An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-48769 in the wild and no public exploit code.\n\nAffected product: Apache NuttX RTOS. 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-2025-48769/ (Markdown: https://insights.sbomify.com/CVE-2025-48769/index.md)","id":"CVE-2025-48769","markdown":"https://insights.sbomify.com/CVE-2025-48769/index.md","name":"CVE-2025-48769","record":{"aliases":["GHSA-mrp2-wx3j-867f"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"NuttX RTOS","requires_auth":"none","summary":"A use-after-free in NuttX RTOS allows attackers with write access to corrupt memory and potentially execute code or modify data.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nuttx","vendor":"apache"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use After Free vulnerability was discovered in fs/vfs/fs_rename code of the Apache NuttX RTOS, that due recursive implementation and single buffer use by two different pointer variables allowed arbitrary user provided size buffer reallocation and write to the previously freed heap chunk, that in specific cases could cause unintended virtual filesystem rename/move operation results.\n\nThis issue affects Apache NuttX RTOS: from 7.20 before 12.11.0.\n\nUsers of virtual filesystem based services with write access especially when exposed over the network (i.e. FTP) are affected and recommended to upgrade to version 12.11.0 that fixes the issue.","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":"Apache NuttX RTOS: fs/vfs/fs_rename: use after free","id":"CVE-2025-48769","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Soar Cloud HRD Human Resource Management System - Deserialization of Untrusted Data","id":"CVE-2025-48780"},"packages":[],"prev":{"headline":"Apache NuttX RTOS: fs/inode: fs_inoderemove root inode removal","id":"CVE-2025-48768"},"products":["Apache NuttX RTOS"],"published":"2026-01-01","related":[{"cvss_score":9.8,"headline":"Apache NuttX RTOS: tools/bdf-converter.: tools/bdf-converter: Fix loop termination condition.","id":"CVE-2025-47868","kev_date_added":null,"published":"2025-06-16"},{"cvss_score":9.8,"headline":"Apache NuttX RTOS: examples/xmlrpc: Fix calls buffers size.","id":"CVE-2025-47869","kev_date_added":null,"published":"2025-06-16"},{"cvss_score":9.8,"headline":"Apache NuttX RTOS: NuttX Bluetooth Stack HCI and UART DoS/RCE Vulnerabilities.","id":"CVE-2025-35003","kev_date_added":null,"published":"2025-05-26"},{"cvss_score":9.8,"headline":"malloc, realloc and memalign implementations are vulnerable to integer wrap-arounds","id":"CVE-2021-26461","kev_date_added":null,"published":"2021-06-21"},{"cvss_score":9.8,"headline":"Apache NuttX (incubating) Out of Bound Write from invalid fragmentation offset value specified in the IP header","id":"CVE-2020-17529","kev_date_added":null,"published":"2020-12-09"},{"cvss_score":9.8,"headline":"Null dereference in Apache NuttX (incubating)","id":"CVE-2020-1939","kev_date_added":null,"published":"2020-05-12"},{"cvss_score":9.1,"headline":"Apache NuttX (incubating) Out of Bound Write from invalid TCP Urgent length","id":"CVE-2020-17528","kev_date_added":null,"published":"2020-12-09"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-05","vendors":["Apache Software Foundation"]},"summary":"A use-after-free in NuttX RTOS allows attackers with write access to corrupt memory and potentially execute code or modify data.","url":"https://insights.sbomify.com/CVE-2025-48769/"}
