The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Bluetooth: MGMT: validate Add Extended Advertising Data length MGMT_OP_ADD_EXT_ADV_DATA is registered as a     variable-length command, with MGMT_ADD_EXT_ADV_DATA_SIZE as the fixed header size. The handler then uses     cp->adv_data_len and cp->scan_rsp_len to validate and copy cp->data, but it never checks that those bytes     are part of the mgmt command payload. A short command can therefore make add_ext_adv_data() pass an out-     of-bounds pointer into tlv_data_is_valid(). If the bytes beyond the command buffer are addressable, they     can also be copied into the advertising instance as scan response data, where the caller can read them     back via MGMT_OP_GET_ADV_INSTANCE. The trigger requires CAP_NET_ADMIN in the initial user namespace; KASAN     reports an 8-byte slab-out-of-bounds read. Reject commands whose length does not match the fixed header     plus both advertising data lengths before parsing cp->data. (CVE-2026-64126)

Note that Nessus relies on the presence of the package as reported by the vendor.
