It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-10651 in the wild and no public exploit code.\n\nAffected product: Zephyrproject Zephyr. 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-2026-10651/ (Markdown: https://insights.sbomify.com/CVE-2026-10651/index.md)","id":"CVE-2026-10651","markdown":"https://insights.sbomify.com/CVE-2026-10651/index.md","name":"CVE-2026-10651","record":{"aliases":["GHSA-p93g-3r68-cj53","UBUNTU-CVE-2026-10651"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zephyr RTOS","requires_auth":"none","summary":"A remote Bluetooth peer can cause a denial of service in Zephyr RTOS by sending a malformed SDP record that triggers an out-of-bounds read.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zephyr","cpe":[{"product":"zephyr","vendor":"zephyrproject"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"bt_sdp_parse_attribute() in subsys/bluetooth/host/classic/sdp.c validated only that the SDP record buffer held the type-marker byte plus the 2-byte attribute ID (a check of buf-\u003elen \u003c 3) but then read a fourth byte, the data-element descriptor (type), via net_buf_simple_pull_u8(). Because net_buf_simple_pull_u8() dereferences buf-\u003edata[0] before its only bounds guard (an __ASSERT_NO_MSG that compiles out when CONFIG_ASSERT is disabled, the production default), a record of exactly three bytes (0x09 followed by a 2-byte attribute ID) causes a one-byte read past the end of the logical buffer. The parser is reachable from inbound, remote-controlled data: a Bluetooth BR/EDR peer acting as an SDP server returns discovery-response records that are stored verbatim in the client receive buffer and parsed via the public bt_sdp_get_attr()/bt_sdp_has_attr()/bt_sdp_record_parse() helpers. The over-read is bounded to a single byte that is used only as an internal length selector and is never leaked to the attacker; subsequent length checks then reject the malformed record. Realistic impact is therefore limited to an edge-case denial of service (a fault only if the record ends exactly at a mapped-memory boundary, or a deterministic assert panic when CONFIG_ASSERT=y). Affects Zephyr v4.3.0 and v4.4.0; fixed by adding sizeof(type) to the length check.","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":"Out-of-bounds read in Bluetooth Classic SDP attribute parsing (`bt_sdp_parse_attribute`)","id":"CVE-2026-10651","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zephyrproject:zephyr","products":["zephyrproject:zephyr"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Out-of-bounds read in Zephyr DNS resolver TXT/SRV record parsing (unvalidated `rdlength`)","id":"CVE-2026-10652"},"packages":[],"prev":{"headline":"warmcat libwebsockets SSH Protocol sshd.c lws_ssh_parse_plaintext resource consumption","id":"CVE-2026-10650"},"products":["zephyr"],"published":"2026-06-22","related":[{"cvss_score":9.8,"headline":"Out-of-bounds read/write in HTTP WebSocket upgrade via non-null-terminated Sec-WebSocket-Key","id":"CVE-2026-5067","kev_date_added":null,"published":"2026-06-09"},{"cvss_score":9.8,"headline":"Bluetooth HCI Error Handling Double Free","id":"CVE-2022-3806","kev_date_added":null,"published":"2023-01-19"},{"cvss_score":9.8,"headline":"Memory corruption in getaddrinfo","id":"CVE-2017-14199","kev_date_added":null,"published":"2019-04-12"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2018-1000800","kev_date_added":null,"published":"2018-09-06"},{"cvss_score":9.6,"headline":"DOS: Incorrect handling of the initial HCI ACL_MTU handshake packet leads to crash of bluetooth host layer","id":"CVE-2021-3329","kev_date_added":null,"published":"2023-02-26"},{"cvss_score":9.6,"headline":"DoS: Invalid Initialization in le_read_buffer_size_complete","id":"CVE-2023-0397","kev_date_added":null,"published":"2023-01-19"},{"cvss_score":9.6,"headline":"Usb bluetooth device ACL read cb buffer overflow","id":"CVE-2021-3966","kev_date_added":null,"published":"2023-01-11"}],"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":"2026-10-15","vendors":["zephyrproject"]},"summary":"A remote Bluetooth peer can cause a denial of service in Zephyr RTOS by sending a malformed SDP record that triggers an out-of-bounds read.","url":"https://insights.sbomify.com/CVE-2026-10651/"}
