  "details": "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-\u003ehcon in iso_conn_del(), to avoid more complex reasoning on races about who holds the last reference.",
