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-2026-64407 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-64407/ (Markdown: https://insights.sbomify.com/CVE-2026-64407/index.md)","id":"CVE-2026-64407","markdown":"https://insights.sbomify.com/CVE-2026-64407/index.md","name":"CVE-2026-64407","record":{"aliases":["BELL-CVE-2026-64407","DEBIAN-CVE-2026-64407","GHSA-vpwp-65cp-hgqm","ROOT-OS-UBUNTU-2204-CVE-2026-64407","UBUNTU-CVE-2026-64407"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth driver","requires_auth":"low_privilege","summary":"A malicious Bluetooth controller can trigger an out-of-bounds read in the Linux kernel btnxpuart driver, leaking kernel memory contents over UART.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btnxpuart: Fix out-of-bounds firmware read in nxp_recv_fw_req_v3()\n\nDuring the v3 firmware download the controller sends a v3_data_req with a\n32 bit offset and a 16 bit len. nxp_recv_fw_req_v3() checks only the lower\nbound of the offset and then sends firmware from that offset.\n\n  nxpdev-\u003efw_dnld_v3_offset = offset - nxpdev-\u003efw_v3_offset_correction;\n  serdev_device_write_buf(nxpdev-\u003eserdev, nxpdev-\u003efw-\u003edata +\n                          nxpdev-\u003efw_dnld_v3_offset, len);\n\nNothing checks that fw_dnld_v3_offset + len stays within nxpdev-\u003efw-\u003esize,\nso a controller that asks for an offset or length past the firmware image\nmakes the driver read past the end of nxpdev-\u003efw-\u003edata and send that\nmemory back over UART.\n\nnxp_recv_fw_req_v1() already bounds the same write.
