It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-10664 exists.\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-2026-10664/ (Markdown: https://insights.sbomify.com/CVE-2026-10664/index.md)","id":"CVE-2026-10664","markdown":"https://insights.sbomify.com/CVE-2026-10664/index.md","name":"CVE-2026-10664","record":{"aliases":["GHSA-3r6j-pm38-r43m"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Zephyr RTOS","requires_auth":"none","summary":"Out-of-bounds write in nRF70 Wi-Fi driver allows memory corruption if coprocessor firmware sends malformed power-save events, requiring CONFIG_NRF70_STA_MODE.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zephyr","cpe":[{"product":"zephyr","vendor":"zephyrproject"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The nRF70 Wi-Fi driver's power-save event handler nrf_wifi_event_proc_get_power_save_info() in drivers/wifi/nrf_wifi/src/wifi_mgmt.c copied TWT (Target Wake Time) flow entries from an nrf_wifi_umac_event_power_save_info event into the fixed-size twt_flows[WIFI_MAX_TWT_FLOWS] (8-element) array of a caller-supplied struct wifi_ps_config, looping over event-provided num_twt_flows without validating it against WIFI_MAX_TWT_FLOWS or checking event_len. When num_twt_flows exceeds 8, the handler writes past the destination array (which is typically on the caller's stack, e.g. the wifi ps shell command) -- an out-of-bounds write of ~40-byte TWT entries -- and reads twt_flow_info[i] past the event buffer. The event is delivered by the nRF70 co-processor firmware in response to a host-initiated power-save GET, so reaching the overflow requires the firmware to emit a malformed or out-of-range event; the trust boundary is host-to-trusted-coprocessor rather than a direct remote-AP write, with over-the-air influence on the flow count being indirect and bounded by the 3-bit TWT flow-id space. Affected: builds with CONFIG_NRF70_STA_MODE on releases through v4.4.0. The fix rejects events with num_twt_flows \u003e WIFI_MAX_TWT_FLOWS or with event_len shorter than the claimed entries, and adds a NULL check on the caller buffer.","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":"Out-of-bounds write in nRF70 Wi-Fi driver power-save event handler (unbounded TWT flow count)","id":"CVE-2026-10664","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zephyrproject:zephyr","products":["zephyrproject:zephyr"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Heap buffer overflow on WireGuard receive path via unbounded incoming packet length","id":"CVE-2026-10665"},"packages":[],"prev":{"headline":"Use-after-free / double-free of the root USB device in the experimental USB host stack","id":"CVE-2026-10663"},"products":["zephyr"],"published":"2026-07-12","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["zephyrproject"]},"summary":"Out-of-bounds write in nRF70 Wi-Fi driver allows memory corruption if coprocessor firmware sends malformed power-save events, requiring CONFIG_NRF70_STA_MODE.","url":"https://insights.sbomify.com/CVE-2026-10664/"}
