{"id":"CVE-2026-98291","summary":"Bluetooth: btintel_pcie: fix off-by-one bounds check in RX submit","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btintel_pcie: fix off-by-one bounds check in RX submit\n\nbtintel_pcie_submit_rx() used frbd_index \u003e rxq-\u003ecount to guard the\nFRBD array access, allowing frbd_index == rxq-\u003ecount to pass through\nand index one element past the end of the array. Change the check to\n\u003e= rxq-\u003ecount so every out-of-range index is rejected.\n\nThis issue was reported by Claude Mythos.","modified":"2026-10-08T02:52:56.058151210Z","published":"2026-10-06T08:45:51.021Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98291.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/18464860ce27af0dccd2fc72830610b85b518cff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ea5a87a5a7ae58cb2662b8a7d06f209383e1765"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b5214d72bfdf8ef7744d0c8147e6ebb09b36b259"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de4c3c72bcc6e8474f70c22427f94ca44bccd890"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98291.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98291"},{"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":"c2b636b3f788d10486a6691ad6dd3ec4c93bd78e"},{"fixed":"b5214d72bfdf8ef7744d0c8147e6ebb09b36b259"},{"fixed":"18464860ce27af0dccd2fc72830610b85b518cff"},{"fixed":"de4c3c72bcc6e8474f70c22427f94ca44bccd890"},{"fixed":"2ea5a87a5a7ae58cb2662b8a7d06f209383e1765"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98291.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.10.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98291.json"}}],"schema_version":"1.9.0"}
