A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

net: caif: clear client service pointer on teardown

caif_connect() can tear down an existing client after remote shutdown by calling caif_disconnect_client() followed by caif_free_client(). caif_free_client() releases the service layer referenced by adap_layer->dn, but leaves that pointer stale.

When the socket is later destroyed, caif_sock_destructor() calls caif_free_client() again and dereferences the freed service pointer.

Clear the client/service links before releasing the service object so repeated teardown becomes harmless.
