📋 Description
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: ensure no dangling hcon references in iso_conn
After iso_conn_del(), ISO sockets should not dereference the hcon any more. Currently, clearing iso_conn::hcon relies on iso_conn_del() releasing the last reference to the iso_conn.
Simplify this by explicitly clearing conn->hcon in iso_conn_del(), to avoid more complex reasoning on races about who holds the last reference.
