Summary
In the Linux kernel, the following vulnerability has been resolved: vsock: remove vsock from connected table when connect is interrupted by a signal vsock_connect() expects that the socket could already be in the TCP_ESTABLISHED state when the connecting task wakes up with a signal pending. If this happens the socket will be in the connected table, and it is not removed when the socket state is reset. In this situation it's common for the process to retry connect(), and if the connection is successful the socket will be added to the connected table a second time, corrupting the list. Prevent this by calling vsock_remove_connected() if a signal is received while waiting for a connection. This is harmless if the socket is not in the connected table, and if it is in the table then removing it will prevent list corruption from a double add. Note for backporting: this patch requires d5afa82c977e ("vsock: correct removal of socket from the list"), which is in all current stable trees except 4.9.y.

If this happens the socket will be in the connected table, and\\nit is not removed when the socket state is reset. In this situation it\u0027s\\ncommon for the process to retry connect(), and if the connection is\\nsuccessful the socket will be added to the connected table a second\\ntime, corrupting the list.\\n\\nPrevent this by calling vsock_remove_connected() if a signal is received\\nwhile waiting for a connection. This is harmless if the socket is not in\\nthe connected table, and if it is in the table then removing it will\\nprevent list corruption from a double add.\\n\\nNote for backporting: this patch requires d5afa82c977e (\\\"vsock: correct\\nremoval of socket from the list\\\"), which is in all current stable trees\\nexcept 4.9.y.\"},{\"lang\":\"es\",\"value\":\"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vsock: elimina vsock de la tabla conectada cuando la conexi\u00f3n es interrumpida por una se\u00f1al vsock_connect() espera que el socket ya est\u00e9 en el estado TCP_ESTABLISHED cuando la tarea de conexi\u00f3n se activa con una se\u00f1al pendiente.
