  "summary": "net: caif: clear client service pointer on teardown",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: caif: clear client service pointer on teardown\n\n`caif_connect()` can tear down an existing client after remote shutdown by\ncalling `caif_disconnect_client()` followed by `caif_free_client()`.\n`caif_free_client()` releases the service layer referenced by\n`adap_layer->dn`, but leaves that pointer stale.\n\nWhen the socket is later destroyed, `caif_sock_destructor()` calls\n`caif_free_client()` again and dereferences the freed service pointer.\n\nClear the client/service links before releasing the service object so\nrepeated teardown becomes harmless.",
