      <title>CVE-2024-42132 — bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-42132</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX&lt;/p&gt;
&lt;p&gt;Syzbot hit warning in hci_conn_del() caused by freeing handle that was
not allocated using ida allocator.&lt;/p&gt;
&lt;p&gt;This is caused by handle bigger than HCI_CONN_HANDLE_MAX passed by
hci_le_big_sync_established_evt(), which makes code think it&amp;#39;s unset
connection.&lt;/p&gt;
&lt;p&gt;Add same check for handle upper bound as in hci_conn_set_handle() to
prevent warning.&lt;/p&gt;</description>
