CVE-2026-64403

CVE-2026-64403 covers a Linux kernel Bluetooth L2CAP bug. l2cap_get_conf_opt() derives the option length from opt->len and dereferences opt->val before ensuring the buffer contains opt->len bytes, allowing an out-of-bounds read (up to 4 bytes) before a check. Callers detect malformed opt...
