low_privilege","summary":"Attackers can cause a denial of service in IPv6-enabled FreeRTOS devices by sending malformed UDP packets that trigger an invalid pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[{"product":"freertos-plus-tcp","vendor":"amazon"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A missing validation check in FreeRTOS-Plus-TCP's UDP/IPv6 packet processing code can lead to an invalid pointer dereference when receiving a UDP/IPv6 packet with an incorrect IP version field in the packet header. This issue only affects applications using IPv6.\n\nWe recommend upgrading to the latest version and ensure any forked or derivative code is patched to incorporate the new fixes.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Invalid Pointer Dereference when receiving UDP/IPv6 packets in FreeRTOS-Plus-TCP","id":"CVE-2025-11618","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Security feature bypass in Devolutions Server","id":"CVE-2025-11619"},"packages":[],"prev":{"headline":"Buffer Over-read when receiving IPv6 packets with incorrect payload length in FreeRTOS-Plus-TCP","id":"CVE-2025-11617"},"products":["FreeRTOS-Plus-TCP"],"published":"2025-10-10","related":[{"cvss_score":9.6,"headline":"FreeRTOS-Plus-TCP Buffer Over-Read in DNS Response Parser","id":"CVE-2024-38373","kev_date_added":null,"published":"2024-06-24"},{"cvss_score":7.2,"headline":"Integer Underflow in DHCPv6 Sub-Option Parser in FreeRTOS-Plus-TCP","id":"CVE-2026-7424","kev_date_added":null,"published":"2026-04-29"},{"cvss_score":7.1,"headline":"MAC Address Validation Bypass in FreeRTOS-Plus-TCP IPv4 and IPv6 Packet Processing","id":"CVE-2026-7422","kev_date_added":null,"published":"2026-04-29"},{"cvss_score":6.1,"headline":"Out-of-Bounds Write via Unsanitized Prefix Length in Router Advertisement Processing in FreeRTOS-Plus-TCP","id":"CVE-2026-7426","kev_date_added":null,"published":"2026-04-29"},{"cvss_score":6,"headline":"Integer Underflow in ICMP Echo Reply Processing in FreeRTOS-Plus-TCP","id":"CVE-2026-7423","kev_date_added":null,"published":"2026-04-29"},{"cvss_score":6,"headline":"Out-of-Bounds Read in Router Advertisement Option Parser in FreeRTOS-Plus-TCP","id":"CVE-2026-7425","kev_date_added":null,"published":"2026-04-29"},{"cvss_score":5.3,"headline":"Buffer Over-read when receiving improperly sized ICMPv6 packets in FreeRTOS-Plus-TCP","id":"CVE-2025-11616","kev_date_added":null,"published":"2025-10-10"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-10","vendors":["AWS"]},"summary":"Attackers can cause a denial of service in IPv6-enabled FreeRTOS devices by sending malformed UDP packets that trigger an invalid pointer dereference.","url":"https://insights.sbomify.com/CVE-2025-11618/"}
