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-2026-25508 in the wild and no public exploit code.\n\nAffected product: espressif esp-idf. 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-2026-25508/ (Markdown: https://insights.sbomify.com/CVE-2026-25508/index.md)","id":"CVE-2026-25508","markdown":"https://insights.sbomify.com/CVE-2026-25508/index.md","name":"CVE-2026-25508","record":{"aliases":["GHSA-9j5x-rf36-54x9"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Espressif IoT framework","requires_auth":"none","summary":"Remote attackers can trigger memory corruption in Espressif IoT devices during BLE provisioning via out-of-bounds reads, potentially leading to code execution or crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"esp-idf","vendor":"espressif"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.2, 5.4.3, 5.3.4, 5.2.6, and 5.1.6, an out-of-bounds read vulnerability was reported in the BLE ATT Prepare Write handling of the BLE provisioning transport (protocomm_ble). The issue can be triggered by a remote BLE client while the device is in provisioning mode. The transport accumulated prepared-write fragments in a fixed-size buffer but incorrectly tracked the cumulative length. By sending repeated prepare write requests with overlapping offsets, a remote client could cause the reported length to exceed the allocated buffer size. This inflated length was then passed to provisioning handlers during execute-write processing, resulting in an out-of-bounds read and potential memory corruption. This issue has been patched in versions 5.5.3, 5.4.4, 5.3.5, 5.2.7, and 5.1.7.","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":"ESF-IDF Has Memory Safety Vulnerabilities in BLE Provisioning","id":"CVE-2026-25508","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"CI4MS Vulnerable to User Email Enumeration via Password Reset Flow","id":"CVE-2026-25509"},"packages":[],"prev":{"headline":"ESF-IDF Has Use-after-free Vulnerability in BLE Provisioning","id":"CVE-2026-25507"},"products":["esp-idf"],"published":"2026-02-04","related":[{"cvss_score":9.3,"headline":"ESF-IDF: Out-of-Bounds Write in ESP-TEE Secure Service Wrappers","id":"CVE-2026-45328","kev_date_added":null,"published":"2026-06-10"},{"cvss_score":8.8,"headline":"Auth bypass in n/a","id":"CVE-2024-53406","kev_date_added":null,"published":"2025-03-13"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2021-28139","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":8.1,"headline":"Information disclosure in n/a","id":"CVE-2024-33453","kev_date_added":null,"published":"2024-10-17"},{"cvss_score":8.1,"headline":"Weak cryptography in n/a","id":"CVE-2019-12587","kev_date_added":null,"published":"2019-09-04"},{"cvss_score":7.5,"headline":"ESF-IDF: Remote Null Pointer Dereference in WebSocket Server","id":"CVE-2026-45541","kev_date_added":null,"published":"2026-06-10"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-51428","kev_date_added":null,"published":"2024-11-07"}],"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":"2026-02-04","vendors":["espressif"]},"summary":"Remote attackers can trigger memory corruption in Espressif IoT devices during BLE provisioning via out-of-bounds reads, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/CVE-2026-25508/"}
