{"id":"CVE-2026-98111","summary":"Bluetooth: btintel: validate version TLV value lengths","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btintel: validate version TLV value lengths\n\nbtintel_parse_version_tlv() verifies that a complete TLV is present in\nthe response, but it does not ensure that the value is long enough for\nthe specific TLV type. A short value can therefore cause an\nout-of-bounds read through get_unaligned_le16(), get_unaligned_le32(),\nor memcpy().\n\nReject values shorter than the minimum required by each known TLV type.\nAlso reject responses that do not contain the Command Complete Status\nfield.","modified":"2026-09-27T03:47:39.554715023Z","published":"2026-09-25T10:35:58.728Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98111.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5ec43df2830b73e004147303bf7914ca884d6770"},{"type":"WEB","url":"https://git.kernel.org/stable/c/76948d207d0978a613ce06a05cba07284a5578a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/83499ac3ca62e43ed40f7574b13ed398a6891511"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a086c0892969bf8a0151b0f12bd14a68827c88b2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98111.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98111"},{"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":"57375beef71af9f245e88357fa71d9600650cb7d"},{"fixed":"83499ac3ca62e43ed40f7574b13ed398a6891511"},{"fixed":"76948d207d0978a613ce06a05cba07284a5578a7"},{"fixed":"5ec43df2830b73e004147303bf7914ca884d6770"},{"fixed":"a086c0892969bf8a0151b0f12bd14a68827c88b2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98111.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98111.json"}}],"schema_version":"1.9.0"}
