In the Linux kernel, the following vulnerability has been resolved: keys: Fix overwrite of key expiration on instantiation The expiry time of a key is unconditionally overwritten during instantiation, defaulting to turn it permanent. This causes a problem for DNS resolution as the expiration set by user-space is overwritten to TIME64_MAX, disabling further DNS updates. Fix this by restoring the condition that key_set_expiry is only called when the pre-parser sets a specific expiry.

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 creación de instancias, y de forma predeterminada se vuelve permanente. Esto causa un problema para la resolución de DNS ya que la caducidad establecida por el espacio de usuario se sobrescribe en TIME64_MAX, lo que deshabilita más actualizaciones de DNS. Solucione este problema restaurando la condición de que key_set_expiry solo se llama cuando el analizador previo establece una caducidad específica.
