Answer in brief
CVE-2024-42132 records a Unknown severity vulnerability in bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX Syzbot hit warning in hci_conn_del() caused by freeing handle that was not allocated using ida allocator. This is caused by handle bigger than HCI_CONN_HANDLE_MAX passed by hci_le_big_sync_established_evt(), which makes code think it's unset connection. Add same check for handle upper bound as in hci_conn_set_handle() to prevent warning.
