  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nnet: caif: clear client service pointer on teardown\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.\nWhen the socket is later destroyed, `caif_sock_destructor()` calls\n`caif_free_client()` again and dereferences the freed service pointer.\nClear the client/service links before releasing the service object so\nrepeated teardown becomes harmless.", "A flaw was found in the Linux kernel's CAIF network module. When a client is torn down, the `caif_free_client()` function frees a service pointer but leaves it in a stale state. If the socket is later destroyed, `caif_free_client()` may be called again, attempting to use the previously freed pointer. This can lead to memory corruption and potentially cause a system crash, resulting in a Denial of Service (DoS)." ],
