{"id":"CVE-2025-38315","summary":"Bluetooth: btintel: Check dsbr size from EFI variable","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btintel: Check dsbr size from EFI variable\n\nSince the size of struct btintel_dsbr is already known, we can just\nstart there instead of querying the EFI variable size. If the final\nresult doesn't match what we expect also fail. This fixes a stack buffer\noverflow when the EFI variable is larger than struct btintel_dsbr.","modified":"2026-03-20T12:42:48.156180Z","published":"2025-07-10T07:42:22.569Z","related":["SUSE-SU-2025:02853-1","SUSE-SU-2025:02997-1","SUSE-SU-2025:03011-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","openSUSE-SU-2025:20081-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38315.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3aa1dc3c9060e335e82e9c182bf3d1db29220b1b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7b8526bb489780ccc0caffc446ecabec83cfe568"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9427f6081f37c795a8bd29d0ee72a4da3bd64af8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38315.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38315"},{"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":"eb9e749c0182affafadfbe5ded4503c4b5a9b57c"},{"fixed":"9427f6081f37c795a8bd29d0ee72a4da3bd64af8"},{"fixed":"7b8526bb489780ccc0caffc446ecabec83cfe568"},{"fixed":"3aa1dc3c9060e335e82e9c182bf3d1db29220b1b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-38315.json"}}],"schema_version":"1.7.5"}
