      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nkeys: Fix overwrite of key expiration on instantiation\n\nThe expiry time of a key is unconditionally overwritten during\ninstantiation, defaulting to turn it permanent. This causes a problem\nfor DNS resolution as the expiration set by user-space is overwritten to\nTIME64_MAX, disabling further DNS updates. Fix this by restoring the\ncondition that key_set_expiry is only called when the pre-parser sets a\nspecific expiry."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: claves: se corrige la sobrescritura de la caducidad de la clave al crear instancias. El tiempo de caducidad de una clave se sobrescribe incondicionalmente durante la creaci\u00f3n de instancias, y de forma predeterminada se vuelve permanente. Esto causa un problema para la resoluci\u00f3n de DNS ya que la caducidad establecida por el espacio de usuario se sobrescribe en TIME64_MAX, lo que deshabilita m\u00e1s actualizaciones de DNS. Solucione este problema restaurando la condici\u00f3n de que key_set_expiry solo se llama cuando el analizador previo establece una caducidad espec\u00edfica."
