{"id":"CVE-2026-80759","summary":"Bluetooth: hci_aml: validate firmware segment lengths","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_aml: validate firmware segment lengths\n\naml_download_firmware() reads two lengths from the firmware header and\nuses them to build pointers before checking that the header and segment\ndata are present. A truncated or inconsistent firmware image can make\nthe driver read past firmware-\u003edata while constructing TCI commands.\n\nReject images shorter than the header and ensure that the ICCM and DCCM\nranges fit within the loaded firmware before downloading either segment.","modified":"2026-09-06T03:46:57.889437871Z","published":"2026-09-04T15:12:28.900Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80759.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2763b8bcb504e30ec955474f51b99ce42fc62f3b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2bf6b9baca9372ea51b6d0f2820dc9bf29a83ef4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6c70253462902d835e843b470f74aa816d60af80"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7733b01ed13685773ccda91035a46f87d4cfef7c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e1534d49a7b8ba728e84b020f6d802aa1cb759d9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80759.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80759"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"37bac77e4649e8158698a60addc22ec4faf5649a"},{"fixed":"7733b01ed13685773ccda91035a46f87d4cfef7c"},{"fixed":"e1534d49a7b8ba728e84b020f6d802aa1cb759d9"},{"fixed":"6c70253462902d835e843b470f74aa816d60af80"},{"fixed":"2763b8bcb504e30ec955474f51b99ce42fc62f3b"},{"fixed":"2bf6b9baca9372ea51b6d0f2820dc9bf29a83ef4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80759.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.106"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.47"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.11"}]},{"type":"ECOSYSTEM","events":[{"introduced":"7.2.0"},{"fixed":"7.2.1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80759.json"}}],"schema_version":"1.9.0"}
